# S3

> Amazon cloud object storage service connector

![Amazon S3 Logo](https://mintcdn.com/pipeshub/8k-iBPRh1yJZHQe1/logo/s3.png?fit=max\&auto=format\&n=8k-iBPRh1yJZHQe1\&q=85\&s=e6dc50da44f49b80d7afa38eba29bfb4)

Amazon S3

Cloud object storage service

✅ Ready

📖 Documentation Available

## Overview

Amazon S3 (Simple Storage Service) is a scalable object storage service designed to store and retrieve any amount of data from anywhere on the web. It provides industry-leading scalability, data availability, security, and performance.

The S3 connector enables you to sync files and folders from your S3 buckets into PipesHub, making your cloud storage content searchable through AI-powered search and accessible across your organization.

### S3 Data Structure

The connector understands S3's hierarchical structure:

**Buckets → Folders → Files**

| Entity | Description |
| - | - |
| **Buckets** | Top-level containers for organizing objects (similar to root directories) |
| **Folders** | Logical groupings of objects using prefixes (e.g., `documents/reports/`) |
| **Files** | Individual objects stored in buckets with unique keys (paths) |

### What Gets Synced

The connector indexes the following content for AI-powered search:

* **Files**: Supported file types stored in S3 buckets, including documents and images
* **Folders**: Directory structure and organization
* **Metadata**: File names, sizes, modification dates, MIME types
* **Permissions**: Access control based on bucket and object permissions

***

## Configuration Guide

> **Setup**
>
> ### Setup Overview
>
> The S3 connector provides access to your AWS S3 buckets through Access Key authentication. It syncs files, folders, and metadata, enabling comprehensive search and access across your S3 content.
>
> ### Authentication
>
> The S3 connector uses **AWS Access Key ID and Secret Access Key** for authentication. This method allows secure programmatic access to your S3 buckets without requiring OAuth setup.
>
> > [!NOTE]
> >
> > Access Key authentication is simpler to set up than OAuth but requires you to manage AWS IAM credentials. Ensure you follow AWS security best practices when creating and storing access keys.
>
> ## How to configure and enable the S3 Connector

>
> ### Step 4: Open S3 in PipesHub
>
> 1. Open the PipesHub app.
> 2. In the left sidebar, click **Connectors** (under **Workspace**).
> 3. Find the **S3** tile.
> 4. Click **+ Setup** on the tile.
>
> A panel called **S3 Configuration** opens on the right. It has two tabs: **Authenticate Instance** and **Configure Records**. You start on **Authenticate Instance**.
>
> ### Step 5: Fill in your S3 credentials
>
> ![S3 Authenticate Instance tab in PipesHub](https://mintcdn.com/pipeshub/WKpUe-DlJrX4Xz-X/images/connectors/s3/authenticate_tab.png?fit=max\&auto=format\&n=WKpUe-DlJrX4Xz-X\&q=85\&s=72d506352140dd83d74474f6dfda2afc)
>
> Fill in the fields from top to bottom:
>
> 1. **Instance name** — type any name you like (for example `S3`). This is just a label so you can recognise it later.
>
> 2. **Access Key** — paste the **Access Key ID** you copied from AWS in Step 3.
>
> 3. **Secret Key** — paste the **Secret Access Key** you copied from AWS in Step 3.
>
> 4. Click **Next →** (bottom right).
>
> > [!WARNING]
> >
> > Paste the keys exactly as you copied them. Extra spaces or line breaks will make the connection fail.
>
> > [!NOTE]
> >
> > The two links at the top (**S3 Access Key Setup** and **Pipeshub Documentation**) are just help links. You can ignore them if you've already followed Steps 1–3.
>
> ### Step 6: Choose how often S3 should sync
>
> You're now on the **Configure Records** tab. The top part is called **Sync settings**.
>
> ![S3 Configure Records tab in PipesHub — sync settings and filters](https://mintcdn.com/pipeshub/WKpUe-DlJrX4Xz-X/images/connectors/s3/configure_tab.png?fit=max\&auto=format\&n=WKpUe-DlJrX4Xz-X\&q=85\&s=6cdd0b462fd8ea80c3598f43831a35d7)
>
> 1. **Sync Strategy** — pick one:
>    * **Scheduled** — PipesHub checks S3 for new or changed files automatically. (Recommended.)
>    * **Manual** — nothing is pulled until you click **Sync** yourself.
> 2. **Sync Interval** — only shown if you chose **Scheduled**. Pick how often to check S3 (for example `1 Hour`).
>
> ### Step 7: Pick what to sync (filters)
>
> Still on the same tab, scroll down to **Indexing & sync filters**. Filters let you limit what PipesHub pulls from S3. **If you don't add any filters, everything will be synced.**
>
> 1. **Enable Manual Indexing** — leave this **off**. (Turning it on stops PipesHub from automatically indexing new files for search.)
>
> 2. Click **+ Add filter** to add a filter. You'll see these options:
>    * **Bucket Names** — pick which S3 buckets to include or exclude. PipesHub loads your bucket list automatically — just select from the dropdown.
>    * **Folders** — include or exclude folders inside a bucket, as paths from the bucket root, e.g. `reports` (which covers `reports/2026/q1.pdf` too).
>    * **File Extensions** — include or exclude specific file types. Type them comma-separated, e.g. `pdf, docx, txt`.
>    * **Modified Date** — only sync files changed after / before / between the dates you choose.
>    * **Created Date** — same idea, but based on when the file was first uploaded to S3.
>
> 3. Click **Save Configuration** (bottom right) when you're done.
>
> > [!NOTE]
> >
> > You can change filters any time later. New filters take effect on the next sync. When you narrow them, PipesHub removes the files they now leave out, search results included:
> >
> > * **Folders:** files the new **Folders** filter leaves out are removed on the next sync: outside the named folders with **In**, inside them with **Not In**.
> > * **File Extensions** and dates: files left out are removed once a sync has listed everything in scope from start to finish (the whole bucket, or each included folder when **Folders** is set to **In**).
> > * **Bucket Names:** with *In*, only the buckets you pick sync; with *Not In*, every bucket except those. A bucket the filter newly leaves out stops syncing, and the files already synced from it are removed on the next sync.
>
> ### Step 8: Turn on sync
>
> After saving, the S3 tile now shows a card for your new instance.
>
> ![S3 instance card with Sync Paused and Sync Enabled toggle](https://mintcdn.com/pipeshub/WKpUe-DlJrX4Xz-X/images/connectors/s3/instance_card.png?fit=max\&auto=format\&n=WKpUe-DlJrX4Xz-X\&q=85\&s=98db9842ee6447a8865450983441b92b)
>
> Right now the card says **Sync Paused** — nothing is being synced yet.
>
> 1. Find the **Sync Enabled** row at the bottom of the card.
> 2. Click the toggle so it turns **on**.
>
> That's it — PipesHub will now start pulling files from S3.
>
> > [!NOTE]
> >
> > Want to connect a second AWS account? Click **+ Add Another Instance** in the top-right and repeat Steps 5–8 with the new account's keys.
>
> ### Step 9: Check that sync is working
>
> Click the instance card to open the **Overview** panel. This shows you live progress.
>
> ![S3 instance Overview panel with Records Status and Records by Type](https://mintcdn.com/pipeshub/WKpUe-DlJrX4Xz-X/images/connectors/s3/instance_panel.png?fit=max\&auto=format\&n=WKpUe-DlJrX4Xz-X\&q=85\&s=e1c4e2e8a3eaed34d351984a03802c7a)
>
> What to look at:
>
> * **Records Status** — the main scoreboard:
>   * **Total** — how many files PipesHub knows about.
>   * **Failed** — files that couldn't be fetched (usually a permission problem in AWS).
>   * **Unsupported** — file types PipesHub can't read (e.g. encrypted or unknown binary).
>   * **Processing** — being indexed right now.
>   * **Not Started** — waiting in the queue.
> * **Records by Type** — shows how many **FILE** records have been synced.
> * **Sync** (top right) — click it to pull the latest changes right now.
> * **Full sync** — click this to re-scan everything from scratch (slower; use only if something looks wrong).
> * **Manage Configuration** — opens the setup panel again if you need to change keys or filters.
>
> If **Total** keeps going up and **Failed** stays at `0`, everything's working.
>
> ## Advanced: Custom IAM Policy
>
> For enhanced security, you can create a custom IAM policy that restricts access to specific buckets or prefixes.
>
> ### Example Custom Policy
>
> Here's a basic example policy for a single bucket:
>
> ```json theme={null}
> {
>   "Version": "2012-10-17",
>   "Statement": [
>     {
>       "Effect": "Allow",
>       "Action": [
>         "s3:ListAllMyBuckets",
>         "s3:GetBucketLocation"
>       ],
>       "Resource": "*"
>     },
>     {
>       "Effect": "Allow",
>       "Action": [
>         "s3:ListBucket",
>         "s3:GetObject"
>       ],
>       "Resource": [
>         "arn:aws:s3:::your-bucket-name",
>         "arn:aws:s3:::your-bucket-name/*"
>       ]
>     }
>   ]
> }
> ```
>
> ### Enhanced Custom Policy (Multiple Buckets)
>
> For production use with multiple buckets and additional permissions, use this comprehensive policy:
>
> ```json theme={null}
> {
>     "Version": "2012-10-17",
>     "Statement": [
>         {
>             "Sid": "VisualEditor0",
>             "Effect": "Allow",
>             "Action": [
>                 "s3:GetObject",
>                 "s3:ListBucket",
>                 "s3:GetBucketLocation",
>                 "s3:GetObjectVersion",
>                 "s3:GetObjectAttributes",
>                 "s3:GetObjectTagging"
>             ],
>             "Resource": [
>                 "arn:aws:s3:::*/*",
>                 "arn:aws:s3:::your-bucket-name-1",
>                 "arn:aws:s3:::your-bucket-name-2",
>                 "arn:aws:s3:::your-bucket-name-3"
>             ]
>         },
>         {
>             "Sid": "VisualEditor1",
>             "Effect": "Allow",
>             "Action": "s3:ListAllMyBuckets",
>             "Resource": "*"
>         }
>     ]
> }
> ```
>
> > [!NOTE]
> >
> > Replace the bucket names in the Resource array (`your-bucket-name-1`, `your-bucket-name-2`, `your-bucket-name-3`) with your actual bucket names. The `arn:aws:s3:::*/*` allows access to all objects in the specified buckets.
>
> **Steps to apply custom policy:**
>
> 1. In IAM, go to **"Policies"** → **"Create policy"**
> 2. Use the JSON editor to paste the policy above (replace `your-bucket-name` with your actual bucket name)
> 3. Name the policy (e.g., "PipesHub-S3-ReadOnly-SpecificBuckets")
> 4. Attach the policy to your IAM user instead of the managed policy
>
> ## Supported Features
>
> The S3 connector syncs the following data from your AWS S3 buckets:
>
> * **Buckets**: All accessible buckets in your AWS account
> * **Files**: All file types with their metadata (name, size, modification date, MIME type)
> * **Folders**: Directory structure and organization using S3 prefixes
> * **Permissions**: Access control based on bucket and object-level permissions
>
> ## Data Sync Behavior
>
> ### Initial Sync
>
> The first sync performs a complete scan of your configured S3 buckets:
>
> * **Bucket Discovery**: Lists all accessible buckets in your AWS account (or uses configured bucket filters)
> * **Region Detection**: Automatically detects and caches the region for each bucket
> * **Full Object Listing**: Fetches all objects from selected buckets using pagination (with a **Folders** filter set to **In**, only the objects in the included folders)
> * **Metadata Extraction**: Extracts file names, sizes, modification dates, MIME types, and paths
> * **Folder Structure**: Creates logical folder structure from S3 object prefixes
> * **Indexing**: Indexes file content for AI-powered search (based on indexing filter settings)
> * **Permission Assignment**: Assigns permissions based on connector scope (Personal or Team)
>
> **Sync Duration Estimates:**
>
> | Bucket Size | Objects | Estimated Time |
> | - | - | - |
> | Small | \< 1,000 | 5-15 minutes |
> | Medium | 1,000 - 10,000 | 15-45 minutes |
> | Large | 10,000 - 100,000 | 1-3 hours |
> | Very Large | 100,000 - 1,000,000 | 3-8 hours |
> | Enterprise | 1,000,000+ | 8+ hours |
>
> > [!NOTE]
> >
> > Use bucket and file extension filters to significantly reduce initial sync time. For example, syncing only PDF files from a specific bucket can reduce sync time by 80-90%.
>
> ### Incremental Sync
>
> After the initial sync, each sync still lists every object in scope (the whole bucket, or each included folder when a **Folders** filter is set to **In**), but downloads and indexes only the ones that changed:
>
> * **Full Listing**: Without a **Folders** filter, each sync lists the whole bucket, page by page. With **Folders** set to **In**, it lists each included folder; with **Not In**, it lists the whole bucket and skips the excluded folders. Listing costs much less than downloading, but its time still grows with the number of objects listed.
> * **Change Detection**: Objects whose `LastModified` is older than the last sync are counted as still present and skipped; new and changed objects are processed.
> * **Sync Point Tracking**: Stores the last sync timestamp per bucket and folder.
> * **Pagination Resume**: Uses continuation tokens to resume an interrupted listing.
> * **Deletions**: After a complete listing of everything in scope, files that are no longer there, and files a **File Extensions** or date filter now leaves out, are removed from PipesHub.
> * **Safe Removal**: If a listing failed, or resumed partway from an earlier interrupted sync, those files aren't removed on that sync, even if the listing reached the last page. The next complete listing removes them.
> * **Narrowed Folders**: Files a narrowed **Folders** filter leaves out are removed on the next sync, even if its listing is incomplete.
>
> **How It Works:**
>
> 1. The connector reads the sync point for each bucket and folder (stored in our database).
>
> 2. It lists the bucket with `ListObjectsV2` (with **Folders** set to **In**, each included folder in turn), following continuation tokens to the last page.
>
> 3. It processes objects that are new or changed since `last_sync_time`, and skips the rest.
>
> 4. It saves the newest timestamp it saw as the next sync point.
>
> 5. After a complete listing, it removes the records of objects the listing no longer returned, and of objects an extension or date filter now leaves out (these are still listed, but skipped before they count as kept).
>
> 6. If the **Folders** filter was narrowed, it also removes the records of files the filter now leaves out, whether or not the listing was complete.
>
> > [!NOTE]
> >
> > Sync time depends on how many objects are listed (the whole bucket, or only the included folders when **Folders** is set to **In**) and how many changed, since only those are downloaded and indexed.
>
> ### Permission Handling
>
> The connector respects AWS IAM permissions and PipesHub access controls:
>
> * **IAM-Based Access**: Only syncs buckets and objects the IAM user has permission to access
> * **Bucket Policies**: Respects S3 bucket policies and access control lists (ACLs)
> * **PipesHub Scope**:
>   * **Personal Scope**: Only the connector creator can access synced content
>   * **Team Scope**: All organization users have read access to synced content
> * **Permission Inheritance**: Files inherit permissions from their parent bucket (Record Group)
> * **Access Control**: Users see only content they have permission to view in both AWS and PipesHub
>
> ### Sync Frequency
>
> **Scheduled Sync:**
>
> * Default interval: 60 minutes
> * Configurable: 15 min, 30 min, 1 hour, 4 hours, 24 hours
> * Runs automatically in the background
> * Best for: Keeping data up-to-date with minimal manual intervention
>
> **Manual Sync:**
>
> * Triggered on-demand from the connector settings
>
> * Best for: Testing, troubleshooting, or syncing after bulk changes
>
> * Useful when: You need immediate sync after uploading many files
>
> > [!NOTE]
> >
> > For large buckets with infrequent changes, consider longer sync intervals (4-24 hours) to reduce AWS API usage and costs.

## Troubleshooting

> **Common Issues and Solutions**
>
> ### Common Issues
>
> **Invalid credentials error:**
>
> *Symptoms:*
>
> * Error message: "InvalidAccessKeyId" or "SignatureDoesNotMatch"
> * Connector fails to initialize
> * Authentication fails immediately
>
> *Solutions:*
>
> 1. Verify Access Key ID and Secret Access Key are correct
> 2. Ensure you copied the full values without extra spaces or line breaks
> 3. Check that the IAM user is active in AWS IAM console
> 4. Verify the access keys haven't been deleted or rotated
> 5. Try creating new access keys if the old ones are compromised
> 6. Ensure credentials are pasted exactly as shown (no leading/trailing spaces)
>
> **Bucket access denied:**
>
> *Symptoms:*
>
> * Error: "AccessDenied" when listing or accessing buckets
> * Some buckets appear but others don't
> * Sync fails with permission errors
>
> *Solutions:*
>
> 1. Verify the IAM user has the following permissions:
>    * `s3:ListAllMyBuckets` - To list all buckets
>    * `s3:ListBucket` - To list objects in each bucket
>    * `s3:GetBucketLocation` - To detect bucket regions
>    * `s3:GetObject` - To download object content
> 2. Check that the bucket policy allows access from your IAM user
> 3. Ensure the bucket exists and is in the same AWS account
> 4. Verify bucket region matches your AWS region configuration
> 5. Review IAM policy JSON to ensure ARNs are correct
>
> **No buckets appearing:**
>
> *Symptoms:*
>
> * Bucket dropdown is empty
> * No buckets available to select
> * "No buckets found" message
>
> *Solutions:*
>
> 1. Check that the IAM user has `s3:ListAllMyBuckets` permission
> 2. Verify credentials are correctly entered in PipesHub
> 3. Ensure the IAM user has access to at least one bucket
> 4. Check AWS CloudTrail logs for permission errors
> 5. Verify the IAM user is in the same AWS account as the buckets
> 6. Try refreshing the bucket list in the filter configuration
>
> **No data syncing:**
>
> *Symptoms:*
>
> * Connector shows "Active" but no files appear
> * Sync completes but no records are indexed
> * Indexing progress stays at 0%
>
> *Solutions:*
>
> 1. Verify the connector status shows "Active" or "Syncing"
> 2. Check that buckets are selected in the filter configuration
> 3. Ensure file extension filters aren't excluding all files
> 4. Verify date filters aren't excluding all files (e.g., "Modified After" set to future date)
> 5. Review sync logs for specific error messages
> 6. Verify the IAM user has `s3:GetObject` permission
> 7. Check that objects exist in the selected buckets
> 8. Ensure indexing filters are enabled (Index Files, Index Folders)
>
> **Sync taking too long:**
>
> *Symptoms:*
>
> * Initial sync runs for hours without completion
> * Progress bar moves very slowly
> * High AWS API usage
>
> *Solutions:*
>
> 1. **Use Bucket Filters**: Sync only necessary buckets instead of all buckets
>
> 2. **Use File Extension Filters**: Filter to specific file types (e.g., `pdf, docx, txt`)
>
> 3. **Use Date Filters**: Sync only recently modified files (e.g., last 6 months)
>
> 4. **Increase Sync Interval**: For large buckets, use 4-24 hour intervals
>
> 5. **Check Bucket Size**: Very large buckets (millions of objects) will take longer
>
> 6. **Monitor Progress**: Check indexing progress to ensure sync is actually running

> > A bucket with 1 million objects can take 6-12 hours for initial sync. Using filters to sync only 10% of objects reduces this to 1-2 hours.
>
> **Region detection errors:**
>
> *Symptoms:*
>
> * Warnings about region detection
> * Sync fails with region mismatch errors
> * Objects not found errors
>
> *Solutions:*
>
> 1. The connector automatically detects bucket regions - this usually works
> 2. If region detection fails, ensure the IAM user has `s3:GetBucketLocation` permission
> 3. Some buckets may require explicit region configuration in AWS
> 4. Check that buckets are in supported AWS regions
> 5. Verify the IAM user has access to the region where buckets are located
>
> **Token expired or sync stopped:**
>
> *Symptoms:*
>
> * Sync was working but suddenly stopped
> * Authentication errors after working previously
> * "Credentials invalid" errors
>
> *Solutions:*
>
> 1. Access keys don't expire automatically, but they can be rotated or deleted
> 2. If access keys were rotated in AWS, update credentials in PipesHub immediately
> 3. Check if the IAM user or access keys were deleted in AWS IAM console
> 4. Re-authenticate by updating credentials in connector settings
> 5. Verify the IAM user still exists and is active
> 6. Check AWS CloudTrail for any credential-related events
>
> **Files not appearing in search:**
>
> *Symptoms:*
>
> * Files synced but not searchable
> * Search returns no results for known files
> * Indexing shows 0% complete
>
> *Solutions:*
>
> 1. Verify indexing filters are enabled (Index Files should be ON)
> 2. Check that file types are supported for indexing (PDF, DOCX, TXT, etc.)
> 3. Images can be content-indexed; check that other file types are supported for indexing
> 4. Wait for indexing to complete - large files take time to process
> 5. Check indexing progress in connector status
> 6. Verify file content is not encrypted or password-protected
> 7. Ensure the file type is supported for content indexing
>
> **Partial sync or missing files:**
>
> *Symptoms:*
>
> * Some files appear but others don't
> * Files in certain folders are missing
> * Inconsistent sync results
>
> *Solutions:*
>
> 1. Check file extension filters - files may be excluded by filter settings
> 2. Verify date filters aren't excluding files
> 3. Check bucket permissions - IAM user may not have access to all objects
> 4. Review sync logs for specific errors about missing files
> 5. Verify files actually exist in S3 (check S3 console)
> 6. Ensure files aren't in excluded buckets (if bucket filter is active)
> 7. Check if files are in Glacier storage class (not directly accessible)

> [!WARNING]
>
> If you rotate or change AWS access keys, you must update the configuration in PipesHub immediately. The connector will fail to sync until new credentials are provided.

## AWS S3 Compatibility

This connector is designed for **Amazon S3** and uses the AWS S3 API. It supports:

* **All AWS S3 Regions**: Works with buckets in any AWS region worldwide
* **Standard S3 Storage Classes**: Standard, Standard-IA, One Zone-IA, Intelligent-Tiering
* **S3-Compatible Services**: Should work with MinIO and other S3-compatible storage (with proper endpoint configuration)

**Not Supported:**

* S3 Glacier and Glacier Deep Archive (requires restore process)
* S3 Outposts (may require special configuration)
* Requester Pays buckets (not currently supported)

> [!NOTE]
>
> The connector uses the standard S3 API and should work with S3-compatible services like MinIO, but is primarily tested and optimized for AWS S3.

## FAQ

> **How long does the initial sync take?**
>
> The initial sync duration depends on the size of your S3 buckets:
>
> | Bucket Size | Estimated Time |
> | - | - |
> | Small (\< 1,000 objects) | 5-15 minutes |
> | Medium (1,000 - 10,000 objects) | 15-45 minutes |
> | Large (10,000 - 100,000 objects) | 1-3 hours |
> | Very Large (100,000 - 1,000,000 objects) | 3-8 hours |
> | Enterprise (1,000,000+ objects) | 8+ hours |
>
> **Tip**: Use bucket and file extension filters to significantly reduce initial sync time. For example, syncing only PDF files from specific buckets can reduce sync time by 80-90%.

> **Can I sync multiple AWS accounts?**
>
> **No**, each connector instance connects to a single AWS account. To sync buckets from multiple AWS accounts, you'll need to:
>
> 1. Create separate IAM users in each AWS account
> 2. Create separate S3 connector instances in PipesHub
> 3. Configure each connector with credentials from the respective AWS account
>
> This allows you to manage and filter buckets from different accounts separately.

> **What file types can be indexed for search?**
>
> The connector can index supported file types for AI-powered search:
>
> **Supported:**
>
> * Documents: PDF, DOCX, XLSX, PPTX, ODT, RTF
> * E-books: EPUB, unless copy-protected (DRM); searchable, but not previewable
> * Text: TXT, MD, CSV, JSON, XML, HTML
> * Code: Python, JavaScript, TypeScript, Java, Go, and many others
> * Images: JPG, PNG, GIF, WebP
>
> **Not Supported:**
>
> * Videos: MP4, AVI, MOV, etc.
> * Audio files
> * Archives: ZIP, RAR, TAR, etc.
> * Password-protected files
> * Binary files without supported content extraction
>
> Supported images can be content-indexed for AI-powered search.

> **How does incremental sync work?**
>
> After the initial sync, each sync works like this:
>
> 1. **Lists Everything in Scope**: Lists every object in the bucket, or in each included folder when a **Folders** filter is set to **In**
> 2. **Skips Unchanged Objects**: Objects not modified since the last sync are counted as present and not downloaded again
> 3. **Processes Changes**: Downloads and indexes only new or modified objects
> 4. **Removes Deletions**: After a complete listing, removes files that are no longer there
> 5. **Updates Timestamp**: Saves the newest timestamp for the next sync
>
> Skipping unchanged objects is what makes later syncs faster than the first. The listing itself still covers everything in scope.

> **Can I sync S3 Glacier files?**
>
> **No**, the connector does not directly support S3 Glacier or Glacier Deep Archive storage classes. These storage classes require a restore process before files can be accessed.
>
> If you need to sync Glacier files:
>
> 1. Restore the files to Standard storage class in S3
> 2. Wait for restoration to complete
> 3. The connector will then sync the restored files
>
> Consider using S3 Intelligent-Tiering or Standard-IA for frequently accessed files that need to be searchable.

> **What happens if I delete a file in S3?**
>
> The file's record and search index entries are deleted from PipesHub on the next sync that lists everything in scope from start to finish without an error (the whole bucket, or each included folder when a **Folders** filter is set to **In**). The file then no longer appears in search results.
>
> If a listing fails, or resumes partway from an earlier interrupted sync, the file isn't removed on that sync, even if the listing reaches the last page. The next complete listing removes it.
>
> **Note**: S3 versioning doesn't keep a deleted file visible. Once the current version is a delete marker, the listing no longer returns the key, so the file is removed.

> **Can I sync encrypted S3 buckets?**
>
> **Yes**, the connector supports S3 buckets with encryption:
>
> * **SSE-S3**: Server-side encryption with S3-managed keys (fully supported)
> * **SSE-KMS**: Server-side encryption with AWS KMS keys (requires KMS permissions)
> * **SSE-C**: Server-side encryption with customer-provided keys (not supported)
> * **Client-side encryption**: Files encrypted before upload (not supported)
>
> Ensure your IAM user has the necessary KMS permissions if using SSE-KMS.

> **How do I sync only specific folders in a bucket?**
>
> Add a **Folders** filter with the folder's path from the bucket root, for example `reports`, and set it to **In**. Subfolders are included. Set it to **Not In** to sync everything except that folder.
>
> If you change the folders later, files the filter now leaves out are removed from PipesHub on the next sync.
