Key Capabilities
- Amazon S3 and S3-compatible service integration (Google Storage, Wasabi) with IAM role and access key authentication
- Bucket-based file organization with bidirectional transfers and prefix-based virtual folders
- Client-side and server-side encryption options with configurable access policies
- Optional caching to ensure only new or updated files are downloaded
Overview
Each S3 connector can automatically upload to and download from a single S3 bucket. Before you begin, you need an Amazon account with the appropriate credentials (or account credentials for the S3-like service you are using). Specify the upload and download paths in the bucket. The connector supports download filters by file name.Connector Configuration
This section contains all of the configurable connector properties.Settings Tab
Host Configuration
Settings related to the remote connection target.Account Settings
Settings related to the account with permission to access the configured Bucket Name.TLS Settings
Settings related to TLS negotiation with the S3 server.Upload
Settings related to the path in the specified bucket where files are uploaded.Download
Settings related to the path in the specified bucket where files are downloaded.Caching
Settings related to caching and comparing files between multiple downloads.Arc automatically cleans up the resource cache. This process runs in the background during every receive cycle and removes stale cache entries for files that are no longer present on the remote server. This keeps the cache size manageable without requiring any manual action.
By default, files are retained for 30 days, but you can use the ResourceCacheRetentionDays setting in the Other Settings field on the Advanced tab to adjust it to fit your environment. For example, ResourceCacheRetentionDays=15 retains files for 15 days before removing them.

Advanced Settings
Settings not included in the previous categories.Proxy Settings
These are a collection of settings that identify and authenticate to the proxy through which the connection should be routed. By default, this section uses the global settings on the Proxy Settings portion of the Security Settings page. Clear the checkbox to supply settings specific to your connector.
| Setting | Description |
|---|---|
| Proxy Type | The protocol used by a proxy-based firewall. |
| Proxy Host | The name or IP address of a proxy-based firewall. |
| Proxy Port | The TCP port for a proxy-based firewall. |
| Proxy User | The user name to use to authenticate with a proxy-based firewall. |
| Proxy Password | A password used to authenticate to a proxy-based firewall. |
| Authentication Scheme | Leave the default None or choose from one of the following authentication schemes: Basic, Digest, Proprietary, or NTLM. |
Message
Message settings determine how the connector searches for messages and manages them after processing.
Note: The settings below are deprecated and hidden by default. They appear only on connectors where they were previously enabled or configured to a non-default value. To retain copies of successfully processed files, right-click the connector in the flow, choose Show Success Path, and connect the success path to a File connector.
| Setting | Description |
|---|---|
| Save to Sent Folder (Deprecated) | Copies files processed by the connector to the Sent folder. Disabled by default. Files saved to the Sent folder are not covered by Encryption at Rest. |
| Sent Folder Scheme (Deprecated) | Groups files in the Sent folder by the selected time interval. Only relevant when Save to Sent Folder is enabled. |
Logging
Settings that govern the creation and storage of logs.
| Setting | Description |
|---|---|
| Log Level | The verbosity of logs generated by the connector. When you request support, set this to Debug. |
| Log Subfolder Scheme | Instructs the connector to group files in the Logs folder according to the selected interval. The Weekly option (which is the default) instructs the connector to create a new subfolder each week and store all logs for the week in that folder. Leaving this setting blank tells the connector to save all logs directly in the Logs folder. For connectors that process many transactions, using subfolders helps keep logs organized and improves performance. |
| Log Messages | Check this to have the log entry for a processed file include a copy of the file itself. If you disable this, you might not be able to download a copy of the file from the Transactions tab. |
Miscellaneous
Miscellaneous settings are for specific use cases.
| Setting | Description |
|---|---|
| Other Settings | Enables you to configure hidden connector settings in a semicolon-separated list (for example, setting1=value1;setting2=value2). Normal connector use cases and functionality should not require the use of these settings. |

Performance
Settings related to the allocation of resources to the connector.
| Setting | Description |
|---|---|
| Max Workers | The maximum number of worker threads consumed from the threadpool to process files on this connector. If set, this overrides the default setting on the Performance Settings portion of the Advanced Settings page. |
| Max Files | The maximum number of files sent by each thread assigned to the connector. If set, this overrides the default setting on the Performance Settings portion of the Advanced Settings page. |

Establishing a Connection
The requirements for establishing an S3 connection are simple:- Amazon account credentials (or other S3-like account credentials)
- Access Key
- Secret Key
- A bucket that can be accessed by the above account
Uploading
Upload to Remote Folders
The Prefix setting in the Upload section of the Settings page specifies the bucket path to upload files to. This allows for the logical separation of files into virtual folders in the same bucket.S3 servers do not maintain a real folder structure, and Arc uses application logic to present a pseudo folder structure. Slashes in the Prefix (
/, \\) are interpreted as representing a folder hierarchy. This allows for uploading to or downloading from ‘subfolders’ in the bucket based on the slashes in the path.Upload Automation
The S3 connector supports automatic upload via the Automation tab. When Upload automation is enabled, files that reach the Transactions tab for the connector are automatically uploaded to the specified Bucket Name at the specified Prefix. If a file fails to upload, the application attempts to send it again after the Retry Interval has elapsed. This process continues until the Max Attempts has been reached, after which the connector raises an error.Downloading
Download from Remote Folders
The Prefix setting in the Download section of the Settings page specifies the bucket path to download files from. This allows for the logical separation of files into virtual folders in the same bucket. The File Filter setting provides a way to only download specific filenames in the specified path.S3 servers do not maintain a real folder structure, and Arc uses application logic to present a pseudo folder structure. Slashes in the Prefix (
/, \\) are interpreted as representing a folder hierarchy. This allows for uploading to or downloading from ‘subfolders’ in the bucket based on the slashes in the path.
