ChronoSync

ChronoSync is a simple backup and file-syncing program for Mac computers that keeps your important files safe and up to date. It automatically makes copies of your photos, documents, and folders so you never lose them if your computer crashes or gets stolen. It quietly watches for changes and copies only the new or updated files to keep everything current without you having to lift a finger. ChronoSync uses affordable S3-compatible object storage as its backup destination, treating these cloud buckets like an unlimited external hard drive that lives safely off-site. This S3 connection gives you rock-solid protection, easy access from anywhere, and automatic versioning so you can recover older file versions if you ever need them.

Connection / Setup

  1. Create an account and log in to DiskSpace
  2. Click I'm ready to set up my storage
  3. Enter Bucket Name following the instructions
  4. Click Create Bucket and wait for it to be generated
  5. Find your Endpoint URL, Access Key, and Secret Key in the S3 Client Configuration section for use below

Connecting ChronoSync to DiskSpace.sh (S3-compatible storage)

DiskSpace.sh provides fully S3 API compatible storage. Follow the steps below to configure ChronoSync using path-style requests.

Connection Steps:
  1. Open ChronoSync and create a new Cloud Connection or edit an existing one.
  2. Select Amazon S3 (or S3 Compatible) as the storage provider.
  3. Enter the following connection details:
Endpoint URL
Required. Use this exact endpoint.
Access Key
Provided by DiskSpace.sh
Secret Key
Provided by DiskSpace.sh
Region: Leave blank or set to us-east-1
Important: Path-Style Requests

DiskSpace.sh requires path-style URLs (not virtual-hosted style). ChronoSync must be configured to use this format:

Example URL format:
https://s3.diskspace.sh/bucket-name/key
Configuration Tip: In ChronoSync's advanced S3 options, ensure "Use Path Style" or "Force Path Style" is enabled. This is critical for successful connections to DiskSpace.sh.
Example Configuration
Endpoint: https://s3.diskspace.sh
Access Key: AKIAXXXXXXXXXXXXXXXX
Secret Key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Region: us-east-1 (or leave empty)
Path Style: Enabled
Troubleshooting
  • Connection fails: Verify you are using path-style requests and the exact endpoint shown above.
  • "Signature mismatch" error: Confirm region is set to us-east-1 or left blank.
  • Access denied: Double-check that your Access Key and Secret Key are entered correctly.
  • Still having issues? Ensure no trailing slashes are added to the endpoint URL.
