Backup

Automatic backup of photos to a secondary location

CaptureGRID can automatically copy each downloaded photo to a secondary backup location. This provides a layer of redundancy that protects against accidental deletion or disk failure at the primary download location.

Backup is configured per-node and operates on photos as they are saved. Each node maintains its own backup independently of the others, which makes the backup feature orthogonal to the GRID networking feature described in Networking — they protect against different kinds of failure and are typically used together.

Backup Window

The Backup window shows the current backup configuration and the status of recent backup activity.

Note

Screenshot pending — Backup window showing the configured backup destination and a list of recently backed-up photos.

From this window you can monitor:

  • The current backup destination(s)

  • The most recent backup operations

  • Any errors or warnings (for example, if the backup location is full or unreachable)

Configuration

Backup destinations and behaviour are configured from the Options window. See the backup-related fields under the relevant Options tab.

When the backup is enabled, each photo that is saved to the local Photo Download Folder is also copied to the configured backup location. The copy happens automatically and asynchronously, so the download itself is not blocked waiting for the backup to complete.

Tip

A common configuration is to set the backup destination to a different physical disk from the primary download folder. This means a single disk failure cannot lose both copies.

For more critical capture scenarios, the backup destination can be a network shared folder, in which case the photos end up on another machine altogether.

Relationship to GRID Networking

Backup and GRID networking both provide protection against losing photos, but they work at different levels:

  • Backup is per-node and copies each photo to a secondary location on the same network. It is concerned with redundancy of the photo file itself.

  • GRID networking synchronises photo information across all nodes on the network, and (when Sync photos is enabled) also transfers the photo files to other nodes. See Photo Transfers for the details.

The two features are independent — backup runs whether or not GRID is enabled, and GRID’s photo transfers run whether or not backup is configured. Many setups use both: GRID to gather all photos onto a central node, and backup on that central node to provide a redundant copy of the aggregated photo set.
