If your backup destination runs out of space then backups to that destination will simply stop. CrashPlan will not automatically delete backed up data in order to make room at the destination.
In order to resolve the situation you’ll need to perform one of the following actions:
- Option 1: Add more disk space to the destination
- Option 2: Select fewer files to back up or change the retention settings
- Option 3: Run Compact on the destination to prune any data that shouldn’t be backed up anymore
Option 1: Add Storage
If you are backing up to a local folder, consider increasing the amount of available space in the destination filesystem.
If you are backing up to an external drive, consider replacing the drive with a larger device. You could also consider rotating drives.
If you are backing up to an external network device, consider allocating additional storage to the NFS or iSCSI share.
If you are backing up to another server on your network, consider increasing the amount of available space in the destination filesystem or migrating the filesystem to a new location (Settings > Backup > Inbound Backup > Default Backup Archive Location) .
Option 2: Adjust Retention Settings

- After changing the retention settings, you will need to manually Compact the destination (see below)
Option 3: Compact or Maintain Archive
See also: CrashPlan PRO Wiki: FAQ: What happens if my backup destination runs out of space?
Archive maintenance involves cleaning up the backup archive to remove backed up data according to the retention settings you’ve specified. Archive maintenance removes:
- File versions that are too old
- Deleted files that no longer need to be kept
- Files that are no longer selected for backup
- Self-heal archive blocks that have become corrupted (re-requests those blocks from the client).
A user can perform a manual archive maintenance by clicking the Compact button in PRO Client for a specific destination.
- Within your client, de-select the file/folder you want to remove
- Click Destinations and then select the appropriate destination type (Computers or Folders.)
- Click the specific destination
- Click the Compact button
NOTE: Removing files from your backup selection permanently removes the files from the backup archive. After compacting, de-selected and old data will be removed in the remote destination. You will not be able to restore any de-selected or old data once the maintenance/compact process is complete.
