Resume Backup
If a backup job fails due to interrupted connection to the backup repository, Veeam Agent will perform a backup job retry. During retry, instead of restarting data transfer from the beginning, Veeam Agent will try to resume the backup process from the point where it was interrupted.

If for some reason, after the connection to the backup repository is restored, the APFS snapshot is no longer available, Veeam Agent will trigger the creation of a new snapshot. Then Veeam Agent will compare the modification times of the files in the new snapshot and on the target repository. In the backup repository, Veeam Agent will replace all files that have mismatching modification timestamps with their latest versions from the newly created snapshot. |
- If the data to back up resides on a volume with any supported file system excluding APFS, Veeam Agent performs the backup of such data in the snapshot-less mode. In this case, after the connection to the repository is restored, Veeam Agent will compare the modification times of the files in the source file system and in the target repository. In the backup repository, Veeam Agent will replace all files that have mismatching modification timestamps with their latest versions from the source file system.
Consider the following limitations of Resume Backup:
- Resume Backup is initiated during a retry of a scheduled backup job only. If you start the backup job manually and Veeam Agent loses connection to the target repository during backup, after the connection is restored, Veeam Agent will remove the incomplete restore point and create a new restore point.
- Resume Backup is disabled for backups to local and directly attached storage repositories.
