Additional archiving considerations

Successful (green) backups and backups that ran with warnings (yellow) are eligible for archiving. Failed (red) backups are not archived.

You must select at least one client and backup type or one local directory to create an archive set.

Note:  Navigation groups do not display in the Clients to Archive list. If you wish to archive based on a navigation group, select the group in the Navigation pane to display only the clients in the selected group.

To archive backups successfully, the media must have adequate storage space.

An archive job for which purge or overwrite has been selected fails if purging or overwriting cannot create adequate space for the job. When archiving without the overwrite or purge option and adequate space is not available, archives are appended to any existing archive sets until the media is full. For details, see How archiving uses available space on media.

Unitrends system metadata is archived in each set. In the event of a system failure, you can use this archived metadata to restore the Unitrends system configuration, schedules, and other settings. (You see System Metadata File listed under sets for backups and archives.)

Note:  On tape archiving - Disaster recovery from tape archive is not supported.

For each client in an archive schedule, incrementals are synthesized into a differential. This synthesis only occurs for clients that are in an archive schedule. Synthesis does not run for on-demand archives, although on-demand jobs do contain synthetic differentials if the incremental/differential backup type is selected.

If you attempt to archive a backup that has already been written to the media, it is not written to the media but other backups in the job are archived. The original backup remains intact with the original archive date.
