How to resolve the archive error: Retention policy of archive sets on target media prohibits overwrite.
If you are seeing the archive error: 'Retention policy of archive sets on target media prohibits overwrite', you have run an archive with the Overwrite option checked and one or more existing sets on the archive media cannot be deleted due to retention rules. All existing sets must be eligible for deletion to use the Overwrite option. If any archive set on the media is not eligible for deletion, overwrite is not allowed and the archive fails. For more information, see the following sections in the Unitrends Administrator's Guide:
To resolve this error, do one of the following:
- Run the archive without the Overwrite option to append the new set to sets already on the media.
- Run the archive without the Overwrite option and use the Purge option instead, to remove only the sets that are eligible for deletion (those that have no retention setting or those for which the retention period has elapsed).
- Prepare the archive media to force removal of ALL existing sets on the drive, then run the archive. USE CAUTION AS THIS REMOVES ALL EXISTING SETS, REGARDLESS OF RETENTION SETTINGS.
