This command deletes archives from the repository.

Important: When deleting archives, repository disk space is not freed until you run borg compact.

When in doubt, use --dry-run --list to see what would be deleted.

When using --stats, you will get some statistics about how much data was deleted - the “Deleted data” deduplicated size there is most interesting as that is how much your repository will shrink. Please note that the “All archives” stats refer to the state after deletion.

You can delete multiple archives by specifying a matching pattern, using the --match-archives PATTERN option (for more info on these patterns, see borg help patterns).

Always first use --dry-run --list to see what would be deleted.


# delete a single backup archive:
$ borg delete Monday
# actually free disk space:
$ borg compact

# delete all archives whose names begin with the machine's hostname followed by "-"
$ borg delete -a '{hostname}-*'

# delete all archives whose names contain "-2012-"
$ borg delete -a '*-2012-*'

# see what would be deleted if delete was run without --dry-run
$ borg delete --list --dry-run -a '*-May-*'
