prune

usage: borgmatic prune [--repository REPOSITORY] [-a PATTERN] [--stats]
                       [--list] [--oldest TIMESPAN] [--newest TIMESPAN]
                       [--older TIMESPAN] [--newer TIMESPAN] [-h]

Prune archives according to the retention policy (with Borg 1.2+, you must run
compact afterwards to actually free space)

prune arguments:
  --repository REPOSITORY
                        Path of specific existing repository to prune (must be
                        already specified in a borgmatic configuration file),
                        quoted globs supported
  -a PATTERN, --match-archives PATTERN, --glob-archives PATTERN
                        When pruning, only consider archives with names,
                        hashes, or series matching this pattern
  --stats               Display statistics of the pruned archive [Borg 1 only]
  --list                List archives kept/pruned
  --oldest TIMESPAN     Prune archives within a specified time range starting
                        from the timestamp of the oldest archive (e.g. 7d or
                        12m) [Borg 2.x+ only]
  --newest TIMESPAN     Prune archives within a time range that ends at
                        timestamp of the newest archive and starts a specified
                        time range ago (e.g. 7d or 12m) [Borg 2.x+ only]
  --older TIMESPAN      Prune archives that are older than the specified time
                        range (e.g. 7d or 12m) from the current time [Borg

  --newer TIMESPAN      Prune archives that are newer than the specified time
                        range (e.g. 7d or 12m) from the current time [Borg
