at some places, the docs were not updated yet. for borg 1.x, -a (aka --glob-archives) expected sh: style glob patterns ONLY (but one must not give sh: explicitly). for borg 2, -a (aka --match-archives) defaults to id: style (identical match), so one must give sh: if one wants shell-style globbing.

Examples
|
|
~~~~~~~~
|
|
|
|
Be careful, prune is a potentially dangerous command, it will remove backup
|
|
archives.
|
|
|
|
The default of prune is to apply to **all archives in the repository** unless
|
|
you restrict its operation to a subset of the archives using ``-a`` / ``--match-archives``.
|
|
When using ``-a``, be careful to choose a good pattern - e.g. do not use a
|
|
prefix "foo" if you do not also want to match "foobar".
|
|
|
|
It is strongly recommended to always run ``prune -v --list --dry-run ...``
|
|
first so you will see what it would do without it actually doing anything.
|
|
|
|
::
|
|
|
|
# Keep 7 end of day and 4 additional end of week archives.
|
|
# Do a dry-run without actually deleting anything.
|
|
$ borg prune -v --list --dry-run --keep-daily=7 --keep-weekly=4
|
|
|
|
# Same as above but only apply to archive names starting with the hostname
|
|
# of the machine followed by a "-" character:
|
|
$ borg prune -v --list --keep-daily=7 --keep-weekly=4 -a 'sh:{hostname}-*'
|
|
# actually free disk space:
|
|
$ borg compact
|
|
|
|
# Keep 7 end of day, 4 additional end of week archives,
|
|
# and an end of month archive for every month:
|
|
$ borg prune -v --list --keep-daily=7 --keep-weekly=4 --keep-monthly=-1
|
|
|
|
# Keep all backups in the last 10 days, 4 additional end of week archives,
|
|
# and an end of month archive for every month:
|
|
$ borg prune -v --list --keep-within=10d --keep-weekly=4 --keep-monthly=-1
|
|

There is also a visualized prune example in ``docs/misc/prune-example.txt``:
