Description
~~~~~~~~~~~
Documentation: Explicate that Fnmatch is default This fixes #1247. It also regenerates the usage documentation, so that styling fixex in that section (as well as other existing changes) make it into the files in docs/.
2016-07-03 14:27:02 +00:00
The prune command prunes a repository by deleting all archives not matching
update man pages / usage docs
2018-07-12 20:00:19 +00:00
any of the specified retention options.
Important: Repository disk space is **not** freed until you run ``borg compact``.
This command is normally used by automated backup scripts wanting to keep a
build_usage
2022-01-23 14:52:21 +00:00
certain number of historic backups. This retention policy is commonly referred to as
`GFS <https://en.wikipedia.org/wiki/Backup_rotation_scheme#Grandfather-father-son>`_
(Grandfather-father-son) backup rotation scheme.

Merge branch '1.0-maint'
2016-07-05 23:33:53 +00:00
Also, prune automatically removes checkpoint archives (incomplete archives left
behind by interrupted backup runs) except if the checkpoint is the latest
archive (and thus still needed). Checkpoint archives are not considered when
python setup.py build_usage
2017-06-17 10:28:42 +00:00
comparing archive counts against the retention limits (``--keep-X``).
Merge branch '1.0-maint'
2016-07-05 23:33:53 +00:00
If a prefix is set with -P, then only archives that start with the prefix are
considered for deletion and only those archives count towards the totals
specified by the rules.
Otherwise, *all* archives in the repository are candidates for deletion!
ran build_usage had merge conflicts in the usage files, decided to just recreate them afterwards.

There is no automatic distinction between archives representing different
contents. These need to be distinguished by specifying matching prefixes.
Merge branch '1.0-maint'
2016-07-05 23:33:53 +00:00
If you have multiple sequences of archives with different data sets (e.g.
from different machines) in one shared repository, use one prune call per
data set that matches only the respective archives using the -P option.

The ``--keep-within`` option takes an argument of the form "<int><char>",
where char is "H", "d", "w", "m", "y". For example, ``--keep-within 2d`` means

to keep all archives that were created within the past 48 hours.
"1m" is taken to mean "31d". The archives kept with this option do not
count towards the totals specified by any other options.

A good procedure is to thin out more and more the older your backups get.
python setup.py build_usage
2017-06-17 10:28:42 +00:00
As an example, ``--keep-daily 7`` means to keep the latest backup on each day,
Merge branch '1.0-maint'
2016-07-05 23:33:53 +00:00
up to 7 most recent days with backups (days without backups do not count).
The rules are applied from secondly to yearly, and backups selected by previous
rules do not count towards those of later rules. The time that each backup
starts is used for pruning purposes. Dates and times are interpreted in
the local timezone, and weeks go from Monday to Sunday. Specifying a
build_usage
2021-02-06 00:32:02 +00:00
negative number of archives to keep means that there is no limit. As of borg
1.2.0, borg will retain the oldest archive if any of the secondly, minutely,
hourly, daily, weekly, monthly, or yearly rules was not otherwise able to meet
its retention target. This enables the first chronological archive to continue
aging until it is replaced by a newer archive that meets the retention criteria.
Merge branch '1.0-maint'
2016-07-05 23:33:53 +00:00
python setup.py build_usage
2017-06-17 10:28:42 +00:00
The ``--keep-last N`` option is doing the same as ``--keep-secondly N`` (and it will

2016-07-05 23:33:53 +00:00
keep the last N archives under the assumption that you do not create more than one

backup archive in the same second).
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 pruning.
