Description
|
|
~~~~~~~~~~~
|
|
|
|
The prune command prunes a repository by deleting all archives not matching
|
|
any of the specified retention options. This command is normally used by
|
|
automated backup scripts wanting to keep a certain number of historic backups.
|
|
|
|
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
|
|
comparing archive counts against the retention limits (``--keep-X``).
|
|
|
|
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!
|
|
There is no automatic distinction between archives representing different
|
|
contents. These need to be distinguished by specifying matching prefixes.
|
|
|
|
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.
|
|
As an example, ``--keep-daily 7`` means to keep the latest backup on each day,
|
|
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
|
|
negative number of archives to keep means that there is no limit.
|
|
|
|
The ``--keep-last N`` option is doing the same as ``--keep-secondly N`` (and it will
|
|
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. |
