- Description
- ~~~~~~~~~~~
- The prune command prunes a repository by deleting 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.
- As an example, "-d 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 hourly to yearly, and backups selected by previous
- rules do not count towards those of later rules. The time that each backup
- completes 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-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.
- 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!
