[BackupPC-users] Feature request: preserve (from deletion) individual backups by number

[Jeffrey J. K. <bac...@ko...>]

In general, using FullKeepCnt and IncrKeepCnt (and associated
variables) works well to prune older backups.

But sometimes there is a *specific* older backup that you want to hang
onto because it has some crucial data (or is a 'better' snapshot). It
would be great if you could tell BackupPC to keep an arbitrary list of
numbered backups for each different host. (If any of the listed backups
are incrementals, then BackupPC would of course be smart enough to
save the relevant precedent incrementals and full backups).

For example I could imagine, a perl hash of arrays of the following
form:

$Conf{PreserveBackups} = {
		"hostA" => [ '23', '354', '798' ],
		"hostB" => [ '3', '25', '37', '101' ],
		"hostC" => [ '9', '11', '33', '434' ],
		};

Does this make sense?
