[pve-devel] [PATCH v2 manager 13/13] Always use prune-backups instead of maxfiles internally

[Fabian Ebner]

For the use case with '--dumpdir', it's not possible to call prune_backups
directly, so a little bit of special handling is required there.

Note that $opts->{'prune-backups'} is always defined after new()
