[pve-devel] [PATCH storage 0/6] partially fix #2649: Introduce prune-backups for storages supporting backups

[Fabian Ebner]

What's still missing is to use this setting when executing backups
as we do with 'maxfiles' at the moment, and also GUI integration.

archive_info has been extended to include more information, mainly
for being able to tell when a backup doesn't use a standard name.
But the information might be useful elsewhere as well.

I also included a few tests and updated the archive_info tests.

Non-standard backups are ignored when pruning. I chose 'protected'
to mark those, 'ignore' could also be used.

The information from directory-storage backups and from PBS
backups don't fully match up, e.g. I created volid for PBS
by using backup group + ctime and translate backup type
ct->lxc, vm->qemu, so that the possible values don't depend
on the backend.

Regarding the API endpoints: there's a regex below '{storage}/content',
namely '{volume}', so it's not possible to create endpoints like
'{storage}/content/prunebackups'. Instead, I introduced '{storage}/prunebackups'.

Fabian Ebner (6):
  PBSPlugin: list_volumes: filter by vmid if specified
  Expand archive_info to include ctime, vmid and is_std_name
  Introduce prune-backups property for directory-based storages
  Add prune_backups to storage API
  Whitespace cleanup
  Add API and pvesm calls for prune_backups
