[pbs-devel] [RFC PATCH proxmox-backup] tape: single snapshot restore

[Dominik Csapak]

this is a first version of a possible single snapshot restore from tape
some small parts are in-progress/unfinished:
* api path is (imho) not optimal, but did not find something better
  (integration into existing restore call gets ugly fast...)
* schema for the snapshot list is not done yet (but not hard..)
* no parallelization (also not done yet for normal restore)
* some things could probably be better refactored
* gui for multiselection is not done yet (have to think about how
  we do that for a good ux)

questions to answer:
 do we really want to have the ability to restore multiple 'single' snapshots
 in one go? if not, it would drastically simplify the code

Dominik Csapak (7):
  tape/drive: add 'move_to_file' to TapeDriver trait
  tape/media_catalog: add helpers to look for snapshot/chunk files
  api2/tape/restore: factor out check_datastore_privs
  api2/tape/restore: make datastore in restore_snapshot_archive optional
  api2/tape/restore: add 'restore-single' api path
  bin/proxmox-tape: add restore-single command to proxmox-tape
  ui: tape: add single snapshot restore
