[pbs-devel] [PATCH 0/5] backup validation improvements

First patch skips server-side validation (existance check) of last snapshot's
chunks if the base was verified successfully at least 7 days ago. With verify
scheduling this means that users can avoid the overhead during backups by doing
weekly verifications.

The latter 4 patches (marked RFC, not sure if the idea is that sound) make the
validation happen in a seperate thread. This requires some modifications to
ParallelHandler and carries the tradeoff that we have to verify *all* chunks of
the last backup, since when the thread starts we don't know yet which ones the
client will upload and overwrite anyway.


proxmox-backup: Stefan Reiter (5):
  backup: don't validate chunk existance if base was recently verified
  ParallelHandler add unbounded mode
  ParallelHandler: add check_abort function and handle errors during
    join
  ParallelHandler: exit early if this or other thread aborted
  backup: validate chunk existance in background
