Cache, or information obtained from the security directory is newer than repository - this is either an attack or unsafe (multiple repos with same ID)

Something broke during a backup, try (re)moving ~/.config/borg/security/<id> and ~/.cache/borg/<id>.

 

Prune: Chunk ID missing from chunks index, corrupted chunks index - aborting transaction.

Try

borg check ( --repair )

If check finds no problem, delete cache:

mv ~/.cache/borg ~/.cache/borg_corrupted

ValueError: stats_against: key contained in self but not in master_index.

Try

Rename repository

  • On server: rename repository
  • On client: change previous_location in ~/.cache/borg/*.config
  • BORG_RELOCATED_REPO_ACCESS_IS_OK=yes
