I've just released version 0.26 of Obnam, my backup application. The relevant part of NEWS:

  • Clients now lock the parts of the backup repository they're using, while making any changes, so that multiple clients can work at the same time without corrupting the repository.
  • Now depends on a larch 0.28, which uses journalling to avoid on-disk inconsistencies and corruption during crashes.
  • Compression and encryption can now be used together.
