Rollback To A Working State With btrfs + apt-btrfs-snapshot On Ubuntu 12.10 This tutorial explains how you can revert failed apt operations (like apt-get upgrade) and roll back to the previous system state with apt-btrfs-snapshot on an Ubuntu 12.10 system that uses the btrfs file system. apt-btrfs-snapshot creates a snapshot of the system before the apt operation. Being able to easily restore the previous system state after a failed apt operation takes away much of the pain system administrators have to deal with normally and is one of the greatest features of the btrfs file system. in Public bookmarkswith aptapt-btrfs-snapshotbtrfsrollbacksnapshotubuntu
