> borg is "the holy grail" of backups as it does everything rsync always did I tried borg for some time for full backups from / and there were 3 things I didn't like about it: 1. Mounting and navigating a snapshot was extremely slow. Like wait a few seconds for any `ls` to finish. 2. It needed the encryption password for many things I think it shouldn't. 3. The resulting backups are very opaque. I've since switched to making my backups by rsync'ing to btrfs subvolumes. I snapshot the previous backup and rsync the differences to the new one. I get to navigate each snapshot with the same snappiness as any other directory in the filesystem. btrfs can also instantly tell me which files differ between 2 snapshots, no matter how huge they are. I don't remember all the options that borg offers on synching, but I doubt it has the same breadth of options as rsync. So for me, rsync + COW filesystem > borg. I am a little concerned with my use of btrfs, but I'm planning to do the same thing using ext4's reflinks for some disk and filesystem redundancy.
