IIUC both ZFS and btrfs require that you be root to work with file system snapshots.

  On Btrfs an unprivileged user can create subvolumes/snapshots. There's a mount option that lets them remove subvolumes they own.

    I didn't know that. Very cool!

  Solaris has a fine-grained privilege model where you can delegate any aspect of any dataset to any user. However, FreeBSD and Linux don't have this, so on those systems you have to be root to do snapshots.

    Ah, I see. I've only used ZFS on FreeBSD so I guess I'm missing out. Thanks.
