Comment 4 for bug 1652975

I'm merging the features of Timeshift BTRFS into Timeshift so that users
can select between Rsync and BTRFS snapshots. It will take few weeks to
finish and test the changes.

BTRFS snapshots will be the better option for docker as it does not
duplicate files and creates a perfect copy of the file system.

Thanks,
Tony
