# Goal: Emulate encrypted Time Machine backups from a Mac to a Linux system
#       with rsync 'snapshotting' + encfs. This provides an additional backup
#       to a Linux based filesystem like ext4 just in case of HFS+ issues as
#       described here: http://blog.barthe.ph/2014/06/10/hfs-plus-bit-rot/
#       This is not expected to solve all potential bitrot scenarios - rather
#       to provide some redundancy and make detection easier (with additional
#       scripting effort).
