# Host muse has a pair of RAIDs, one each for audio and video,
# and a dedicated disk for backups (/var/cache/rsnapshot),
# which other hosts remote mount via sshfs.
# NOTE:	We clone *all* our own local audio and video to the RAIDs
# NOTE:	the rsnapshot process requires root level access permissions,
#	therefore the rsnapshot volume must be mounted as root,
#	which therefore, via sshfs, leaves it invisible to non root users,
#	(e.g. the 'df' command run by regular user does not show it).
#	Regular users can still recover files from backups via:
#	rsync -auvzH muse:/var/cache/rsnapshot/hourly.0/.sync/`hostname`/home/`whoami`/myfile ~
#	or do their own sshfs mount as themself to some mount point.
