# storeBackup.pl --sourceDir /home/user --backupDir /tmp/my_backup_destination
# Its slow the first time because it compresses all files bigger than 1k (default setting)
# The backup tool is bookkeeping which files got compressed
# btrfs warning: you may run out of hardlinks soon
# known impurity: test cases seem to bu using /tmp/storeBackup.lock ..
