Please try version 0.1.7 where I have added some tweaks which may avoid these errors.
Ok 0.1.7 works great except for one small thing, it is not removing the /media/backup directory when it finishes.
It seems it is not unmounting and rmdir the /media/backup directory. No errors in the log file though
Did you ask it to? I didn't make any changes myself to allow for a setup like yours.
Well, that'd explain it!
Thanks! That sorted it and the backup now boots. Great stuff!
