Ok, trying to make a backup to sdb, but fsarchiver just gives an error message:
:~$ sudo fsarchiver -v -jn -zn -a -A savefs /dev/sdb1/xubuntu_backup.fsa /dev/sda1
fsarchiver.c#202,process_cmdline(): [n] is not a valid number of jobs. Must be between 1 and 32
====> fsarchiver version 0.6.17 (2013-02-25) - http://www.fsarchiver.org <====
What's wrong with my command now..? Tried to google it, but no hits.
