Tar is probably right to complain about some things.  Try to understand 
them - they may or may not be important.  Rsync is meant to copy 
disk-disk, perhaps over a network, but it isn't going to work with tape.

Tar should work fine for this.  You could automate with amanda or 
bacula, but for a single host it is probably easier to just schedule the 
tar commands.

That's normally not a problem other than getting whatever state you 
happen to catch in an active file.
