tar backup on tape in linux

Typical use:

backup: tar -clpzvf /dev/st0 /dir1 /dir2 /dir3
compare: tar -dlpzvf /dev/st0 /dir1 /dir2 /dir3
restore: tar -xlpzvf /dev/st0 /dir1 /dir2 /dir3

For multiple tapes just add the -M option:

tar -clpMzvf /dev/st0 /dir1 /dir2 /dir3
tar -dlpMzvf /dev/st0 /dir1 /dir2 /dir3
tar -xlpMzvf /dev/st0 /dir1 /dir2 /dir3
