My sysadmin says, I cannot have multiple session of tar on a LTO tape.
Is this true ?
If the answer is yes, how can we accomplish that without buying a 3rd
party software. Basically, I want to tar a 20 GB file to a 200GB tape
today and tar another 20GB tommorrow to the same tape (add i mean) and
so on.

Whats the solution to this ?

Thanks
