HI,
We use a Quantum tape library and Sony DLT IV tapes to back up our data. I've noticed that say nearly all the tapes will have a different compression ratio. Even on our full backup jobs, which span multiple tapes, the compression ratio varies. Eg, for our full Netware backup, the first tape might have 45GB on it, the next might have 60GB on it and the next may have up to 90GB on it. Is there a reason for this?
Thanks
