[Veritas-bu] DLT7000 Speed
2001-10-18 13:57:34
Benr,
I would say it's pretty good speed for backups with compression
working on client side.
If you don't use compression the speed is low.
I don't see much reasons to turn compression on client side,
saving network traffic is not so big issue.
For me backups w/o compression take twice less time then with it.
