thanks, i am compressing everything in the server because i'm backing up some windows nt clients mounted by samba (smbmount) in my tape server. If i use compress in clients instead the server, the compress of the nt clients will be done by the machine where i have mounted the nt client????.
At this moment i've enough space, i'm usinf 40 Gb hp surestore dats, and my amount of data isn't very large. But in the future, maybe i need compress in clients......
