That depends how fast the network you're running is, and how much data you've got to worry about, and maybe other things. Gigabit Ethernet can stream 125,000,000 8-bit quantities per second. Framing and protocol overhead rob significantly from that. Let's assume 75% efficiency, just to have a number. That's 93 megabytes per second, or 337 gigabytes in one hour. If you're only backing up a terabyte, that might be just fine. If you're backing up a petabyte, not so much. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe ntsysadmin
