Not necessarily, don't mix capacity with speed. A 2 link Port-Channel is still 2 x 1 Gbs link. If the backup is between only 2 IP (not multiplexing backup from multiple sources), the Port-Channel algorithm will still give you only 1 Gbs per IP pairs or port pair, etc. You have to check the load-balancing option of the Port-Channel in your system. There is multiple algorithm available to load-balance in the Port-Channel. You have to chose the correct one for your system.

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 [email protected] with the body: unsubscribe ntsysadmin ~ 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 [email protected] with the body: unsubscribe ntsysadmin ~ 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 [email protected] with the body: unsubscribe ntsysadmin ~ 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 [email protected] with the body: unsubscribe ntsysadmin
