for offsite backups, we hope to snapmirror our new fas 3020 on a regular schedule via vpn over the internet to an older filer at our colo. obviously, intermittent latency is a concern since we don't have a dedicated link. and so is the potential for overpowering the modest firewall/network hardware currently in place. does anyone have a suggestion for how we might throttle the snapmirrors to improve reliability in the transmission?
and how are you folks handling encryption for remote mirroring? we have a small pix, sonicwall, or cisco to choose from...i'm guessing we may have to try all three but i hope to pick the one most likely to succeed the first time.
