Well, that all depends on how many changed blocks you expect in a day, as well as what kind of link you have, how busy the link is currently, what exact model of PIX or Sonicwall you have, and what the operating hours of the business are.
Snapmirror does include a throttle, but if you throttle it too much, you'll be perpetually behind. And if you don't throttle it enough, it's about the same as not having one. It might be possible to do your snapmirror overnight, if it's acceptable to your client, and not throttle it at all. There are really a lot of options here.

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.
