It reall depends on the number of files and the size for rsync. On a decent box, I can run through 400 files in not even a second. Figure out your rate of change by doing some sample rsync's of X mail dirs and multiple it out.
100 mbit is kinda slow, gig-e at least between the rsync box and the filer might be obtained even cheaply by a crossover cable on a private ip network for just the rsync's.

Hello,
I need to replicate data between a FAS250 and non-NetApp storage - I can't warrant another Filer at the moment, so SnapMirror is out sadly.
The amount of data will be just under 1TB and will contain Maildirs, so the level of change will be quite high for about 300GB of that. The rest will be fairly static.
The connection used for replication will be 100Mbit/sec. I'd like to find a method that can get me as close to immediate replication as possible, however a lag of about 3 hours is probably acceptable for most of the content.
I've been looking at the file server extension to NDMPv4 and various third-party software, as well as things like rsync, but wondered if anyone else had any ideas of things I should be looking at?
Thanks in advance,
