I find that transfers to/from the NSLU2 over ethernet run at an
acceptable speed, obviously slower that direct hard drive - hard
drive. Never had any problems with crashing (using LanMan98).

I also use the caddy system. Some tips are to quit SparkFs (or
whatever is your archiver/dearchiver), which prevents the copy
process going into zips etc. Also quit all apps that are unnecessary,
since open files can be a problem. One tip here is to check !Run
files of any running apps to ensure there are no spurious line feeds
at the end, which cause the !Run file to be kept open until the app
is quit.
I found that David Pillings SyncDiscs is more susceptible to machine
hangs due to its non-multitasking nature. I have converted to using
!DirSync, which does multitask during the backup. It generally
requires more user intervention, but has a wide range of options for
what to copy and not to copy etc. It also has an option to not look
into archives so you can leave SparkFS running.

Yes - mine sound like a jumbo jet taking off! The other problem
(certainly with mine) is that the Iyonix must be powered down to
either insert or remove a caddy drive. I normally have the caddy
empty (mainly because of the noise), so a backup requires a
shutdown/restart, which is an additional 'hurdle' when you are
working on various projects, and normally leave the machine running
24/7. I know also that some users of Iyonix (not me fortunately) have
problems with powering up and rebooting.
