rsync doesn't much tolerate network glitches in my experience. its also a incremental file backup/copy, and won't be doing a 'snapshot' so if any of these files you're copying are things that are randomly updated like a database, its quite possible for the copy to be useless.
as a backup strategy, having a single copy that you overwrite when you make a new copy is weak. you have no history, you can't recover the file that the user overwrote 2 days ago and forgot to tell you until today, as you just overwrote your backup with his mistake last night.
it really depends on what the point of this replica is, what the usage patterns are, what the data archive expectancies are.
What do you suggest for scheduled incremental saves of files changing irregularly ?
