I plan to use rsync to sync data from second to first server. It is OK ? Any suggestion ?

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.

There is also rdiff-backup if you need history. Of course it is not a perfect solution either. Any solution is going to have trade offs.
