Not sure if anyone mentioned this yet, but you might want to have a look at a product called BackupPC, which is based on rsync but puts a really nice front end on it.
Not sure if it can work over SSH though. Just read the fine manual to find out.
Yes, backuppc can work with or without ssh - and besides hard-linking the identical files it also compresses them.
May be anyone using Clustring metode an improving DRBD and HA for this case?
That's a somewhat different scenario. Backuppc and other hardlink backup tools maintain a history with snapshot copies at configurable intervals so you can restore things even if you don't notice a problem until later. DRBD is a live replication of only the current contents. If, for example, someone accidentally deletes your source code repository or an important database, it would be gone immediately on the copy too.
