There was an article in the Spectrum magazine not to far back about just this subject. If you look at this link you can find the article. It has a step by step procedure for implementing backup with rsync. http://www.intlspectrum.com/DesktopModules/Repository/MakeThumbnail.aspx?tab id=73&id=33
We use it to backup about 36 gigs every night from and AIX server to a Linux backup server, it only takes about 10 minutes when the database is active, and the database in only off line for a couple of seconds. Shown below is the log file from our process. rsync of koidb began at 02:00:00 on 09/04/06. Suspension of file updates is active Snapshot for file system /koidb created on /dev/dbbkuplv Suspension of file updates is inactive UniVerse was back online at 02:00:02 on 09/04/06. rsync of koidb finished at 02:03:27 on 09/04/06. rsync of koiprogs began at 02:03:27 on 09/04/06. rsync of koiprogs finished at 02:03:29 on 09/04/06. # This is not a very active system, but this shows the process. We actually have a system where we keep disk images of the backup for the last 7 days, the last 5 Fridays, and the last day of the month for 13 months. All of this is available down to the field level.

At present we use rcp after first putting the source data in read-only (dbpause) mode. But this copies every file regardless of whether any changes have been made. I think rsync copies changed files either by comparing datestamps and file size, or doing block checksum comparison. We copy about 60GB down a long 300km fibre 10M/bit pipe which takes 30 hours, so doing a 'changed blocks' only rsync process would save a lot of time.
