I am using rsync to keep a mirror of my 800GB /home (server1). The backup machine is a separate server (servr2). Currently I am running rsync daemon on server2 and invoking rsync daily via cron on server2. Are there design / performance considerations that influence which machine is made the server and which the client? Also, Is the rsync daemon the preferred way to o this backup? I can also

I had a recent disaster scenario with rsync. I was wondering if there were any suggestions to guard against in the future: I used to maintain "mirror" backups of the /home dir on our production_server using rsync to a backup_server. The primary server had a rsyncd daemon running and the backup_server had this line in the crontab: 10 01 * * * rsync -av --delete root at

Is there a way to speed up rsync by opening more than one daemon in parallel. I use rsync --daemon to start rsync. I was wondering if opening more than one instance is recommended or feasible? I know that for services like nfs for example I have had opening many instances improve performance. I have 4 cores available so if there are any other parallization modes I'd be glad to know since I

I cannot figure out where I am going wrong with my excluded files syntax! rsync backups up those folders I'm trying to exclude. rsync -av --exclude-from=/etc/rsync_excluded.conf --delete root@polaris::polhome /pol_home_bkup cat /etc/rsync_excluded.conf - /home/agokhale - /home/anand - /home/asalazar etc. These are all top level folders with the same names. On the rsync server

While trying to find a strategy to avoid duplicating renamed files and folders I came across threads about a "dtetect-renamed" option. This was a patch back in 2006 but I cannot find much about it later. Was this aborted? Are there any other ways of smart-ly detecting renames? -- Rahul

Is there a way to set rsync excludes by filesize? I already do excludes by a wild card on the name but I needed something a bit more sophisticated this time around. I have files with the extension .nc (netcdf files) which tend to be huge before the users post-process them. I want all files with a .nc extension excluded if they are, say, 100+ MB in size. Is there a way to do this via rsync?

Is there a way to know from the rsync logs how long it took to do a backup? The only timing info,. I see is this at the end: sent 3067328 bytes received 7853035429 bytes 1187888.83 bytes/sec total size is 1559866450336 speedup is 198.55 Can I use it to figure out how long the operation took? Does the above mean it took 2.5 secs of send time and 1.8 hours of recieve time so (roughly) the
