rsync really slow
by danabooth from LinuxQuestions.org on (#6M3ZD)
I looked around for answers, and I did find a lot of folks bitchin about the speed of rsync, but no real solutions. We have a fileserver, not very big, current usage is ~1.7TB. I made a new fileserver using Debian 12 running Samba .. I mounted the old fileserver in /mnt and cifs, and let rsync copy the files over, it took three days. Now you'd think that after that, I could run rsync and since pretty much everything is here, it would take a few minutes, but it takes about four hours. The command is:
rsync -rqu --size-only --delete --log-file=<file> <src> <dest>
I've really not used rsync much in the past outside of small cron jobs at home, can anyone shed light on what I'm doing wrong, or is rsync just that slow?
As a side note, I also back up that same (old) file server with my windows work computer using robocopy.exe to an external usb spinner, and the backup takes about 7-10 minutes every hour, there's just not that much going on on that particular server.
