When I'm running an
rsync backup job which involves copying over large files, the machine running the backup (both Mac desktops and Linux servers) grinds to a halt and the load average goes through the roof.
rsyncprocess (doesn't help - the bottleneck is the disk)
- On Linux,
kjournald(helps, but seems like a hack and doesn't work on the Mac)
- Using the
rsyncflag (helps, but it means all the transfers are slow - even when they don't need to be)
So, is there any way I can "
rsync's IO so the machines are useable while the backup is running?
PS: I'm aware of the dangers of
rsync on the Mac… But I've used BackupBouncer to verify my backups, though, and they seem OK.
