You haven't specified your backup method, but I'll make a couple of assumptions: * you are using rsync over SSH If your 800G file server is taking 24 hours per backup, there are probably some optimisations you can make. Firstly, check if either your backup server or file server are consuming all available memory and swapping during the backup. Adding some extra RAM will drastically reduce the backup time. The other issue is the size of the files on your fileserver, lots of small files will take longer than lots of small files. Other than that, you can look at IO etc on both fileserver and backup server. Probably your bigger fileservers are faster, but you backup server is only so fast... Examine where the bottlenecks are, and then you can either remove/improve those bottlenecks, or else add additional backuppc servers (if the backup server is the bottleneck and removing it is too costly). Gotta go, hopefully someone else will add some other suggestions.
