bamaral Posted October 11, 2006 Report Share Posted October 11, 2006 I am using Restrospect MultiServer 7.5.5.103 to backup about 520GB at the moment on the local server it's installed on which is a Dell PE2650 w/dual 2.4GHZ Xeons and 4GB of ram. I am backing up one partition that contains all our artwork, the 2nd partition has software and data, and the 3rd is the local C: drive. The backup performance never goes over let say 275.0 and that's being generous & the backups are taking about 20 hours to complete. How can I get the performance to increase? What I did notice is that when I have a completed .rbf backup file I can backup that single file to LTO3 with much better performance aroud 1500.0. That's fast, so why is backing up to disk so slow?

Lennart_T Posted October 11, 2006 Report Share Posted October 11, 2006 Backing up a lot of small files is much slower than backing up a single file with the same amount of data (in MB). How many files do you have and how much space do they use. "Backing up TO disk"??? Didn't you backup to tape? Link to comment Share on other sites More sharing options...
bamaral Posted October 11, 2006 Author Report Share Posted October 11, 2006 Mon-Fri I back up to disk & on Sat I back up to tape. I backup the root C:\ which has 18,522 files and takes up 5.88GB, next is the D:\ which has 174,013 files takes up 114GB then the F:\ which has 617,454 files and takes up 340GB. This is done after hours so no one has open files while it's running. It should be getting faster backup performance than in the 250.0 range, right? I have it set to backup the individual folders containing the data within those partitions so the only partition that gets backed up completely is the root.

Lennart_T Posted October 12, 2006 Report Share Posted October 12, 2006 That is right, you SHOULD be getting faster backup. Here's data from me, backing up two clients to AIT-2 tapes: Client A: 339763 files, 99.9GB data, 354 MB/min Client B: 277279 files, 6.1 GB data, 94 MB/min You are closer to Client A than B in terms of average file size.
