AndrewM Posted July 21, 2007 Report Share Posted July 21, 2007 Can I use Retrospects Multiple Executions ability to backup several sources to a single NAS server simultaneously? Will this increase the speed of my backups? Do I risk any sort of data corruption? Will Retrospect even allow this? I am saving all backups to a 1.3TB RAID5 NAS running NASLite-2, but a ~50GB backup has been running for about 15 hours so far and Retrospect estimates another 22-26 hours for completion! Granted alot of the slowness is probably due to me neglecting to turn off compression and verification, but still.. how can I speed this up? Also, while I'm on the subject, the help file under Multiple Concurrent Executions says "Retrospect allows you to: change configuration settings while and operation is executing;" Does this mean that I can modify my script while it is running to disable file compression and verification? If so, how? The help file doesn't seem to make any further reference to modifying configuration settings during execution. :EDIT: I restarted the backup with verification and compression turned off and I'm still getting only around 20MB/min. I expected more like 9 MB per *second* or around 500MB/min. Why so slow? Quote Link to comment Share on other sites More sharing options...

But you need a separate Backup Set for each script running at the same time. We do run NAS servers here and ran two scripts to the same server. We changed this so the scripts are now scheduled to use one NAS server at a time, but we didn't see any (real) speed boost.

Yikes! We do get around 300-400MB/min per script, running 2 scripts simultaneously. Almost every time we have slowdowns like yours, it has been the Network Interface Card driver that needed updating. In one instance, it was the actual wall outlet in an office. Quote Link to comment Share on other sites More sharing options...
