Tony Albano Posted May 12, 2014 Report Share Posted May 12, 2014 Hi I'm using Retrospect 8.5.0. I've noticed that when running a Duplicate backup set as "replace if source is newer" the backup copys a lot more files than have actually changed. As a result, the backup takes a lot longer than it should. Only this morning, I know that only one file had changed but the activity window showed multiple files being duplicated - something like 6.5GB. The file that had changed is only 58MB!! Any idea why this is happening? Thanks AA Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted May 12, 2014 Report Share Posted May 12, 2014 What is the source and destination in this case? Both are local drives connected to the Retrospect server computer? One is a Retrospect client computer and the other a network share? http://retrospect.com/en/support/kb/retrospect-wants-to-re-copy-unchanged-files-during-a-backup 1 Quote Link to comment Share on other sites More sharing options...
Lucky_Phil Posted May 13, 2014 Report Share Posted May 13, 2014 It could be duplicating files that were accessed, not just altered. However, if you are backing up your own files, you may find that the speed of duplication is faster by turning off a few options. I find the following settings makes for faster duplication: (see screen capture) Check to see if you have turned off - in Security Settings - save file security. Turning off save file security settings can make the duplication job run much faster. Quote Link to comment Share on other sites More sharing options...
Tony Albano Posted May 13, 2014 Author Report Share Posted May 13, 2014 Thanks for your replies. The source is a NAS drive and the target is a USB-attached drive. Most of the security settings are the set the same as you've shown. I'll try the suggestion in the KB article. Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted May 14, 2014 Report Share Posted May 14, 2014 The metadata will most likely be different on a NAS, compared to a local drive. We had a dual boot client the other year. It had three disks: XP, Vista and Data. When booting in XP all three disks were fully backed up. When booting in Vista all thre disks were fully backed up again. No file-deduplication at all. The same hardware, the same client version, the same server and the same media set. Quote Link to comment Share on other sites More sharing options...
