Retrospect duplicating already duplicated files!

[finisterre]

Hi,

 

I'm using Retrospect Professional 7.5 to backup my Xp Pro PC to a NAS box.

 

Earlier today I backed up an entire drive to the NAS for the first time using IMMEDIATE DUPLICATE/REPLACE ENTIRE DISK. It successfully backed up the 320GB on my 1TB D: drive with no errors.

 

I've just run it again to backup a few changed files, and after the scan it has decided it wants to backup up 200GB again and is now in the process of doing so.

 

I used to use Retrospect Express to backup to external USB/Firewire drives with these options and this never happened.

 

Where am I going wrong?

 

Thanks.

Duplicate is copying files, not backup. Duplicate / replace entire disk is cloning, a special type of copying files that first wipes out the destination, but still not a backup (which would preserve history).

Either do a backup ("normal") rather than a duplicate, or keep doing duplicate (not backup) but don't replace the entire disk.

Thanks, but correct me if I'm wrong, REPLACE ENTIRE DISK if supposed to do the following:

 

"Replace Entire Disk deletes all files and folders on the destination which do not match those marked for duplication, leaving files untouched if they are identical to files marked. It then duplicates remaining files and folders from the source, preserving the folder hierarchy."

 

 

And whenever I've used it in the past is has worked this way.

Just doing some testing on a subset of the data.

 

It appears that Retrospect is deleting all the previous copied files in the destination volume (although leaving the empty directory structure intact) and then copying everything again.

 

This is NOT how the REPLACE ENTIRE DISK option used to work when I used to backup to regular external HDD drives. It used to just copy new/changed files and remove deleted files.

 

I can only assume my new NAS is not processing the file modification dates/other attributes properly on the NAS once it has copied the files over.

 

Any ideas?

Just tried again on an old Firewire external drive.

 

1st run - copies all the data.

2nd run - copies nothing 'cos it's already there.

 

So it appears to be a NAS-related issue.

 

Any ideas?

 

Thanks.
