user23 Posted December 13, 2007 Report Share Posted December 13, 2007 Hi, I recently moved my RAID to a new host computer. I changed the host in Retrospect and selected the same volume, but Retrospect is not recognizing that there are already snapshots on the tape that belong to that volume and it is copying everything. I need to do this same process for about 2 terrabytes of data, so I'd rather not copy over the entire thing new. Any suggestions? Thank you!

rhwalker Posted December 13, 2007 Report Share Posted December 13, 2007 It's a different host and different volume to Retrospect. There is no way to get it to recognize a moved volume of which I am aware. Sorry. Put in a feature request. I have never seen a feature request be implemented, and I've been using Retrospect for about 15 years. Heck, I haven't seen some of the show-stopper bugs fixed in years. Good luck.

Mayoff Posted December 13, 2007 Report Share Posted December 13, 2007 Something about the data looks different to Retrospect, forcing the files to be copied again. Retrospect does not care what disk the data is located on. Retrospect looks at the Name, size, creation date and time, kind, label and metadata. If any of this is different, the files get copied again. Link to comment Share on other sites More sharing options...

We're back to the discussion of whether or not you think that the way Retrospect tracks volumes is a feature or a bug. I think it's a feature, as it's the safest and most fault tolerant method. But Mayoff is right; if the files are the same, Retrospect will match them to what's already in the Backup Set and not copy them again, although it _will_ need to go through the entire (new) volume and construct a Snapshot you can use for future Restores of this volume. Is it actually copying files to tape? You might want to pre-flight a backup, then compare some files in the Browser against the same files already in the Backup Set (from the Reports->Contents window). Perhaps you'll see if/how the files differ in this new configuration. Dave Link to comment Share on other sites More sharing options...

I think it's a feature, as it's the safest and most fault tolerant method. I agree that it's the safest method, and I have no complaint. The cost of my tapes is insignificant compared to the value of my data. Other people may differ and may want some sort of a preference. Everything you said is dead-on correct, Dave. Diana, you might also want to check your "matching" options on your backup set's script (Options > Matching). Russ Link to comment Share on other sites More sharing options...
