colletti Posted August 15, 2007 Report Share Posted August 15, 2007 How would we completely eliminate a directory from our backups on disc? We have been backing up one directory redundantly in two different backup scripts and we would like to remove all traces of it to free up space, from one of the backup scripts. We have removed the directory from the Client Sources list in the Volumes tab. We then ran a groom which freed up quite a bit of space but not as much as we though it would. However the snapshots are still present. If we "Forget" about these snapshots will it free up more room? Thanks. Link to comment Share on other sites More sharing options...
Lennart_T Posted August 16, 2007 Report Share Posted August 16, 2007 How much did the directory contain? (in Megabytes) How much data was groomed? (in Megabytes) The files will not be groomed out until the last snapshot containing the files is removed (either manual or part of the grooming process). So yes, forgetting the snapshots will groom the files out. But why not just wait? The files will be groomed out eventually as long as you keep backing the client/disk up and you groom regurlarly.

colletti Posted August 16, 2007 Author Report Share Posted August 16, 2007 Thanks for your reply. The original directory is right around 300GB. The groom operation removed approximately 100GB. This directory in question is on a linux server but is also mounted on our windows file server so it was being backed up twice all along (full backups of both the linux server and that partition on the windows server). Now we need more space on one of our backup partitions and this is when we discovered the redundant backups of that directory. I will forget the snapshots and run another groom as you say. thanks.

No, it wasn't backed up twice if the files were identical. That's they beauty of Retrospect: Identical files are backed up ONCE, regardless of the number of copies laying around on any number of computers. So that explains why only 100GB was groomed. "Retrospect uses several matching criteria to find new or changed files. If one of the criteria has been changed, Retrospect will back up the file again. On Windows, Retrospect looks at creation date and time, modified date and time, size and name. If match only in same location option is set, Retrospect matches on the path, volume name and drive letter also. "By default, the archive attribute is not used as a matching criteria in Windows, allowing for true and reliable backups to multiple backup sets."

colletti Posted August 17, 2007 Author Report Share Posted August 17, 2007 So even though this partition was being backed up in two completely different backup scripts and being stored on two different disc partitions, retro was aware and did not backup the data up twice?

Lennart_T Posted August 17, 2007 Report Share Posted August 17, 2007 No, that's not what I meant. I mean that any file is backed up once per backup set. (The number of scripts is not relevant.) I didn't realize you had more than one backup set. Anyway, keep backing up and grooming normally and the duplicate files will be groomed out eventually (since the new backups don't include them).
