Environment: Desktop with Win XP Pro SP3, Retrospect Pro 7.7.620, nightly local FILE backup to USB drive, two 1TB BU drives with one off-site, swapped regularly. I recycle the BU sets when the BU disks fill up, approximately once a year. This Retrospect BU strategy has worked well for at least 10 years now, with successful file recovery many times and system recovery twice. I had previously stayed away from DISK backups, but don't remember why (perhaps support of DISK backups in earlier versions wasn't that robust?), and I understand that over the last several years the whole concept and support of DISK backup sets has improved, so now that type of backup is recommended over a FILE backup, even with my 7.7 level. Perhaps I'm sort of stuck in the past and need to rethink this FILE vs. DISK strategy. That concern really came to my attention a few weeks ago when my on-site backup, then several hundered gigabytes in size, became corrupted for unknown reasons. It was not recoverable; I had to recyle it and start over. I just started using a DISK backup for my new laptop, and notice that it consists of many files instead of a single large file with the FILE backup. I suppose that is what makes it groomable? So I am strongly considering going to a DISK backup strategy for my desktop. But I have a few questions that I haven't been able to answer through Retrospect support of this forum. 1. In the instance above, would I have potentially avoided the corruption of my entire backup if it were a DISK backup? Losing one or more of these smaller backup file would have cost me what? 2. In my environment, is one backup type fundamentally more desirable than the other? Advantages/disadvantages of each? 3. The "grooming" concept is a bit difficult for me to understand, not having done it. When I groom, will I still have a complete system backup to restore from, a backup that is simply missing some of the sessions, or nightly backups, in the larger backup? Or will I have to exercise caution when I groom to make sure that I am not ending up with a partial backup, one that would not allow me to do a full system restore to, say, last night's image?
