i'm wondering about grooming under version 10. as a preface, i will say that i could never really get grooming to work the way i wanted it under versions 8 (where i mostly didn't experiment much due to a variety of other problems and issues) and version 9 (where my experiments met with poor results leaving me thinking that i must be doing something fundamentally "wrong" in terms of how the program was designed to work). my simplistic starting assumption is that with grooming, retrospect should be able to work somewhat like the way time machine does in that you could allocate some storage to it, let it start backing up and it would save everything (every version, every incremental backup, etc.) until it ran out of space, and then when the allocated space was depleted, it would start deleting the oldest, unused stuff to make way for new stuff. with a modest number of machines (3-4) and what seemed to me to be a modest number of backups (roughly 2x/week for a few months), i would find that my media sets would take a really really long time to groom (like ~3-4 days) under version 9. so now i've installed version 10 and i'm trying it out. my first attempt is to groom an existing media set with 1TB of storage and a few million files. so far it's been running almost 5hrs. as with previous versions, there are NO meaningful progress indicators of any kind during grooming, which is quite frustrating (edit: see followup note below about progress reporting). but if i had to guess, i would say that version 10 does not look like it is going to provide any kind of huge improvement. the web page describing mac version 10 says "IMPROVED! Automatic Disk Grooming Tell Retrospect how many backups to keep, and it will automatically remove older backups when it needs more space on disk-based storage. This technology allows Retrospect to perform faster, smaller Smart Incremental backups forever." this sounds like exactly what i'm looking for. questions: is there something i need to do in order to see this "improved" behavior and in particular to see faster grooming? for example, do i need to create new media sets? is there some kind of first-time cost when v10 reads v9 catalogs before this wonderful new feature kicks-in? any other advice on how to get "smart incremental backups forever" w/o having to recycle backup sets and hopefully without needing multi-day groom operations?
