hi, sorry this is older thread but just fyi, ive been using Mozy with my Gen1 4-slot drobo and its been ok with all the options ticked.
(what i did notince in the past was that it can take a while and slow things down if i use its default “backups sets” - because it takes ages trying to scan the whole drives for files that match it’s default sets.
(with those disabled, its been working fine for 35k files across a mixture of sizes, icon clipart libraries, digipics, samples, and multimedia productions etc) (35,000 files of about 17GB total) - aprt from the odd message glitch or when wireless plays up, its been fine over here.
one think you could try is to make 1 new folder in your root drobo, put a few files into it, and then go up a level (back to root) and rightclick on the new folder choosing Add To Mozy Backup.
then when you go inside that folder and refresh, it should show you the icons to show that its planned for, but not yet included in, the next backup run.
as far as i know, if you modify one of those files, or if you add something to the folder, Mozy “should” detect it and inlclude it in the next run (and you can always manually initiate a run).
If the 1 folder trick works, (maybe if you do end up having some files open/locked, you could try removing your backups sets and just setting it up on that 1 folder) - or to have several of those main backup folders which you can use in this way.
just some thoughts/info from my usage and experience :)[hr]
