I always feel funny playing cheerleader, but there have been a couple Gobbler related posts lately, so let me chime in.
I pestered the snot out of the Gobbler folks when they released it for Mac... I wanted my Windoze version. When they released a Winders version I wanted Sonar integration... they probably don't like me much, but I now have Sonar integration, so I'm happy<G>!
I do not know if I was the first Sonar user to try Gobbler, but I was a very early adopter. There have been a couple minor hiccups along the way, but I can say, with complete confidence, that I am a very happy user! I can't imagine not using Gobbler for my studio backups. It's just too easy... and how often does one make that observation?
With the release of X3 there is a minor problem with projects being backed up again if you re-save them in X3. You could, I suppose, look at this as an extra layer of version control, but since Gobbler already handles versioning it probably isn't necessary. Although the first time I need to re-open a project in X2 I guess I'll have to eat some crow.
I don't, presently, do a lot of transfers, but I think that's one of the cooler features. Actually, all the features are cool - automated backups, version control, transfers, de-duplicating, it's all really useful.
On top of that I have found the Gobbler developers to be very helpful.
I can't recommend Gobbler highly enough.
