I too have set up Time Machine and Drobo using the sparse image procedure w/firewire 800 connection. I’m using Snow Leopard OS on a MacPro. Time Machine seems to be backing up just fine, but the inability to see the prior backups with Time Machine is disturbing to say the least. Strangely there are now two “disks” on the desktop, one labelled Time Machine (the Drobo) and the other labelled “TM-backup-of-”, the former contains the sparse bundle file and the latter contains the folder “Backups.backupdb” with all the incremental backups within. Have I missed a post that explains this and offers help in recovering files?
I have yet to find someone who describes how to recover prior states or prior files if needed. One poster suggested that there is a bug in the “software”, but I don’t know whether the finger is pointing at Apple or at Data Robotics to fix the problem. Surely one of their software engineers is listening, no?
Drobo at times acts like Pontius Pilate, with their disclaimers. If most people are purchasing a Drobo (like me) for backup purposes only you would think they would be more helpful than to offer “use at your own risk” statements. I bought the Drobo for backup and to simplify my life, not complicate it. I’d much sooner worry about the CONTENT of my backed up files and not the technical details of my computer and backup system.
Data Robotics could significantly enhance their sales if they could begin to get glowing, unqualified recommendations from their current owners. I’m spending far too much time on this, and lose sleep over my less than full confidence in the Drobo solution. Someone talk me down on this!!
