I recently bought a used Drobo (Gen. 2) to replace my old Gen 2 Drobo that died after the power supply shorted and burned the circuits in the enclosure. While I would have liked to upgrade to a newer model, I don’t have the funds currently, so I had to settle for another Gen 2 to be able to keep the data on my disk pack. Now, the sudden demise of the old Drobo left the drives a bit unreliable, so I have backed up all the data and reformatted the entire Drobo disk pack.
Now for the question: What are the current thoughts on using a Drobo Gen. 2 as a Time Machine backup? When I bought my original Drobo, I formatted it to use 4 TB volumes, and chose one as my Time Machine drive. However, later i read tips on using Sparse Images and the Time Tamer app. At that time I had no interest in switching my approach, but now that I’m beginning fresh, I’d like to examine the alternatives. I really don’t need 4 TB of Time Machine backups (2 TB will do), and as my old TM backup grew I felt that it became incredibly sluggish and perhaps even affected the performance of the Drobo in general.
The problem is that the Gen 2 is now outdated and I’m having trouble finding any articles on this in the KB. Some advice would be great! Do I let Drobo Dashboard partition my disk pack into 2 TB volumes, should I create a .sparseimage in some way or use Disk Utility to partition a 2 TB drive from a 16 TB Drobo volume? Or something else I haven’t thought of?
I’m using Yosemite on an iMac (late 2012) with a 1 TB Fusion drive, and my Drobo has 4 x 2 TB drives.
