I am a freelance 3D illustrator and animator, and I generate a massive amount of content. I have a Mac Pro Hexacore with 4 x 1TB internal drives, and 2 x 2TB external drives, for a total of 8TB of storage. I also have another Mac Pro with a single 1TB internal drive, a PowerMac with a single 1TB internal drive, and a MacBook Pro.
Originally, the external drives were back-up drives, but they've started to fill up with original files, because I'm running out of storage on the internal drives. It's time to build a new backup system, and I'm looking for tips.
I'm thinking about getting a Drobo 5N enclosue with 5 x 3TB internal SATA drives. That will give me 10.9 TB of backup capacity with single disk redundancy (8.2 TB if I go with dual disk redundancy). That should be enough to back up all my computers, even if they're full, which they're not....yet.
This will cost me about $1400, so no chance of getting 2 systems for redundancy. I'm counting on the built-in redundancy of the Drobo system.
So...my first question is: any other thoughts on hardware solutions?
Next, software. I'm looking at either Carbon Copy Cloner or SuperDuper. I've had a problem with Carbon Copy Cloner in the past....a couple years ago. I made a sparse image of a disk, and some time later the original disk failed. When I installed a new disk and went to recover from the sparse image, I discovered that the sparse image only contained about 1/3 of the data on the original disk. The rest was lost. So, I've got trust issues with CCC.
I've never used SuperDuper.
Any thoughts on software solutions? And thoughts in general?
