Over the weekend, my 1 TB Time Capsule seems to have failed, after only 16 months or so – the power light won’t even come on, and I suspect a power supply failure.
This is forcing me to reevaluate my data storage and backup strategy.
First of all, I will never, ever, again buy a disk storage unit that does not have an easily removable disk drive, so that if the enclosure fails, I can easily move the data to another device. As it stands, if I take the Time Capsule into Apple for maintenance, their employees will have access to both my public and private data, even if it was just a power supply failure.
Now, I don’t have anything that is sensitive on that drive, much less anything illegal or even inflammatory, unless you consider my tax records for 1998 particularly salacious. It just violates my sense of privacy. Nonetheless, I really don’t like the thought of someone browsing through my data, looking for possible porn or other gems. And now, if I decide I want to prevent such snooping, I have to drill holes right through the Time Capsule, ruining the enclosure, as well as the disk drive.
I believe that I need three different forms of data recovery.
The first is a form of journaling, that permits me to undo an “oops” if I screw up and delete a file that I really needed, or want to revert back to a previous state.
The second is a backup mechanism that allows me to recover quickly if my four disk RAID 0 drive fails, as it certainly will, sooner or later. But that is primarily an issue of convenience , as the operating system and applications could be restored after some effort, assuming the important stuff, my data, can be recovered.
The third is an archive mechanism, which can record a snapshot of what existed as of a particular point in time, in case I need to prove who knew what, when, or recover data from several years ago.
Obviously, the solution to most of these problems is a Drobo, but which one, and how?
I’m not particularly concerned about the performance issues. Time Machine runs once an hour, in the background, and I don’t really care how fast it does its job – it certainly will exceed my typing speed.
One option would be to carve out a volume on the DroboPro, and use it for Time Machine. that would give me the advantage of RAID 6, which I consider invaluable.
Another option would be upgrade the drives in one of my Drobos, and use that for Time Machine. ?that would be a relatively inexpensive solution.
Now, there was a lot of discussion on this issue on the old forum, but that data is lost. So now I need some advice.
Should I carve out a partition on the DroboPro for Time Machine, and in addition use another partition for the archive and other functions, taking advantage of the RAID 6 capability? Or should I use either Drobo or DroboPro for Time Machine, and another drive for everything else?
I could probably sell several of my four Drobos and buy a second DroboPro, which would provide much better reliability, but might diminish the overall redundancy, considering the possibility of equipment failure.
Decisions, decisions. Advice is welcome.
