Hi everyone. First post here. I had a “wake-up call” recently (sorry of the story is a bit long): My main data drive failed and even if I had a time machine backup, the downtime was not ideal (checking if the original disk could mount and/or let me salvage anything, getting the disk replaced, restoring the backup of a 3tb drive). Close to 2 full days + a good chunk of stress I would like to not deal with.
It may be fine for a computer I use only for personal use, but I started my own business 2 years ago, and I would like to minimize downtime as much as possible. I basically want to get as close as I can to getting a flat but being able to get going (does that mean changing a flat in no time, having a backup car or hitching a taxi ride I do not know yet)
I do have my main computer, plus a mac mini (2014) and a macbook air (2014). So if my main computer fails, assuming my data is not enclosed, I think I can keep going.
99% of my work happens on my main computer, so I don’t think I need a NAS. With this in mind, I am starting to consider a DAS device for something that would let me do RAID 6. Having drive redundancy is a concept I like. Did I say that my time machine backup drive also failed just 2 weeks after restoring my backup? That too was part of the wake-up call.
RAID enclosures are nice, but in terms of continuity, they move the problem from the single disk to the hardware/software used to run it. Is it overkill to want to get 2 units simply to be able to swap the disk from one unit to the other while seeking service/replacement for the failing unit?
Here are the players I hear about:
- Drobo (5D3)
- G-Tech shuttle / shuttle xl
- Promise Pegasus
- Something using SoftRaid
What I like about Drobo is that it is not as pricey as G-Tech / Promise (specially if I end up getting 2 units). But it is proprietary. I like the flexibility, but don’t like the lock-in so much. I also don’t like it requires software because (like with SoftRaid) OS compatibility can be problematic, so you have to be careful about updating your OS.
G-Tech looks amazing, but I cannot get two of that ($$$), so maybe I could get by with just a larger disk I replicate onto (with ChronoSync, CarbonCopyCloner, or similar software).
Maybe I’m going over the top, I should just replicate daily on a same size disk with CCC and that would be just fine.
Please tell me what you think, things to watch for, etc.
