I had previously posted that I had mounted an external hard drive (Seagate external 1.5 TB) and mapped my /var and /usr to the drive. I have two identical drives and had intended to create a back-up strategy. I had not implemented one (6 months down the road) and, of course, the hard drive that I have the data mapped to has a malfunction rendering my plug inoperable for the moment.
I'm looking into what might be done to recover the data and it appears to be a minimum $500 charge.
I posed the issue of drive manufacturers providing data recovery on reddit
when their drive fails and the unified response was pretty much: I'm a dumbass
and should have had the data backed up, presumably by RAID. (I've been researching the issue and it looks like an external RAID controller exposed as a USB drive would be the safest solution; you're then placing your data at risk of the design/implementation of the RAID controller, some of the cheapest
ones seem to have postings on forums of completely losing their data.)
Given the SheevaPlug's design of not having internal drives and a linux community's opinion that back-up is a requirement, I wonder what people developing on the SheevaPlug do for their back-ups. Seems that if you are using a hard drive, you probably should use two (as I did, but never configured as I planned) to protect yourself when one goes bad. In another posting to this forum, the opinion was a software RAID is unacceptable, and I"ll agree with that opinion.
So what are people doing who attach hard drives to the plug? Or is the safer course using multiple stick USBs and not having a lot of data?
I guess what I'm thinking is that if you are using an external hard drive, it must be in conjunction with a backup system.
