Trying to polish the final fine details of software RAID mission critical home-server solution. I am curious about the server performance in RAID-1 (mirroring) degraded mode (where one of the hard disks failed). Will it make it till the next day (or more) if I am in the middle of finishing some critical project or I am supposed to replace the second disk as soon as possible?
The rationale of the system I've came up with is software RAID (with mirroring) and daily backup. My thought was that if RAID fails then I still can finish the workday (have a last day backup anyway) AND then replace the damaged hard disk. How real/feasible is the scenario?
To clarify, I'm considering to utilize Ubuntu-based software RAID implementation.
PS: if the scenario is totally not feasible, then I can consider replacing RAID-1 by RAID-5. Will it work better?
