Instead of doing all those things, I have a suggestion to make:
Something that is like RAID 4 without striping.
There are already 3 programs doing that, Unraid, Flexraid and disparity,

Disk A B C D E P

Block 4 4
This is exactly what I want for a particular application I was thinking
of putting together. I want to offer my customers nightly backups over
the 'net. That's easy enough, and well off the scope of this list. I was
going to save the data onto a big RAID of big discs, but I was wondering
what to do when the customer needs the data, because downloading the
data would take way too long, and I'm not taking my server offline to
take to their site. So I thought, hmm, run a disc for each customer,
plus a parity drive in case anything goes phut. Then when the customer
needs their data, I can yank their drive and go to their premises with
their data in hand. Of course, another option would be to copy the data
onto a spare drive, but even that takes a while if they're in a hurry.
Might have known somebody would already have done it.
Cheers,
John.
