On-line storage backup options

Rich,

    Most NAS are using some form of OS or stripped down embedded OS like
Linux. If you're using this as your primary repository I suggest the
following:

2 small drives 4gb-9g (use for OS partition) Mirror these.
Once your system is built out, I would recommend something like Ghost or
Partition Manager and make an Image of your OS drive, then burn it to a CD,
this way if your OS were to fail completely and you lost your mirror or
mirror were to be corrupted you could build out a new OS partition in a
matter of minutes by booting from a DOS disk and imaging the new drive.

1 small drive again like a 4gb for your SWAP (you could mirror, but I think
on a small personal server, that is overkill for /swap)

If you require any app above system apps, then I would place apps on another
set of drives, and mirror them.

Now for the important stuff, your data, definitely consider Raid 0+1, get a
pair of raid controllers (IDE or SCSI, your choice) I prefer SCSI myself,
setup your Raid, Raid 5 is best, it chews up the most disk space for the CRC
data of the other disks for rebuilds, but its the most reliable.... Now
on a seperate identical controller and drives, mirror the primary raid
partition.

Finally, a smart UPS system so your NAS server can orderly shutdown in the
event of a power failure and your reduce data corruption.

This is a good setup for low failure and fastest recovery.


You can find some nice Dec (aka Compaq, aka HP) Storageworks RA8000's fairly
cheap these days, I've worked with them and 12000's and they are wonderful
systems, you can pick up a cheap fibre channel card and hook up a server
right to if and serve the storageworks data from that server (like a very
simple linux RH box or the like)
