I have a home network consisting of two computers connected to a
small router via 10/100 Mbps ethernet. I have 4 IDE hard disks, each
200GB or less. The operating systems are Windows XP SP1 and SP2,
Windows 98, Linux Red Hat 9, and Linux Fedora Core 3.

Now for the hard bit - what's the easiest way to keep all of these
IDE hard drives backed up, e.g. if one of my hard drives gets errors and
fails, I'd preferably like to just replace it with a backed-up
hard drive and have it work.

I believe I would want one or more backup 'devices' to be connected
to my router, i.e. I don't think I want to keep opening up my
computers and keep putting in individual backup hard drives every
time I want to do a backup. The question is, what should those
'devices' be?

I'm a complete novice in backing up, so don't assume that I know
anything. By all means include any brand names in your answer.

Corporations don't have a lot of time to waste, so how do they do it?
I don't necessarily mind spending some money if it will give me
reliability and convenience.

Would hardware RAID 1 or RAID 5 work?
- Backing up: can the backed-up drive(s) sit on the network
outside my computer? The original hard drive is obviously
inside my computer.
- Restoring: if one of the hard drives
in my computers fails, can I replace it with a backed-up hard drive
and have it work? Will both Linux and Windows still work?

I understand that RAID is rather expensive but it may be worth it
depending on the price.

If that's possible, then I think this still leaves to have to deal with
one more backup methodology - if some files get deleted accidently, then
in the back-ups they will be deleted as well.

So I probably need something which also allows me to do a few
historical backups. I suppose I need something which can image my hard
drives, and (to save on cost) with the option to allow incremental
backups on subsequent backups?

I tried using Norton Ghost 9 in XP SP1 (whilst XP was running - apparently
it's supposed to support this). I did it the hard way by opening
up my computer and connecting the backup drive to it. (As I wrote above,
I'd prefer if I could have the backup drive on the network all the time,
if possible).

But it didn't work for me. Some logical drive letters seemed to back up
fine, others didn't. So I have a portion of the files backed up,
but the hard drive won't boot - Linux Red Hat 9 complains that
/boot has a 1-byte size difference compared to what is in the
Master Boot Record. Whereas Windows XP boots up to the XP logo,
but that's all it shows - it doesn't give me the normal password prompt.
On the web this Windows XP problem is mentioned by many people, but
I could never find a solution.

On the web I've researched a few backup devices. Something like
Netgear Storage Central (SC101) sounds good in that it allows you
to put in your own hard drives of your choice.

Buffalo TeraStation comes with an attractive 1TB of storage via
4x250GB hard drives, but I don't believe the hard drives can be taken out?

In any case if my understanding is correct, both of these devices
basically allow you to backup files. By themselves, I think they don't
come with anything to allow me to take full images of my hard disks - is
that correct?

Cheap way to do it--back each machine up to the other.

You don't have to open your machines--put your drives in removable caddies.

Tape. Big honking arrays of high end tape drives.

I don't necessarily mind spending some money if it will give me
reliability and convenience.

This isn't backup, this is reliability.

- Backing up: can the backed-up drive(s) sit on the network
outside my computer? The original hard drive is obviously
inside my computer.

While this can be arranged it takes some doing and it's not going to be
cheap or simple. You're basically looking at something like iSCSI.

- Restoring: if one of the hard drives
in my computers fails, can I replace it with a backed-up hard drive
and have it work?

In general, if one drive is local and the other network attached, no.

Will both Linux and Windows still work?

That depends--if the RAID is working at the hardware level, yes, if it's
working at the software level, probably not. One or the other, yes, both
on the same drive, not likely.

I understand that RAID is rather expensive but it may be worth it
depending on the price.

Not all that expensive. But it's still not backup.

200GB or less. The operating systems are Windows XP SP1 and SP2,
Windows 98, Linux Red Hat 9, and Linux Fedora Core 3.

So that are multiple OS per computer and various file systems too.

Now for the hard bit - what's the easiest way to keep all of these
IDE hard drives backed up, e.g. if one of my hard drives gets errors and
fails, I'd preferably like to just replace it with a backed-up

There is nothing like that.
Usually you have to replace failed disk with a new one, THEN restore data on
it.

I believe I would want one or more backup 'devices' to be connected
to my router, i.e. I don't think I want to keep opening up my
computers and keep putting in individual backup hard drives every
time I want to do a backup. The question is, what should those
'devices' be?

Any form of disk storage. I do it through a Windows server with additional
HDs.

I'm a complete novice in backing up, so don't assume that I know
anything. By all means include any brand names in your answer.

Corporations don't have a lot of time to waste, so how do they do it?
I don't necessarily mind spending some money if it will give me
reliability and convenience.

They usually do not backup user workstations.
For other data they have servers.

Would hardware RAID 1 or RAID 5 work?
- Backing up: can the backed-up drive(s) sit on the network
outside my computer? The original hard drive is obviously
inside my computer.

RAID over network? Not in consumer market.

- Restoring: if one of the hard drives
in my computers fails, can I replace it with a backed-up hard drive
and have it work? Will both Linux and Windows still work?

There is nothing like that yet.

I understand that RAID is rather expensive but it may be worth it
depending on the price.

RAID over network? You budget is too small.

If that's possible, then I think this still leaves to have to deal with
one more backup methodology - if some files get deleted accidently, then
in the back-ups they will be deleted as well.

You can generate multiple images on schedule basis.

So I probably need something which also allows me to do a few
historical backups. I suppose I need something which can image my hard
drives, and (to save on cost) with the option to allow incremental
backups on subsequent backups?

Incremental? Not possible/reliable yet with multiple OSes/FS on one disk
More difficult to restore.

I tried using Norton Ghost 9 in XP SP1 (whilst XP was running - apparently
it's supposed to support this). I did it the hard way by opening
up my computer and connecting the backup drive to it. (As I wrote above,
I'd prefer if I could have the backup drive on the network all the

Could use USB external drive. Saves from opening computer case.

But it didn't work for me. Some logical drive letters seemed to back up
fine, others didn't. So I have a portion of the files backed up,
but the hard drive won't boot - Linux Red Hat 9 complains that

Ghost 9 is a crap anyways.

O course they can be taken out. But why?

That function is in your imaging software which runs on a CLIENT system, not
storage device.
I boot my client systems with a custom CD, which does a full client PC
disk(s) image(s) to a server storage. Unattended image completion and
shutdown. Another version of it can restart client system after imaging.

The whole thing would be easier if you ran a file server (which could be a
very humble computer with a couple of large HDDs in it). You could store
ALL your files on the server and back it up with tapes or an external hdd.

Custom CD is based on WinPE. It automakes connection to a server share.
Enumerates local hard drives and launches ghost32 unattended image dump for
each of them. Then, shuts down PC. This version works for ghost supported
filesystems only.

Correct. If you restore the image of the SystemRoot disk of Windows,
you
must
either:

Are you talking about restoring a disk image or a partition image?

Partition. With disk image, all is fine.

Exactly. It wasn't clear when you have used "image of the SystemRoot disk of
Windows" phrase.

Exactly. It wasn't clear when you have used "image of the SystemRoot disk of

Yes, my usage of the word "disk" was bad here. Should be - "partition" or
"volume". "Disk" is usually the physical disk.

SystemRoot is the startup directory of Windows - C:\WINNT, C:\WINDOWS or such.

I use True Image 8 (TI9 demo is available at www.acronis.com, but I
haven't tried it yet) to back up to external HDs. Works great, fast
recovery. You'd have to run this under Windows to get automatic
backups.

In your situation, I'd consider backing up each to a local external
drive (one external on each computer), then copy each backup set to
the other computer's external for a little bit of redundancy.

Correct. If you restore the image of the SystemRoot disk of Windows, you must
either:

a) also restore the MBR, so that the new disk will have the same MBR Signature
and the SystemRoot partition will have the same offset

or

b) mount the SYSTEM registry of _this restored Windows image_ on some another
computer and patch the MountedDevices value manually, so it will be the same
drive letter as the original disk was.

Windows assigns the drive letters on "mountdev ID" basis, and the "mountdev ID"
of the usual disk partition on an MBR disk is - 12bytes, 4byte MBR signature of
the disk, then 8byte partition offset (in bytes IIRC).

The HKLM\SYSTEM\MountedDevices registry contains the table of the drive letters
in the form of:

\DosDevices\C: REG_BINARY: mountdev ID
\DosDevices\D: REG_BINARY: mountdev ID
\DosDevices\E: REG_BINARY: mountdev ID

and so on.

If you will not patch this in the new restored Windows disk - then it will boot
and will assign itself as, for instance, T:, while all pathnames of services,
Windows user mode components and COM objects (including the shell components) -
are starting from C:\. This is a major failure, the system seems to be up, but
you cannot log on.

The whole thing would be easier if you ran a file server (which could be a
very humble computer with a couple of large HDDs in it). You could store
ALL your files on the server and back it up with tapes or an external hdd.

I had an old PC running as a file server/backup device. However one mistake
I made. The drives on the backup machine were two SCSI drives and a adaptec
controller (which I obtained for free). Worked great for 2 years until the
controller, or both drives packed up.

I could not justify a new SCSI controller, but luckily both my PC's that I
backed up data FROM are still ok.

I've since changed to a Netgear SC101 with two mirrored 80gb drives as my
backup drives.

As an extra precaution I also copy mydocs (plus any important stuff) between
both PC's using Save-N-Sync
