No. You don't.

Then your host is broken. No amount of BackupPC-manipulation
is going to change that.

No. You don't. Repeating it doesn't make
it true.

That is *so* far from your "only other option"
it's not even funny.
I am assuming that the host is capable of the following:
Consistently able to successfully read the data on
its hard drives.
Consistently able to talk across the network.
Talk to other pieces of hardware (USB drive? eSATA?
NFS-mounted partition? SMB-mounted partition?)
If it is, there are dozens of ways of getting the
data from point A to point B.
Nobody said you would do it *directly*; you
keep telling us that it's broken, and I'll take you at your word on that.
So widen your vision a bit...

You are limited only because you are allowing yourself
to be limited. Your broken CentOS system is the ONLY COMPUTER YOU
HAVE ACCESS TO that can talk iSCSI? If so, change that. If
not, you can think of NO WAY TO TALK TO THAT OTHER COMPUTER from your broken
CentOS system? If so, figure out a way that you can!
You keep saying "I can't talk iSCSI from my CentOS
system. I must talk iSCSI from my CentOS system to get it on the
SAN. HELP!" Do you see the problem with this?
Until you change one of those underlying assumptions,
there will be no answer. Personally, I think the second assumption
(I must talk iSCSI from my CentOS system) is the easier one to change.
Change it.
