Well Rob, we use one software called CA BrightStor High Availability Manager.
It´s mainly intended to do replication of a specific server onto another, and
it also has failover features, but it can be used for replication only. It does
realtime replication to another box, it´s a real lifesaver.
Brighstor ARCServe Backup also lets you backup stuff onto a file system device
that you can set on your home office, it´s a very powerful tool. It has a
module called Image Option that works sorta like Symantec´s Ghost, in which you
might be interested.

Hello everyone--
This is off topic, but I'm asking because I figure a lot of you are involved in
backing up servers. Hope you don't mind. (Considering all the "test" emails
that go over the list, people ought to be used to a little OT noise! ;-)
Anyhow, my boss is keen to ditch tape backups all together, and I agree with
him. We have multiple servers in remote locations that all get backed up to
tape (when the remote people remember to put them in). We have multiple local
servers that get backed up to tape, but due to the number of them and the
amount of data getting backed up, the backup process is getting progressively
more complicated. So I'm looking for a solution that would initially allow me
to backup the remote servers to some non-tape media, probably located here in
our home office. Over time, I would probably want to move the local servers to
the same, or at least a similar, backup scheme.
So far I have looked in depth at two solutions, neither of which is perfect for
us. One is Veritas Storage Replicator. Basically, it makes an exact copy of a
server (or whatever parts of that server you tell it to copy), onto another
hard drive somewhere else, and then keeps it up to date. This works well over
our wire to the remote offices. The problem with this approach is that you
can't go "back in time" with it. Suppose, for example, that a person deletes
half the content of a Word doc on Wednesday. Then on Friday she finds that the
deletion was a mistake. The replicated data will only have a copy of the
current file, which has been half deleted. The way around this, of course,
would be to backup the replica copy, either to tape or to another hard drive.
(This is what Veritas recommends.) But then I'm probably going back to tape
again, and the job just got more complicated. I'm trying to ditch tapes and
keep it as simple as possible. Oh, and keep the job as cheap as possible, too!
A second solution I've looked at is using a third party service. This solution
is pretty ideal except for a couple of things. First, I'd have to rely on
someone else to do an error-free job. Second, I'd have to pay on a monthly
basis by the GB stored. Even with the significant up front costs of the first
solution, it would pay for itself in a couple of years (or less) versus paying
by the month.
So, I'm interested in any non-tape solutions that anyone else is using. What
are the pluses and minuses? What's the software package? Etc. We are a mainly
MS shop, so would prefer a Windows-based solution. But we would be willing to
consider an open source solution.
Thanks for any input,
Rob
