I am in the process to install a backup solution for 15 remote site. I
would like to ask the group, what they are doing for thiers remotes sites
backup. Almost all my remotes sites have a 10MB link with us. We have to
install new server in each site. We scale a maximum of 300GB of data per
site with 5% of data movement per day. We estime a stadart backup solution
with a Networker licence/tape backup/cartrige at 10K$. So we have at 150K$
to spend.
Can we do better with that 150K$? We love to remove the backup from the
user hands and make them centraly. Saddly, we have to choose the solution
rapidly, so not much time to test.
From personal experience, a number of small remote sites takes a
disproportionate amount of time to manage compared to much larger
central sites, so if possible I would be looking at an alternative. If
you are considering standalone drives as opposed to libraries, you need
to plan your schedules carefully based on the capacity of a single tape,
and you also need very reliable local staff who will always be on hand
to change tapes as required.
You could possibly consider a solution where the remote data is
replicated to your central site and backed up from there. You would need
to invest in more disk storage on your central site. The disadvantage
may be the time taken for a large restore, although I'm sure a decent
replication package would help out with that. I don't have much
experience of replication software so I'm sorry I can't suggest any
specific details.
