Hi,

I need to urgently know about differential backups and incremental backups.

We are running SBS2000 and a member file server on our domain, which is
clearly taking far too long to backup due to the capacity of it.

We are running CA's ArcServe V9 with b/up agent for open files and client
agents.

Thanks in advance.

Incremental and differential both start with a full backup. After that,
incremental backups back up only what has changed since the last incremental
backup. So, if you do a full backup on Sunday, then an incremental backup
every day thereafter, let's say your server crashes on Thursday. You
restore Sunday (full), Monday, Tuesday, and Wednesday.

For differential backups, everything since the last FULL backup is backed up
every day. So in the same scenario, you'd restore Sunday (full) and
Wednesday.

If this is confusing, please see the incremental vs. differential help topic
in Arcserve Help.

Are you backing up client machines over the network? If so, that's likely
why your backups are taking too long. If you can move data to the server,
that would help. Also, if you can make sure the users put all important
data in My Docs and only back that up, that may speed up the process.

I'm not sure whether or not you'd get better results with a newer version of
Arcserve. Also, you might benefit from faster backup hardware, particularly
if you're using Travan or DDS.

Our problem is a client machine using dBase v5.7 and dBase for DOS. When the
backups kick in, the user has two machines which contains the data and his
program. It causes his program to crash.

He has around 200GB of data on his machine, but only 20GB everyday is
changed. So 80% of it still stays the same. Differential came to mind in
this scenario.

I did explain to him that the ArcServe BAOF and agents do not cater for
dBase (they do make a SQL agent) but he won't listen.

AGain, this only occurs when his dBase tables are open and ArcServe cannot
back them up, as it comes up with the reason : "Already open...used by
another process".

THis is not possible is it?

If you can write two batch files, one to stop his services and another to
restart them, you can then create a backup job for just that data. Go to
the Options, Pre/post tab. Set up the backup job to run the shutdown batch
file first, then the restart batch file after the backup completes. I
recommend creating a separate job for just this data, because the pre- batch
file runs at the beginning and post- runs at the end, so the programs will
be stopped for the whole time it takes the job to run.

I've done this successfully several times, so I know it works as you'd
expect, but you'll want to test it and closely monitor it for a few days
until you're sure it's working.

Good luck!
