I agree with Doug on NFS mounting the filesystem, then backing up to it. I
would also reiterate however that all pipes (network) are different. I have
done testing on our systems over gigabit ethernet and 100mb fiber. I had
problems not during the backup but during the restore (remember, both
utilities have to work and should be tested!) Use the nfsstat command - or
whatever the equivilant is in linux (I'm on AIX) to check for errors/bad
calls - during the utility execution.
If that doesnt work, do it to a local filesystem but I'd use rcp versus
ftp. Then you can do it all via crontab.

Subject: Re: DB2EUG: backup of DB2 7.1 over network..
I've had similar problems with the backup command. There must be some
implementation details that assume access to the filesystem. One way
I've gotten around this is by nfs mounting the backup machine, then
pointing the backup to the mounted filesystem. It's a little slow,
but it works just fine. And although nfs is not very secure, it's
better than rsh.
Another option is to write a script to backup locally, then ftp the
backup files to the other machine.
