We have a large number of Synergy Databases on a Windows 2000 server, which is fine and does not cause any problems under normal conditions. We have a backup script that runs each night backing up the databases between the hours of 22:00 and 01:00 the following morning. We have had a couple of instances in the last 2 weeks where users have been dialled into the system over the VPN and caused contention with the backup routine which has then stopped and aborted with only "n" of the databases backed up. Does anyone have a fool proof method of doing backups, so that if a problem occurs, then some intelligent process can pick up and carry on where it's predecessor failed.

I'm not familiar with Windows, but I guess you can handle it like we use to do it at Unix.
At the beginning of the nightly batch window, we start a job scanning for existing databases and comparing them with a list of databases excluded from backup. For each database not in this list, a job is submitted for parallel execution. After submitting the jobs, this job will monitor its child processes. When a child finished, it take a look into its output to find out whether it succeeded or failed. In case of failure, you can just try again or act depending on the reason code. I guess, this part will be handled specific by each admin.

cu, Lutz
