[BackupPC-users] Can $Conf{DumpPreUserCmd} and $Conf{DumpPostUserCmd} be

We are just beginning to use BackupPC running on a Debian Linux server to backup our Exchange Server 5.5 databases via rsyncd running on the Windows NT 4.0 server where Exchange is installed.

Currently, we have bat files scheduled to run on our Windows NT 4.0 Exchange Server to stop Exchange services before the BackupPC job runs and start Exchange services afterwards. But this means we're estimating the length of time needed for the backups and scheduling these jobs with a safe margin in either direction.

I am concerned that: 1) we are leaving our Exchange database down longer than necessary; and 2) if something goes wrong and the procedures that stop or start the Exchange database run while BackupPC has the Exchange files open for backup, we may corrupt our Exchange data (am I being paranoid here?).

It would be nice if the BackupPC job itself could issue the "net stop" and "net start" commands and I'm assuming I would use the $Conf{DumpPreUserCmd} and $Conf{DumpPostUserCmd} but I don't understand from the documentation how this would be done if you're issuing commands to a Windows server. Maybe this is not possible?

Can someone tell me if/how I could use $Conf{DumpPreUserCmd} and $Conf{DumpPostUserCmd} to remotely stop and start Exchange?

Does anyone know if there is any risk around attempting to stop or start the Exchange services while BackupPC has the files open for backup?

Thanks much.
