Jessie,
It is possible to issue the commands from Linux to stop / start Exchange
as you require if you use a third-party utility.
See http://eol.ovh.org/winexe/index.php for the details.
You may also be able to use the utility and back up Exchange without
stopping the Exchange server *at all* by using the "shadow copy" feature
of Windows. See http://www.goodjobsucking.com/?p=62 for an example of
such an implementation.
Note: the version of winexe at the link above requires a glibc version
of 2.9 or greater. An alternate version which supports a glibc version
of 2.3.4 or later can be found at
http://eol.ovh.org/winexe/winexe-static-081123-glibc-2.3.4.bz2 , but I
haven't tested it completely - your mileage may vary.
Regards,
Peter

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.
Jess
