running a command/script BEFORE a backup starts

[David Heafey]

Folks,

I have a source code control system (Perforce) running on a Solaris Amanda
Client (2.4.1p1).  Perforce has the ability to "checkpoint" its metadata in
journal files, essentially taking a human-readable snapshot of the metadata
at that particular.  I'd like to do this checkpoint and then backup the
checkpoint
with as short an interval as possible between the 2.

Is there a way to run a "pre-backup" script or command prior to Amanda
starting the backup?

Thanks,

Dave
