I don't think so: the same technique
is used by the Perl code to create the archiveReq file. The reason
that's done is to ensure a unique name, not to allow it to know what the
PID is.
If you check the Server Status page
while an archive is running, you'll see that BackupPC knows the PID of
the process properly.
Here's a question: have you tried
using the standard GUI to start and stop an archive? From my recollection,
BackupPC won't kill the tar immediately even when it's started from its
own GUI. I usually have to go in and kill the process manually no
matter how the archive job is started. But my recollection may be
incorrect.
On a different note, I would be interested
to see your PHP code.
