It's best to schedule things to *not* run at the times you *don't* want them
to go off. Gives the software more flexibility to get the job done when it
can. (Sometimes scheduled backups fail; giving the software some flexibility
lets it try again).

That said, if you need to force a backup to go off at a particular time;
best way to do it is with a cron job that sends a message to the software
telling it to initiate a backup.

# do incremental backups of this machine most every workday at noon
00 12 * * 1,2,3,4 backuppc /usr/share/backuppc/bin/BackupPC_serverMesg backup host.domain.tld host.domain.tld backuppc 0

The '0' in the above example means do an incremental backup; a '1' would
mean to do a full backup. I don't remember what the syntax means anymore;
this is just a sanitized example that I have of backing up someone's laptop
over their lunch break.
