Per the README located in the extraction directory /root/backuppc/BackupPC-2.1.2/init.d, I did the following:
RedHat Linux:
============
When configure.pl is run, the script linux-backuppc is created. It
should be copied to /etc/init.d/backuppc:
cp linux-backuppc /etc/init.d/backuppc
After copying it, you can test it by running these commands as root:
/etc/init.d/backuppc start
/etc/init.d/backuppc status
/etc/init.d/backuppc stop
You should then run the following commands as root:
chkconfig –add backuppc
chkconfig –level 345 backuppc on
chkconfig –list backuppc
This will auto-start backuppc at run levels 3, 4 and 5.
