Pre/post commands for Linux (RALUS client) on Backup Exec 2012

Refer to this post https://www-secure.symantec.com/connect/forums/linux-remote-client-ralus-2010-prepost-commands-remote-client (is says that:

The pre/post commands are designed for windows systems only.

I would recommend that you look at using the CRON utility to schedule commands in Linux/Unix.)

which belong to BE'2010 is something changed in Backup Exec 2012?

P.S. My configuration is SymBE'2012 with latest updates and RHEL 6.0-6.3.
