I see there is an option for the Sage 50 automated backup, but not 300 CRE.

What are my options for an automated backup for the Sage 300 CRE data? Or maybe should I ask the more broad question of how does everybody handle backups. I am looking into using a Barracuda Backup box to backup my server that Sage is installed on. My question would be how does it handle backing up the database? I am under the assumption that you cannot just "drag and drop" to copy the company folder as some data may end up missing.

I was also told to run Sage on a virtual machine and take snapshots as well as running the Sage backup from within the software. Problem is that I would rather not have to run it every night after everybody is out of the system. Is this the job of a script or a 3rd party software that can back up a PSQL database?
