Hey,
Yes, that is recommended
Virtuozzo backup functionality is not intended for actual backup usage, as the files are stored on the same Hardware node on which your VPS will be located. This is only intended for when you for instance are about to install a new application on your VPS, and you want to be able to easily roll back to the point before you started (in case something went wrong).
For actual backup usage, it is best to store the backups remotely. As you are going for cPanel Control Panel we can configure daily, weekly and monthly backups for a complete account including mysql databases.
