Thank you JLHC & regarding Magento, one of the reasons I need to upgrade the server is that the backend admin backup option times out as the server is too slow to handle the backup.

Is there an alternative to fully backing up Magento before the server upgrade?

I do have a full backup of the Virtuozzo Automation Container that holds Magento within it but I'm being extra cautious as I currently do not have direct Magento backups due to the server processing power.
