How to manage huge backups before upgrade? [closed]

asked 2016-04-25 09:26:31 -0600

I want to know the recommended method to manage backups before upgrade to next release. Is it required to allocate additional storage space for backups prior to upgrade? Or just the regular backups are enough? Which doc to be referred for backup and backup restore?
