How do we take a backup before a major project cutover and restore it from a backup?

Summary:

We have a major project cutover going live.
Before the major cutover , we need to take a backup.
there are no code changes in GTM cloud.
Most of the data will be fed to GTM Cloud from upstream systems.
if upstream systems decide to not go live because of any catastrophic issues, we should be in a position to restore GTM cloud from the backup before the cutover.
