A backup in general is something that you have and you can use in case your normal operation or plan fails. You do not do or perform such a thing.
In an IT environment, when you create your system image:
you create a backup
you make a backup
you take a backup
you perform a backup
The "take" on I hear especially in database-environments; the "perform" seems to confuse very few people.
When you use the backup to restore the crashed system:
you restore from a backup
Outside IT environments, you can also have backups.
A common occurrence is a backup plan, which you can make and then have. If the original plan fails, you can put your backup plan into action, or execute your backup plan.
Note that here you do something with the plan, not with the backup!
A backup can also be a person who can take care of your tasks and / or responsibilities when you are not able to do so. I would not advise to execute that person.
