Define when to rotate your backups
Backup retention is the number of backups you want to keep available.
This value will be a number, ranging from 0 (unlimited retention, meaning we never delete your backup files) to whatever retention number you might need.
How does backup retention work?
Every time a backup runs, we check the number of backups you already have stored and if this number is higher than the retention value we delete the oldest backup files still stored.
When should I use backup retention?
A good practice is to always define a retention value, in order to avoid using too much storage.
The value will mainly depend on the context of the project you're backing up. When you created your backup, ask yourself the question "Till how long back in time do I need to be able to go if something goes wrong with my site/database"?
