Variable backup size

Hello guys,
we are doing gitlab backup every night and we found out that backup files size varies.
Does anybody know why ?

It think the most common reason (and certain the main reason in our case) is build artifacts, if some developer makes a lot of builds of one project that generates huge artifacts, that will (typically) make the backups bigger (until the artifacts expire).

But there are probably other things in a backup that can vary in size, the registry comes to mind.

The only way you can know for sure is to check a couple of your backups. And if you find the variations comes from something you don’t want backed up, you can skip any part, see

(And our backups vary in size between 150GiB and 300GiB)


Thanks. You are correct.
After i modified cron, the backups have about 800MB each time.

Thank you.
