At Hostinger, we do provide daily backups with the majority of our hosting plans - the only plans that have weekly backups instead are:
Shared Single
Shared Premium
Single WordPress
WordPress Starter
VPS plans
If you want to have daily backups on one of the mentioned plans, you can easily order them via hPanel: just open Hosting → Manage:

In the Files section, click on the Backups button:

And click on the Add Daily Backups:

Daily Backups for VPS can be activated via the Servers → server in question → Snapshots & Backups page.
NOTES:
If you don't have daily backups, your backups will be generated weekly
On all Shared and WordPress plans, you will get Daily Backups if you upgrade your hosting plan (to Shared Business/Business WordPress or above)
