@Uziel Silva Thanks for reaching out to Microsoft Q&A, apologize for any inconvenience caused on this.
Does your custom backup include DB config as well?
As mentioned in the documentation here, using custom backup, you can capture backup max of 10GB size in which 4GB is related to database which is connected to the webapp.
If your app service is not connected/configured to database, then the entire 10GB backup size will be used for the application only.
I have checked with internal team, and they have confirmed that these are hard limits there is no chance of increase the limit as well.
Alternatively, to fulfil your requirement and your app service is not connected to any DB then you can refer to the below solutions.
- You need to either reduce the back size of your application.
- Use Automatic Backup which has max size of 30GB, also all the backup files that were taken by automatic backup will be stored in the backend and you cannot find under your subscription.
Hope this helps, let me know if you have any further questions on this.
