#CO-Throttling

Issue:

Some items encountered errors during backup with the following error code:

Details:

This is the error code for 429 throttling issues.

Solution:

Due to the throttling control by Microsoft during weekday daytime hours, we recommend that you schedule backups outside business hours and consider reducing the frequency of backups as necessary during the workweek.

We also recommend you configure app profiles for your tenant with different permission types, such as SharePoint, Exchange, and All permissions. Therefore, Cloud Backup for Microsoft 365 backup services using app profile authentication will have choices for the data protection of different service types.

If the error persists, contact AvePoint support for assistance.
