Description

By default only one application gets created to backup the Sharepoint Online data within the Tenant but a user can test by configuring additional applications as well. This may improve backup performance by reducing the throttling effect or atleast reduce any throtling related errors during backup.

These applications help tackle throttling issues which can occur when communicating with the Microsoft API's. The applications are given specific permissions with respect to the workload where throttling is encountered.

Since applications within a tenant have limits on their usage, using multiple applications would help to load balance the communication with Microsoft servers.

Note : Backup Exec follows the best practices recommended by Microsoft to handle throttling. Refer this link for more details https://learn.microsoft.com/en-us/sharepoint/dev/general-development/how-to-avoid-getting-throttled-or-blocked-in-sharepoint-online
