SharePoint plugin: Performance and throttling configuration

Last published : Apr 02, 2026
BackupExec Microsoft 365 SharePoint Online plugin is designed to protect data.
A SharePoint site can contain:
  • Small or large files and folders
  • Different types of files (simple text files, videos, and images)
  • Lists with different template types (Document libraries, Event lists, System lists)
  • Number of subsites
The plugin ensures that all the data is backed up and restored with minimum throttling and with optimum performance.
Performance of backup and restore for SharePoint Online depends on the network and the amount of throttling observed from Microsoft 365. Microsoft 365 SharePoint Online throttle requests to maintain optimum performance. Backup Exec also observes the same throttling when sending requests to Microsoft 365 SharePoint Online.
All the best practices mentioned by Microsoft are followed by the plugin. For more information, refer to the following link:
The plugin has the mechanism to reduce the throttling. It helps in scenarios where there are many SharePoint/User/Group sites, which must be backed up and total data size is large (hundreds of GBs to TBs). Although the default tuning works, some tuning may be required for specific scenarios.
