Backing up and restoring data consumes server resources, therefore, limiting its performance when the operation is running. To ensure that you increase the performance of the servers and the restore task or backup and reduce resource usage, follow these best practices.
Avoid processing conflicts
One of the ways that you can ensure the performance of the server is not affected when backing up SharePoint is to do it when no other users need access to the system. The best time to do this is at night if the system experiences high user traffic during the day and vice versa.
Use compression during backup
Decreasing the size of the data to back up can help free-up server resources for other users to use without compromising the performance of the system. However, remember that CPU usage increases during backup compression and this can affect SQL Server concurrent operations.
