Updated

Verify that the access nodes for OneDrive for Business meet the guidelines. An access node is a virtual machine, a cloud instance, or a physical server that runs backups and other operations.

Note: For high availability (which is recommended for the first full backup), use 2 or more access nodes and extra Azure apps.

Assumptions

The guidelines are based on the following assumption:

  • The average user account size is 10 GB.

Job Results Folder Size

With an average user account size of 10 GB, and a backup job running in 10 streams, the job results folder can grow to a maximum of 500 GB.

With n number of parallel backup jobs running, the job results folder can grow to a size of n*500 GB.
