Creates an on-demand backup of live content in a site's collections.
By default, all of the site's collections are included in the backup. For a partial backup, specify which collections to include in the backup.collections parameter.
The process of creating a backup takes time. You can check whether a backup has completed successfully with List Backups.
You can store up to 3 on-demand backups for each site. If 3 on-demand backups already exist, the oldest existing on-demand backup for the site is deleted when a new one is created. Automated backups are not affected.
