This chapter covers the following topics:
On-Demand Files in OneDrive
OneDrive On-Demand files help you to access all your files in OneDrive without downloading them and using storage space on your Windows device.
OneDrive (formerly known as SkyDrive) is an online Microsoft cloud service. OneDrive is integrated with Windows 10 as a default location for saving user files. This allows the saving of photos and any other files across multiple devices.
A user can also save their files in OneDrive and have them automatically synchronized on other devices. This means someone can access and work on the same document in multiple locations.
Once Files On-Demand is enabled, you see all your files in a file manager. New files created online or on another device appear as available online-only files, which do not take up space on your device. Once your PC is connected to the Internet, you can use the files like every other file on your device.
On-Demand File Backup
Starting from version 6.3, Backup for Windows enables On-Demand file backups.
How It Works
If On-Demand files backup is disabled, as a backup plan runs, On-Demand files that available online only (Unpinned) will be downloaded from your OneDrive storage, then uploaded to backup storage specified in the backup plan. After these files are backed up, they will be marked with an Unpinned attribute which means that these files are available online. Locally stored files (with Pinned attribute) will be backed up in any case.
While downloading On-Demand files from the OneDrive cloud, a maximum downloading period is set for each file to be downloaded. These periods are calculated separately for each file. A period is calculated as a ratio of file size to 10 Mbps speed. For example, a downloading period for a file 200 Mb is approximately 2 minutes
If a file is not downloaded within the calculated period, an error occurs (Code: 1614. Cannot back up n OneDrive On-Demand files. Download timeout)
If the VSS snapshot mechanism is used (can be specified on, On-Demand file are processed as regular, so that is, the file is taken from the OneDrive folder and is uploaded to backup storage. On-Demand files are not taken from a VSS snapshot
