File-level backup is available for physical machines and virtual machines backed up by an agent installed in the guest system. Files and folders located on disks connected via the iSCSI protocol to a physical machine can also be backed up though there are limitations if you use Agent for VMware or Agent for Hyper-V for backing up data on the iSCSI-connected disks.
A file-level backup is not sufficient for recovery of the operating system. Choose file backup if you plan to protect only certain data (the current project, for example). This will reduce the backup size, thus saving storage space.
There are two ways of selecting files: directly on each machine or by using policy rules. Either method allows you to further refine the selection by setting the file filters.
Direct selection
The share must be accessible from the selected machine.
Backing up a folder with anonymous access is not supported.
Using policy rules
The policy rules will be applied to all of the machines included in the protection plan. If no data meeting at least one of the rules is found on a machine when the backup starts, the backup will fail on that machine.
Selection rules for Windows
You can use other environment variables or a combination of environment variables and text. For example, to select the Java folder in the Program Files folder, type: %PROGRAMFILES%\Java.
