Open file support

Edit online

If open file support has been configured, the backup-archive client performs a snapshot backup or archive of files that are locked (or "in use") by other applications.

The snapshot allows the archive to be taken from a point-in-time copy that matches the file system at the time the snapshot is taken. Subsequent changes to the file system are not included in the archive. You can set the snapshotproviderfs parameter of the include.fs option to none to specify which drives do not use open file support.

Use VSS as the snapshot provider for open file support.

Note:
  1. You can use the include.fs option to set snapshot options on a per file system basis.
  2. Open file support is only available for local fixed volumes (mounted to either drive letters or volume mount points) that are formatted with NTFS or ReFS file systems. This support includes SAN-attached volumes that meet these requirements.
  3. To enable open file support in a cluster environment, all systems in the cluster should have VSS configured.
