Outlines how to use previous versions in Windows with Qumulo Core

REQUIREMENTS

  • Admin privileges required
  • Cluster running Qumulo Core 2.11.2 and above

IMPORTANT! SMB2 specification treats previous versions as snapshots on the volume and Qumulo supports snapshots within a single volume (per-directory snapshots). As a result, if you mount an SMB2 share above a snapshot in the directory tree, that snapshot will not be visible because it does not apply to the whole “volume” that is presented to Windows. To work around this limitation, you can mount a share deeper in the directory tree so that the snapshot applies to the whole volume.

DETAILS

With the release of Qumulo Core 2.11.2, we now officially support Windows previous versions. Previous versions are copies of files and folders created by Windows that can be used as a restore point in case a file or folder is accidentally modified, deleted, or damaged. Depending on the type of file or folder, you can open, save to a different location, or restore a previous version. 

Select a timestamp for old data

  • Right click on a share, select properties and click previous versions. Qumulo presents a list of all snapshots that cover this share at 1-second granularity. Double-click a specific timestamp to view the data as it existed in that snapshot.
