A snapshot protects data by recording the state of a thick volume, thin volume, or LUN at a specific point in time. With snapshots, you can perform the following:

  • Restore a volume or LUN to a previous state.

  • Access and restore previous versions of files and folders.

  • Create an identical copy of a volume or LUN.

  • To use snapshots, your NAS model must support snapshots and have at least 1 GB of memory. For a list of compatible NAS models, see www.qnap.com/solution/snapshots.

  • Encrypted shared folders do not support snapshots. Although you can take a snapshot of a volume containing encrypted shared folders and restore the volume with the encrypted shared folders intact, you cannot individually restore an encrypted shared folder from a snapshot. Encrypted shared folders in a snapshot also do not appear in the snapshot directory (@Recently-Snapshot).
