Snapshots Logo
Snapshots
Protect and restore your data. Easy, and fast!

Taking a snapshot is like taking a photo - within seconds the complete status of your NAS system and data is recorded. If an unexpected situation arises on your system, you can revert to the state recorded by a snapshot. With greater space-efficiency and flexibility compared to traditional backup methods, snapshots are the best way to protect your files and data.

Snapshots - A standard feature in every QNAP NAS

  • Volume and LUN snapshots

    Protect your NAS folders, files, and iSCSI LUNs.

  • Block-based snapshots

    Supports incremental backups that save space by only copying modified data.

  • Versioning

    Regularly create snapshots to lower the risk of data loss.

  • Restore in a click

    Revert the entire volume/LUN or only restore specified files and folders.

Advanced snapshot features

  • Auto-snapshot before RTRR/rsync backup

    Automatically take a snapshot of a volume/LUN before backup via RTRR/rsync, even if the file is in use.

  • Snapshot Agent utility

    The Snapshot Agent utility helps servers create consistent snapshots for Microsoft® VSS and VMware® vSphere™ Client.

  • Snapshot Vault

    Centrally stores snapshots from multiple NAS. Remote snapshots can be cloned as a local volume for data access.

  • Guaranteed snapshot space

    Reserve dedicated space for storing snapshots (the default value is 20%) to ensure you have sufficient space for new snapshots.

  • Snapshot clone

    Quickly clone a volume/LUN snapshot from the Snapshot Vault as a volume or iSCSI LUN on a QNAP NAS without interrupting current system operations.

Mitigate the growing threat of ransomware

Ransomware attacks continue to increase, and they indiscriminately target businesses, infrastructure, the public sector, non-profit organizations, and home users. QNAP NAS includes comprehensive backup features and supports point-in-time snapshots to help protect and restore important files/data and avoid downtime. If ransomware attacks or an unexpected situation arises on your system, simply revert your affected files or the entire system to the previous state that the snapshot has recorded.

  • Step 1

    Regularly update, and use Malware Remover

    Keep the NAS operating system and apps updated to the latest version and regularly scan your NAS using the latest malware definitions. If infected files are detected, they will be immediately removed to enhance NAS data security.

  • Step 2

    Routinely back up to your NAS, and create multi-version snapshots

    If your computers are infected by ransomware or any unexpected corruption occurs, snapshots can be used to instantly restore your data.

  • Step 3

    Back up snapshots to another QNAP NAS

    Snapshots offer protection in the event of ransomware attacking via your PC. You can double your data protection by back up snapshots to another QNAP NAS.

Snapshot Overview

Manage your snapshots with a professional and detail-driven interface. All the snapshot versions and the time of your latest snapshot are precisely recorded.

Snapshot Replica

View the snapshot backup jobs of a shared folder/LUN, including destination, schedule, last finish/next start time, and progress information.

Snapshot Vault

Centrally store snapshots from other NAS.

Browse snapshots content

Browse all of the snapshot versions and identify differing content using the File Station Snapshot Directory.

Instant snapshots and real-time SnapSync

Near-limitless and lightweight snapshots. (Supported by QuTS hero and QES operating system)

Restore snapshots locally or remotely

  • Restore and clone

    Revert an entire volume/LUN in seconds or clone a volume/LUN snapshot as a volume or iSCSI LUN on a NAS. Restoring specified files and folders is also easy.

  • Multiple destination

    Snapshot content can be quickly restored to the local NAS or restored on a folder/file basis to a local/remote NAS or cloud storage.

  • Restore at client side

    Users can quickly view the recent snapshots directory in each shared folder via SMB/CIFS/AFP to copy and restore data from snapshots.

  • Remote restoration

    Remote backup and restoration enables double protection for minimal downtime. You can directly restore snapshot backups in a remote NAS to ensure continuity if the local NAS cannot function, or clone a volume/LUN snapshot as a volume or iSCSI LUN on the remote NAS.

Snapshot space management and reservation strategy

A QNAP NAS will enter protection mode (where no more data can be written) if the available free space is less than 16GB. When using snapshots, you should use snapshot space management to prevent this situation from arising.

Strategy 1: Activate smart snapshot space management

Storage & Snapshots Manager supports smart snapshot space management - “Delete all snapshots” or “Preserve minimum snapshots”. These actions will be automatically performed if usable NAS storage is less than 32GB. With these settings, the NAS will avoid entering protection mode and maintain stable operations.

“Preserve minimum snapshots” will keep at least one snapshot file for each version control duration for snapshot recovery usage. However, it is still possible that NAS enters read-only protection mode if the preserved snapshot file size exceeds 16GB.

Strategy 2: Use thin volumes

QNAP NAS operating systems support thin and thick volumes. As thick volumes allocate the total size of the volume upon creation, this can cause snapshots to require larger space and may lead to insufficient available pool space. On the other hand, snapshots with thin volumes only use space as needed and prevent ineffective storage utilization. Learn more

Snapshots with thick volumes require larger usable storage space (up to 40% of total storage) to ensure stable applications.

Thick Volume Thin Volume Static Volume
Benefits Higher performance than thin volumes. Reserves the total usable storage. Smaller snapshot file size. Highest storage utilization efficiency. (Mainstream approach) Best overall read/write performance.
Note
  • Requires precise storage allocation to prevent spare/wasted storage.
  • Larger snapshot files use storage space very quickly. (Smart snapshot space management is recommended.)
  • Lesser performance than thick volume.
  • Requires regular checks on usable storage (it is recommended to set a Storage Pool Alert Threshold).
  • Does not support advanced features including snapshots, caching, and self-encrypting drives (SED).

Windows Previous Versions support

Snapshots enable Windows® users to restore files directly from File Explorer simply by right clicking on files, saving time and effort without requiring help from IT staff.
