QNAP Snapshots
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.
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.
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.
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.
Back up snapshots to multiply data protection
Snapshot Replica
Snapshot Replica replicates snapshot files to the Snapshot Vault on the backup NAS for version control and management. It copies only the changes made since the last snapshot, helping to save you time and bandwidth, and can be run manually or on a scheduled basis. Snapshot files can be directly recovered and used in the backup NAS.
Physical migration of huge snapshots
For initial replication, you can export the source data of snapshot files from the primary NAS to an external storage device. This device can then be physically moved and connected to the secondary NAS, allowing Snapshot Replica to run over the local network to save bandwidth and time compared to migrating via the Internet.
Easy management with Storage & Snapshots Manager
Enjoy visualized snapshot management for easily creating snapshots and restoring data to any point of time to prevent losing important data.
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.
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.
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.
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.
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.
