File-level recovery
The low-impact, small-sized, and user recoverable snapshots offer more benefits of storage administration compared to traditional file copies,
which are often stored as a single large data file. For instance, you can choose to recover a file in a folder or the entire folder instantly with a few
clicks.
High Flexibility
Snapshots can be used with iSCSI LUNs and Volumes in QNAP NAS and expansion units to achieve full protection. On the other hand, Snapshot
Replica allows you to transfer your snapshot to a remote QNAP NAS for backup.
Intuitive and user-friendly interface
The QNAP Snapshot provides tools in Storage Manager to help you find specific files to recover. You can easily view files and folders in a
snapshot and browse through different snapshots displayed in chronological order. In addition, file recovery just takes a few clicks, increasing
operational efficiency.
Snapshot Clone
Clone a snapshot as a volume or LUN for quick file access,
eliminating long restore times and reserving sizeable space for
storing backups.
Rsync/RTRR integration
The Rsync/RTRR functions in Backup Station automatically
detect whether the system supports Snapshots. The RTRR/Rsync
functions take snapshots of the volume before starting replication
and then back up snapshots to a remote server. This greatly
enhances data integrity.

Remote Snapshot Replica prevent data loss
Snapshot Replica
Remote Snapshot Replica enables you to replicate Volumes/LUNs between different remote servers using snapshot technology, reducing both
storage and bandwidth usage. Take a snapshot immediately or schedule snapshots to be taken at regular intervals as required. This method is
widely considered to be the most fundamental of strategies for data backup.
The system may temporarily halt operations while flushing data to the iSCSI LUN.

Qsync Central Station
Centrally manage and sync your files
and devices via your PC
Synchronization as a better file
management and collaboration ap proach
Qsync Central Station supports file synchronization between
multiple devices, and you can utilize a smart phone, tablet,
computer or webpage to browse through synchronized files. When
your computer is offline, you can edit the files offline or view
the files on the local Qsync folder, and as soon as the network
resumes, online, Qsynch will resume the data synchronization.
You can also choose to keep the files stored on your QNAP NAS
un-deleted to save the storage space of your local device.
Remotely delete shared folders to prevent
data leaks
In the event where a computer/device is stolen or lost, the
Qsync folder can be remotely erased* to ensure that sensitive or
confidential data is not accessed by unauthorized users or leaked.
Once the computer/device is recovered, Qsync can easily restore
the data that was deleted, ensuring the perfect balance between
security and convenience.
Enhance management efficiency by
monitoring equipment settings
The administrator can create default settings on Qsync Central
Station 2.0 and also apply them to Qsync clients, which helps to
not only save time and effort setting up individual clients, but
also allows administrators to monitor user settings, thereby
strengthening enterprise-wide IT management and file filtering
control and avoiding the risk of deleting files on a QNAP NAS by
mistake due to synchronization. Also, by using permission settings,
administrators can flexibly adjust individual user’s equipment
settings, where it not only retains the above advantages, but
further enhances the flexibility and convenience of the centralized
management approach.
The data will still be retained on the QNAP NAS.
