Snapshot Vault
Snapshot Vault is an essential component of a comprehensive data backup strategy for organizations with a global footprint aiming to achieve a boundary-less
datacenter. Snapshot Vault is your backup center for storing and managing every snapshot created remotely from another QNAP NAS. Snapshot Vault fully supports
cloning a snapshot.
Use the Clone function to clone (or mount) a snapshot from the Snapshot Vault as a volume or iSCSI LUN on a QNAP NAS. Directly access these les through File
Station or Backup Station. Use an iSCSI initiator to connect to a cloned iSCSI LUN from another computer.
Managing snapshots remotely from another NAS
To minimize the risk of data breach, the Snapshot Replica provides the option of le encryption. It also provides le compression and transfer rate adjustment to lower
bandwidth consumption.
Replication settings
Snapshot Agent, used for iSCSI LUN, allows connecting the Turbo NAS with the remote servers (VMware vCenter or Windows Server) to ensure consistent snapshots.
On those remote servers, the running applications (VMware virtual machines, Hyper-V virtual machines, SQL server, Windows le server…) will write/ush the data
from the memory to the iSCSI LUN prior the snapshot is taken. The application will then be consistent and include all necessary data. In case of snapshot restoration,
no data will be missing.

The backup software sends
a snapshot request to Windows
Turbo NAS receives the request and
takes a snapshot for iSCSI LUN
Turbo NAS sends back the snapshot for Backup software to conduct the backup job
Windows VSS ushes the data to iSCSI LUN and
