Important:
If prompted, complete 2-step verification. This is required if the destination NAS has enabled 2-step verification.

Backup Plan
Description
Scheduled
SnapSync backs up data periodically, according to a schedule.
You can set the schedule to daily, weekly, or monthly. On the day the job runs, you can set the job to run once or periodically.
Real-time
Each write operation to local storage is immediately replicated to the destination storage pool.
Manual
The job only runs when you start it manually.
- Select the destination storage pool.
-
Select the destination shared
folder or LUN.
Warning:
All data in the shared folder will be deleted.
- Optional: Click New to create a new destination shared folder.
- Optional:
Configure job options.
Setting
Description
Compression
SnapSync compresses the data before sending it to the destination. The destination NAS decompresses the data before saving it to disk. Enabling this setting can reduce transfer times if your NAS or the remote NAS has a slow network connection, or the two NAS devices are connecting via WAN.
Deduplication
SnapSync reduces the amount of storage and bandwidth needed by eliminating duplicate copies of repeated data.
Encryption
SnapSync encrypts the data during transmission to the destination NAS. The data is then decrypted before being stored at the destination.
Support application consistent snapshots
SnapSync creates application consistent snapshots.
Note:This option is only available for VMware vCenter and Volume Shadow Copy Service (VSS) aware applications running on a Windows server. You must install QNAP Snapshot Agent on the iSCSI initiator.
- Click Next.
-
Set the source and destination network adapters for this job.
Adapter Setting
Description
Auto-Select Network Adapter
QuTS hero automatically selects the fastest network adapters at the source and destination for this job.
If either network adapter becomes disconnected, QuTS hero will select the fastest available adapter.
Manual-Select Network Adapter
Manually select the network adapters at the source and destination for this job. You can also select failover adapters, which the job uses if the either primary adapter becomes disconnected.
Note:The adapter lists are automatically filtered to only display adapters that can connect to the currently selected adapter.
- Click Next.
-
Configure the latency monitor.
Note:
-
This setting is only available for real-time SnapSync jobs.
-
Latency Monitor monitors the latency of the SnapSync job to ensure the job is running normally. If the job latency goes over the threshold six times within a minute, QuTS hero issues a warning notification.
- Enable Latency threshold.
-
Set a threshold value, in milliseconds. The value must be 1–5000.
Tip:
To determine the threshold value, run a SnapSync performance test by clicking Create a Performance Test. To view the average latency in previous performance tests, click Performance Report.
-
- Click Next.
- Optional:
Select Execute backup immediately.
When selected, the job will run immediately after it has been created.
- Click Create.
