“RTRR Make Backup More Efficient”
Real-time Remote Replication (RTRR) is an exclusive and powerful backup feature provided by QNAP NAS to back up new and modified files immediately to another folder (on the local NAS or an external drive) or a remote NAS. RTRR improves backup efficiency and reduces backup time. It also supports data backup from the NAS to a remote FTP server and vice versa.
- Configure the settings on the remote RTRR server (QNAP NAS)
- Configure the job settings on the local NAS
1. Login to NAS as an administrator and go to “Applications” > “Backup Server”.
2. Under the “RTRR Server” tab click “Enable Real-time Remote Replication Server”.
3. The default service port is 8899; you do not need to change the port number.
4. Enter a password for RTRR backup and verify the password, then click “Apply”.
Note: To synchronize files to a local folder or using the FTP protocol, you do not need to enable RTRR server.
1. Go to the “Backup” > “Remote Replication”.
2. Under the “RTRR” tab click “Create New Replication Job” to open the wizard.
3. Click “NEXT”.
4. Select the sync locations. You can choose to back up data from:
(1) Local folder to remote folder
(2) Remote folder to local folder
(3) Local folder to local folder or external drive
In this example we select “Local folder to remote folder” to replicate files from the local NAS to a remote NAS. Click “NEXT” to continue.
5. Enter the IP address of the remote NAS and the RTRR password configured on the remote NAS (“Application Servers” > “Backup Server”) Click “NEXT” to continue.
6. Select the source folder for backup and the target folder. To add more folder pairs for backup, select “Add More Folder Pairs”. Click “NEXT”.
7. Select “Real-time” as the backup mode and click “NEXT”. You can also select “Schedule” and configure the backup schedule. Note that real-time synchronization is only supported by real-time mode. To configure backup policy and filter to increase data transmission efficiency, click “Configure policy and filter”.
8. When real-time mode is selected, you can enable and configure the following policies:
(1) Detect sparse files
(2) Ignore symbolic links
(3) Extended attributes
(4) Compress files during transmission
Click “NEXT” to continue.
9. Specify the criteria for the following items as you wish. Only the files which match the criteria will be replicated.
(1) File size
(2) File date/time
(3) Included file types
(4) Excluded file types
Click “NEXT” to continue.
10. The sync job name is generated automatically. You can modify the name as you wish. Click “NEXT”.
11. Review the configuration and click “NEXT” to continue.
12. Click “FINISH” to close the wizard.
The target host and the replication job name will be shown on the list. The status column displays “Standby”, which means the folder is being monitored. Any changes to the source folder will be replicated to the remote server immediately.
