Question
How can I set high availability for NAKIVO Backup & Replication?
Answer
High availability for the Director component of NAKIVO Backup & Replication can be set by deploying the product on a VM and leveraging VMware’s built-in High Availability feature.
Alternatively, you can move the NAKIVO Backup & Replication database to a shared folder and set a “stand-by” failover instance of the software. You can use this instance if the primary instance is unavailable.
To set up a stand-by instance, follow the steps below:
- Install the primary NAKIVO Backup & Replication copy.
- Install a secondary NAKIVO Backup & Replication copy.
- Create a shared folder that can be accessed from both machines.
- Stop NAKIVO Backup & Replication services on both machines.
- Copy the "userdata" folder from the production machine to the shared folder.
- Delete the "userdata" folder from both the production machine and the failover machine.
- Mount the shared folder to both the production machine and the failover machine. Create symbolic links to the “userdata” folder on a share. For example:
- Download and unzip PSTools, and locate the PsExec.exe utility.
- Run the command prompt as Administrator and use the PsExec.exe utility to run another command-line process from the System account:
psexec -s C:\Windows\System32\cmd.exe - Mount the shared folder as a network drive from the command line (make sure that the account that you use has read and write permissions):
net use Z: \\fileserver\share /u:domainname\username password - Create a symbolic link to disk Z: <installation path>\NAKIVO Backup & Replication from cmd:
mklink /d UserData Z: - Start NAKIVO Backup & Replication services on the production machine.
If the production machine fails, you can start NAKIVO Backup & Replication services on the failover machine.
