Backup and DR Service can discover and backup NFS shares on a Linux host.
Before you can run application discovery to add the NFS shares to
Backup and DR, you must have a Backup and DR Agent installed on the NFS host
Install Backup and DR agent and generate secret key
Use the following instructions to add a new Linux host to the management console:
In the management console, go to Manage>Hosts.
Select + Add Host.
In the Add Host form, enter the name and an optional friendly name. The
name of a host must start with a letter, and can contain letters and
digits (0-9). Underscore ('_') characters are not valid in host names.
Enter the IP address of the host in IP Address. Click the
plus sign (+) to add it.
In the Appliances section, select the management console managed
appliances that serve this host. If the list is long, you can use the search
field to find a specific appliance or group of appliances.
Leave Host Type as Generic.
In the Backup and DR agent settings, complete the following:
Backup and DR agent port is normally port 5106. If it is anything
else, enter the port number.
You need to supply a secret key generated on the Linux host servers
by the Backup and DR agent to initialize trusted communications
between the host and Backup and DR agent. This only needs to be
done once. If you don't have the secret key, generate one by
Install the Backup and DR agent on a Linux host.
Discover the NFS application discovery in either ways:
In the management console, click the Back up & Recover drop-down menu and select Back up, and then select All Apps.
Go to App Manager>Applications, select
Add Applications and then select All Apps.
Select the host that you added in Add NFS host section and click
Discover. After the NFS shares are discovered, you can find them
using the NFS filter in the Applications page.
