Creating a backup policy using the NetBackup Policies utility
This topic provides information about using the policies utility to create a policy for the Acropolis Cluster.
For more information, See About the Hypervisor policy type to protect Nutanix AHV VMs.
To create a Hypervisor policy:
- In the NetBackup Administration Console, in the left pane, click NetBackup Management > Policies.
- On the Actions menu, click New > Policy.
- Type a unique name for the new policy in the Add a New Policy dialog box. Click OK.
- On the Attributes tab, select Hypervisor as the policy type.
In the Destination pane of the Attributes tab, select a storage unit type from the Policy storage drop-down.
To limit the number of simultaneous jobs per policy, use the Limit jobs per policy option.
For the Hypervisor policy, to use Accelerator, select the Use Accelerator option.
Note:
Use an OST supported storage unit for using the Accelerator functionality. For example: MSDP
- On the Schedules tab, click New to create a new schedule.
Starting from version 8.3, NetBackup supports full, differential incremental, and cumulative incremental backups for AHV virtual machines.
For information about incremental backups, refer to the NetBackup Administrator's Guide, Volume I.
Note:
If you want to disable accelerator in a backup policy that has incremental schedule, it is recommended that you run a full back up immediately after making the update. You can run a full backup manually or re-enable accelerator.
Run a full backup immediately after adding incremental backup schedules to an existing backup policy. This step prevents cumulative incremental backups from running as full backups till the next full backup schedule, and differential incremental to run as full backups and subsequent differential backups to run as incremental backups.
Note:
If you enable Accelerator, include at least 2 full backup schedules:
- One full schedule with the Accelerator forced rescan option disabled
- Second full schedule with the Accelerator forced rescan enabled
Configure the forced rescan enabled schedule to run less frequently than the first full backup schedule.
For example, if the first full backup schedule runs weekly, run the second schedule (with the Accelerator forced rescan option enabled) every month. However, the best frequency for this schedule depends upon your environment.
- On the Clients tab, enter the display name(s) of the virtual machine(s).
To obtain the virtual machine name, use the VM name column on the Prism web console.
- On the Backup Selections tab, click Add and enter the following parameters and their values as follows:
Hypervisor_Type=Nutanix-AHV
The value for this parameter is fixed and cannot be changed.
Backup_Host=<Fully Qualified Domain Name>
The operating system of the backup host must be a Linux RHEL or SUSE. The backup host can be a NetBackup client or a media server, or a NetBackup Appliance.
Application_Server=<Fully Qualified Domain Name of the Nutanix Acropolis cluster>
Note:
The parameters - Hypervisor_Type, Application_Server, and Backup_Host are not case sensitive. However, their values are case-sensitive.
Multiple entries for the Backup_Host parameter is not supported.
- Click OK to save the changes.
Note:
The entries that you provide in the Clients tab and the Backup Selections tab differ based on the application that you choose to back up.
