To minimize vRealize Operations Manager downtime and data loss in the event of failure, back up regularly. If your system fails, you can recover it by restoring to the last full or incremental backup.
You can back up and restore vRealize Operations Manager single-node or multi-node clusters by using backup tools. You can perform full or incremental backups and restores of virtual machines.
Guidelines for Planning Backups
- If the cluster cannot be taken offline, do not quiesce the file system.
- Use a resolvable host name and a static IP address for all nodes.
- All nodes must be in the same power state and accessible during backup.
- Back up the entire VM. You must back up all VMDK files that are part of the virtual appliance.
- Do not change the state of the cluster when the backups are in progress.
- There is sufficient disk space available for your Avamar instance. The amount of disk space needed depends on the size of the multi-node cluster that you want to back up.
- In the vSphere Web Client, verify that the virtual machines have the latest VMware Tools installed.
If you are using backup tools, such as Avamar, and have manually created vSphere snapshots of any of the VMs to be backed up, the tools delete all existing snapshots at the time of the backup or restore.
It is highly recommended to take a backup during quiet periods. Since a snapshot-based backup happens at the block level, it is important that there are limited or no changes being performed by a user on the cluster configuration. This ensures that you have a healthy backup.
It is best to take the cluster offline before you back up the vRealize Operations Manager nodes. This ensures the data consistency across the nodes and internally in the node.
If the cluster remains online, backup your vRealize Operations Manager multi-node cluster using Avamar or other backup tools, disable quiescing of the file system.
Common Backup Scenarios
The common backup scenarios for vRealize Operations Manager systems include a full backup of a single node virtual appliance system and a full backup of a multiple node virtual appliance cluster.
Single-Node Virtual Appliance
- Assign a static IP address.
- Ensure that the power is on for the entire backup process.
Multiple-Node Virtual Appliance Clusters
To back up multiple-node virtual appliance clusters.
- Assign a static IP address for each node.
- Ensure that all nodes that are configured with high availability are accessible and are configured for high availability.
- Ensure that the power remains on during the entire backup process.
