Manual: Enabling the Backup on the Cluster

Note:

• Before continuing, make sure you have followed the Prerequisites.
• These steps will not enable the backup of external data sources, such as the SQL Server. You must enable external data source backup separately.

Enabling the Backup on the First Server Node

You must enable data volumes from any server machine, as the data is replicated across all the server nodes in the cluster. Therefore, the command to enable the backup on the first server node is different from the one used for enabling the backup on the remaining server nodes. Data volume backup is done by a periodic cron job, which can run on any of the nodes decided by Kubernetes.

To enable the backup, the backup.json file, which contains backup configuration, is required. For details, see Preparing the backup configuration.

To enable the backup on the primary node of the cluster, run:

./install-uipath.sh -i backup.json -o output.json -b --accept-license-agreement

Note:

• Even when this node is lost, you do not have to run this command again on the new replacement node. Kubernetes will always schedule data volume backup on any of the nodes.
• You do not need to enable the backup on any of the agent nodes, as there is no etcd or data volumes on these nodes.

Enabling the Backup on the Remaining Server Nodes

To enable the node configuration (etcd) backup on all the remaining server nodes, take the following steps:

1. Copy the backup.json file from the first server node to all remaining server nodes.
2. To enable the etcd backup, run:

   ./install-uipath.sh -i backup.json -o output.json -b -j server --accept-license-agreement
