Upgrading Cassandra from NetBackup 10.0
Cassandra support is added from NetBackup 10.0 with CLI support only and with policy-based backup and restore. NetBackup 10.1 and later releases have Cassandra support using NetBackup APIs and web UI. It is based on protection plan methodology. As NetBackup 10.1 does not support backups or restores using CLI, NetBackup only support restore of old backup images using the restore CLI.
When upgrading from NetBackup 10.0, if you have policies for Cassandra backups, do the following:
You must delete these policies.
Stop taking backups using the CLI as they are not supported.
Configure the DSS and Apache Cassandra cluster from the WebUI and start with a fresh backup schedule.
Ensure that the primary, media, clients are on NetBackup 10.1 or later. Back-level media or clients are not supported for Cassandra in NetBackup 10.1.
When you restore old backup images of NetBackup 10.0, ensure that you have the Cassandra clusters and staging cluster configured by web UI. In addition you need to make the tpconfig settings for the Cassandra cluster as in NetBackup 10.0. Review the restore section from NetBackup 10.0 Cassandra admin guide. You require tpconfig based configuration of the target Cassandra cluster. If you have all the credentials and configuration already done for the target Cassandra cluster by tpconfig you can start doing a restore. If you do not, then follow the steps:
Ensure that you have the credentials of the target Cassandra cluster. Refer to NetBackup 10.0 admin guide for details. Adding Cassandra credentials in NetBackup
Ensure that the Pre-requisites are met for the restore Pre-requisites for Cassandra Restore.
Do the Cassandra configuration if the target Cassandra was not already configured. Refer to Configurations for Cassandra Restore.
Ensure that you are create the selection and rename file based off a supported restore combination listed in the Restore combinations.
