Installation prerequisites for backup servers

Edit online

For hosts that are used as a backup server, the operating system version and maintenance level must be the same as the production server

Backup server requirements

To run the software, the following settings are required on the backup server:

  • The user name and group name of the application owner on the production server must be available on the backup server. The same user ID (UID) and group ID (GID) must be used.
  • A database instance with the same version as the database instance on the production server must be installed on the backup server.

When IBM® Storage Protect Snapshot is used in an environment with IBM Storage Protect, a backup server is required. This backup server is used to offload the backup workload from the production server to the backup server and sends the application critical backups to an IBM Storage Protect server.

The IBM Storage Protect backup-archive client is used by these clients and must be installed and configured on both the production and the backup servers.

Update the IBM Storage Protect backup-archive client node password on the production server and all backup servers whenever it changes. When IBM Storage Protect is configured to use the PASSWORDACCESS GENERATE parameter, the password can change without notification.
  • If the IBM Storage Protect backup-archive client is configured to use the PASSWORDACCESS GENERATE parameter, use the IBM Storage Protect proxy-node capability to avoid authentication errors when the password is reset.
  • Create one data node on the IBM Storage Protect server where all IBM Storage Protect clients from all backup and production servers are sending and retrieving data.
  • Create one authentication node for each production server and backup server that is configured as proxy node to this data node.
