Installation prerequisites for backup and clone servers

Edit online

For hosts that are used as backup or clone servers, 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 user ID (UID) for the clone instance must be different from the owner of the production database when the name of the clone database instance is different from the name of the production instance.
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 following IBM Storage Protect Data Protection clients are used by IBM Storage Protect Snapshot to start a backup to the IBM Storage Protect server, and must be installed and configured on the backup server.

IBM DB2® Storage Protect client for DB2 environments.
IBM Storage Protect for Enterprise Resource Planning agent is optional for DB2 in an SAP environment.
IBM Storage Protect backup-archive client, which is used to offload backups from the DB2 standby 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.

For FlashCopy® cloning, the database instances must be installed and configured on the clone server.

IBM Storage Protect Snapshot requires the following settings for cloning:

DB2 and DB2 in an SAP environment: Two database instances must be installed on the clone server. These database instances must be the same version as the database instance on the production server. One of the two database instances is assigned the same name as the production instance (on the production server). The other database instance is assigned the clone instance name. If the clone database name is the same name as the production database name, only one database instance with this common name is required on the clone server.; On the clone server, the database instance with the same name as production database instance must be assigned a user name and group name. The user name and group name must be the same names that are assigned to the database instance on the production server. The same user ID (UID) and group ID (GID) must be used. If the name of the clone database is different from the name of the production database, the user name and UID for the clone instance must be different from the owner name of the production database.
