Reconfiguring or adding backup settings after installation of the management subsystem on OpenShift and Cloud Pak for Integration

You can reconfigure the backup settings after installation of the management subsystem on OpenShift and Cloud Pak for Integration.

oc edit apiconnectcluster <name-of-instance>

1. Make sure that the management cluster status is Running and the READY condition displays the same value before and after the "/".

   For example:

   oc get mgmt
   NAME   READY   STATUS    VERSION      RECONCILED VERSION   AGE
   mgmt   16/16   Running   10.0.1-eus   10.0.1.1-eus-0-eus       19h

2. Create backup secret for your backup type. See the appropriate instructions:
   • Configuring S3 backup settings for a fresh install of the Management subsystem on OpenShift or Cloud Pak for Integration
   • Configuring SFTP backup settings for fresh install of the Management subsystem on OpenShift and Cloud Pak for Integration

     Note that SFTP backups settings are not supported on v10.0.1.0 or earlier.

3. Complete the following steps, based on your storage type:
   • S3 storage

     In 10.0.1.0 and later, you can change or add the DatabaseBackup s3 configuration via the Management section of the API Connect Cluster CR after a fresh install. However, doing so requires a reconfiguration of the database and a brief downtime. The operator restarts the database with the new backup configurations as soon as the new configuration in the management CR is saved.

     spec:
       management:
         databaseBackup:
           protocol: objstore
           s3provider: ibm
           host: s3.eu-gb.cloud-object-storage.appdomain.cloud/eu-standard
           path: apic-backup
           credentials: mgmt-backup-secret
           schedule: "0 3 * * *"
           restartDB:
             accept: true

     Note: Version 10.0.1.0 only: The CR entry does not contain the protocol setting:

     
     databaseBackup:
       s3provider: ibm
       host: s3.eu-gb.cloud-object-storage.appdomain.cloud/eu-standard
       path: apic-backup
       credentials: mgmt-backup-secret
       schedule: "0 3 * * *"
       restartDB:
         accept: true

     Configuration of s3 backups uses a new parameter restartDB that is required when changing the backup configuration. restartDB is not required for initial deployments, only for modifications after the cluster is deployed.

     Table 1. Additional parameter for S3 backup type reconfiguration

     Parameter

     Description

     restartDB:    accept: <value>

     Required when changing the backup configuration. The parameter accept is a boolen: <value> can be true or false. When accept is true, and a new configuration for management CR is saved, the operator: Stops the database and any dependent services Applies the change Restarts the stopped components. Note: restartDB is not required for initial deployments, only for modifications after the cluster is deployed.

     Note: Reconfiguration on v10.0.1.0 only:

     The operator must create an upgrade CR, because the postgres database is re-created as part of database backup configuration change. The new upgrade CR goes to Complete as soon postgres comes up.

     Example: When you change database backup configurations after upgrading API Connect from v10.0.0.0-ifix2 to v10.0.1.0, the operator restarts the postgres database-related components. The operator also creates an upgrade CR, and reaches the Complete state as soon as all postgres database components (pgbouncer, postgres database) are in Running state:

     NAME                                                            STATUS     MESSAGE                                                    A
     GE
     managementdbupgrade.management.apiconnect.ibm.com/m1-up-g6lcb   Complete   Upgrade is Complete (DB Schema/data are up-to-date)        1
     6m
     managementdbupgrade.management.apiconnect.ibm.com/m1-up-zqkk5   Complete   Fresh install is Complete (DB Schema/data are up-to-date)
     63s5s
     

   • SFTP (Version 10.0.1.1-eus or greater only)

     In v10.0.1.1-eus and greater, you can change/add the DatabaseBackup SFTP configuration via the Management section of the API Connect Cluster CR after a fresh install. This process does not involve any downtime. The same backup settings are used for reconfiguring as for initial configuration. For complete description of backup settings, see Configuring SFTP backup settings for fresh install of the Management subsystem on OpenShift and Cloud Pak for Integration.

     spec:
       management:
         databaseBackup:      
           protocol: sftp
           host: <SFTP-hostname>
           port: <SFTP-port> (Optional, default is 22)
           path: apic-backup
           retries: 0
           credentials: mgmt-backup-secret
           schedule: "0 3 * * *"
     

     Note: Handling of SFTP backup taken on v10.0.1.0.

     In v10.0.1.0, you can manually send backup tar files to an SFTP server, as described in Uploading backup files to an sftp server.

     You can upgrade from v10.0.1.0 to v10.0.1.1-eus, and configure SFTP backup settings, as described previously in SFTP.

     API Connect resyncs upstream SFTP backups and creates relevant backup CRs of type record.

     Note that the latest local backup is also automatically uploaded to the SFTP server if it was not uploaded to SFTP in v10.0.1.0.
