Backing up and restoring IBM Software Hub
IBM Software Hub supports online and offline backup and restore.
- Online backups
- During an online backup, normal runtime operations in the IBM Software Hub cluster continue while the backup is taken. Container Storage Interface (CSI) volume snapshots of Kubernetes metadata and volume data are taken with minimal disruption.
- Offline backups
- During an offline backup, IBM Software Hub
services are quiesced to bring them to a consistent state. At the beginning of the backup process,
each service stops using its data volumes until the backup is completed. External operations for
services that participate in the backup are interrupted for the entire duration of the quiesce,
backup, and unquiesce steps.
You can create offline backups in the following ways:
- Create Restic backups on an S3-compatible object store of Kubernetes metadata and volume data.
- If you are using Portworx storage, create snapshots of volume data.
- Create backups of volume data on a separate Persistent Volume Claim (PVC) or S3-compatible object store.
Because large volumes of data result in significant down time during offline backup and restore, it is recommended that you do online backup and restore.
Except for IBM Software Hub deployments that use the following types of persistent storage, offline backup and restore will no longer be supported in a future release.
- NFS
- Offline backup and restore to the same cluster or to a different cluster by using Kopia backups will continue to be supported.
- Amazon Elastic Block Store
- Offline backup and restore to the same cluster by using Kopia backups will continue to be supported.
- Amazon Elastic File System
- Offline backup and restore to the same cluster by using Kopia backups will continue to be supported.
Online backup and restore with NetApp Astra Control Center is replaced by NetApp Trident protect.
Deciding how to back up and restore your data
Use the following questions to help you decide which approach to take to back up and restore your IBM Software Hub services and data.
| Question | What to do |
|---|---|
| What backup and restore options are available? | See Supported backup and restore scenarios to find out the different ways that you can back up and restore IBM Software Hub. |
| What storage type are you using? | Review Supported storage types to find out what backup and restore options are available for the storage type that you are using. |
| Do the services that I am using support backup and restore? | See Services that support backup and restore to find out if the services that you installed support backup and restore. |
| What if I only want to back up and restore a specific service? | Some services support exporting data from one IBM Software Hub installation and importing the data in another installation. |
Supported backup and restore scenarios
The following backup and restore scenarios are supported.
- Online backup and restore
-
- Back up and restore a IBM Software Hub instance project (namespace) on the same cluster by using CSI snapshots
- Back up and restore a IBM Software Hub deployment (IBM Cloud Pak foundational services and IBM Software Hub operator project, IBM Software Hub instance project) to a different cluster by using CSI snapshots
- Offline backup and restore
-
- Back up and restore a IBM Software Hub instance project on the same cluster by using CSI snapshots or Restic backups
- Back up and restore a IBM Software Hub deployment (IBM Cloud Pak foundational services and IBM Software Hub operator project, IBM Software Hub instance project) to a different cluster by using Restic backups
- Back up and restore a IBM Software Hub instance project's volume data to the same instance on the same cluster by using volume snapshots or backups
Supported storage types
The following table shows the storage types that IBM Software Hub supports that are also supported by each backup and restore method. Columns are organized by the products that you can use to back up and restore IBM Software Hub:
- IBM Software Hub OpenShift® APIs for Data Protection (OADP) backup and restore utility
- IBM Fusion backup and restore
service
If you use the IBM Fusion backup and restore service, always install the latest hotfix:
- Portworx asynchronous disaster recovery method
- NetApp Trident protect

Backing up and restoring service data
You can also back up and restore the data for a specific service by exporting a service's data and metadata from one IBM Software Hub installation and importing the data to another IBM Software Hub installation. For more information, see Migrating data between IBM Software Hub installations.
