Backup and restore planning

Plan resource requirements for backups.

The backup resource planning depends on application size, frequency of backups, and retention settings. Application(s) size and backup frequency is the amount of additional network and remote S3 Object capacity required. Also, the backup retention policy has an impact on the overall S3 Object capacity consumed.

For example, you have an Application A that is consuming 2 TB of data. It has a daily backup policy with 7 days retention policy that means you need 2 TB of network traffic daily and 14 TB of S3 Object capacity.

IBM Storage Fusion supports backup and recovery operations on Red Hat® OpenShift® Container Platform environment on AMD64 with any storage provider that implemented the IBM Storage Scale Container Storage Interface Driver and meets the following prerequisites:
  • The IBM Storage Scale Container Storage Interface Driver driver must be v1 or higher (no support for alpha or beta versions)
  • The IBM Storage Scale Container Storage Interface Driver driver must support Volume Snapshot and Restore.
  • StorageClass must be created with volumeBindingMode: Immediate (volumeBindingMode: WaitForFirstConsumer is not supported)
  • PersistentVolume (PV) must be created with volumeMode: Filesystem (volumeMode: Block is not supported)
Note: It is also recommended that the VolumeSnapshotClass deletion policy is configured to delete snapshots after the corresponding VolumeSnapshotContent is deleted (deletionPolicy: Delete).
