Overview

IBM® Netezza® Performance Server for IBM Cloud Pak® for Data as a Service supports full, differential, and cumulative backups that you might run on demand or according to a schedule. If you want to run differential and/or cumulative backups, run a full backup first. If you want to restore differential and/or cumulative backups, restore a full backup first.

You cannot backup (nzbackup) and restore (nzrestore) external data source objects.

Scheduled backups

A scheduled backup is a backup of the existing database that runs on a schedule.

You can configure your backup schedule based on the following factors.

  • Frequency (in order of priority)

    1. Monthly
    2. Weekly
    3. Daily

  • Level (in order of priority)

    1. Full
    2. Differential
    3. Cumulative

If there is a schedule overlap, you are notified about it. You also receive information about which schedule takes precedence and why. You cannot schedule backups for the same frequency to start at the same time if there is any intersection of databases between the backup schedules. If there is no preexisting full backup to reference, you cannot perform a differential or cumulative backup.

On demand backups

An on demand (ad hoc) backup is a backup of the existing databases that runs only once and on demand. You can create on demand backups before you do any alterations on your system.

On demand backups support different backup levels:

  • Full
  • Differential
  • Cumulative

Destination buckets

To create backups, you must have a destination bucket setup created.

For NPSaaS, you can choose between the following destinations.

  • Amazon S3
  • Azure Blob Storage
  • IBM Cloud Object Storage

Creating destination buckets

You can create a destination bucket for Amazon S3, Azure Blob Storage, and IBM Cloud Object Storage by using the web console.

For Amazon S3
