Backup and DR Service for IBM Db2

Db2 is a is a family of relational database management systems within IBM's Information Management division that is centered on several relational database management system offerings. This section explains how to protect Db2 application consistent database data with Backup and DR in Linux environments.

Protection method

Db2 uses WRITE SUSPEND and WRITE RESUME (Persistent Disk snapshot backup) for both primary and secondary Db2 databases on a Compute Engine instance to incrementally back up data and log volumes from your Persistent Disks with application consistency.

Backup and DR stores multiple copies of each snapshot across multiple locations with automatic checksums to ensure the integrity of your data.

The following are Db2 backup APIs used by Backup and DR:

  • Standby (HADR) database: The Db2 database deactivate and Db2 database activate API are used for freeze and thaw.

  • Db2 log backup: Logs are flushed using Db2 archive log for database. During a log backup, the payload of the log segments is copied from the log area to the location specified by the parameter logarchmeth1.
