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
andDb2 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.
Protect IBM Db2 databases
To get started protecting your Db2 databases, go through the Db2 procedures in Protect and recover an IBM Db2 database running in Compute Engine
Backup and DR uses Persistent Disk snapshots 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.
