Disaster-recovery quality characteristics

Today's tip comes from Klaus Schmidt's High Availability and Disaster Recovery. In the book Schmidt outlines a useful list for being able to test a disaster-recovery (DR) installation:

  • Being able to activate the DR system while the primary system is active.

  • Being able to test the DR system without requiring changes to the primary system.

  • Being able to component test different aspects of the DR system.

  • Availability of workload generators, regression tests, and monitoring on the DR installation.

  • A short time frame for resynchronization after testing is completed.
