Availability Challenges
Data Integrity
- Software/hardware failure induced corruption to data.
- Regular database checks.
- Plan for recovery
- Resources to restore another copy, high speed of dbcheck
- Operating System failure
- Plans to failover data to another server.
- Registry switchover capability in ver 3.0
Disaster recovery
- Similar issues as data integrity
- Power Backup systems, Geographical proximities
- Multi-site, off-site storage.
Operator/User Stupidity Proof
- Accidental deletion of data. (oops!)
- Provision to snap-shot data and keep in cold storage(offline)
