Disaster Recovery

Business critical applications should be built in multiple data centers, with failover tested and verified prior to a disaster situation.

SafeHaven Disaster Recovery

Often business critical applications require clearly defined Recovery Point Objective (RPO) and Recovery Time Objective (RTO) times. CenturyLink SafeHaven enables protection of critical applications from unexpected unavailability. Additionally, SafeHaven offers advanced features like Live Failback, Live Test Failover, Custom Check Point Intervals, Protection Groups, and Runbook Automation.

Database Backup

Cloud Server backups do not allow for a crash consistent database backups due to the nature of their design (in-flight transactions etc.). To mitigate this, there are two recommended methods to achieve crash consistent database backups on the platform.

  1. Leverage integrated database backup tool kits that ship with database software such as Oracle RMAN or SQL Maintenance. These tools create backups of logs and databases to localized or remote volumes in a scheduled manner. Typically, localized database volume backups are acceptable for smaller environments. Larger database environments may benefit from implementing a storage server, accessible via CIFS or NFS, to centrally house all database backups. There are numerous 3rd party database backup products available that can also be leveraged in this fashion.
  2. For Microsoft SQL environments, the option to use 3rd party backup software backed by Object Storage is available. These tools typically allow for hot backups using VSS of SQL server transaction logs and databases to a centralized repository. Clients can control the frequency of database backups (including logs) and can achieve very aggressive recovery point objectives (RPO) and recovery time objectives (RTO) for their mission critical SQL database services.
