ITIL – Storage Backups Best Practices
June 23, 2012Best Practices:
1) Periodic backups of servers; periodic backup of application and database servers (os platforms and application files – not data) should be performed and shipped to an offsite location.
2) These backups can be either tape-based backups or backup to disk (based on the discretion of the service delivery teams).
3) Full backup should be performed at least monthly. It’s is recommended that incremental backups occur daily until changes to the systems and their configurations become infrequent – at which time it will be acceptable to perform weekly incremental backups,
4) Snapshot of EMPI data; Where possible, 24 worth of local snapshots of changes to data (stored on SAN / NAS storage) should be maintained in 15 minutes increments to ensure that rollbacks of corrupted data can meet stated RPO requirements (assuming that the corruption is detected),
5) Replication of EMPI Data to alternative Data Center.
