ABSTRACT
One of the most important data recovery considerations is one of the most overlooked—the difference between data recovery and service restoration. Data recovery merely refers to retrieving data from protection storage, but depending on the nature of the failure, storage, and data, there may be considerably more effort involved in achieving service restoration. Most of the recommendations are focused on recovery operations from backup; that being said, many will equally apply to any data recovery operation that requires human intervention, regardless of whether it is performed out of a backup product or some other form of protection such as snapshots, continuous data protection, replication, or continuous storage availability. Similarly, when authors think of backup and recovery systems, those systems need to include a high degree of redundancy to ensure a cascading failure (e.g., a primary system failure and a protection system failure) does not prevent data recoverability.
