Without application consistency, restored data might be corrupt or incomplete, rendering the application unusable.

  • Data Integrity

    Application-consistent backups guarantee data integrity within the application. For example, a database backup taken without application consistency might capture data mid-transaction, leading to an inconsistent state upon restoration. Application-consistent backups use mechanisms like VSS (Volume Shadow Copy Service) on Windows or pre- and post-scripts on Linux to quiesce the application before taking the backup, ensuring a complete and usable data set. This integrity is crucial for successful application recovery.

  • Crash Consistency vs. Application Consistency

    Crash-consistent backups capture the state of the virtual machine at the moment of backup, which may leave applications in an inconsistent state if they were actively processing data. Application-consistent backups, through methods like VSS or application-specific scripts, ensure a clean shutdown of the application before the backup, preserving data integrity. Restoring a crash-consistent backup might require database repair or other recovery procedures, whereas an application-consistent backup generally avoids such complexities.

  • Impact on Recovery Time Objective (RTO)

    While application-consistent backups ensure data integrity, they might slightly increase the backup window due to the time required to quiesce the application. However, this small increase in backup time significantly reduces the recovery time objective (RTO) by eliminating the need for extensive post-restore recovery procedures. The ability to quickly restore a fully functional application minimizes downtime and its associated costs.

  • Backup Methods and Application Consistency

    Different backup methods offer varying levels of application consistency. Agent-based backups, which install software within the guest operating system, generally offer the best application consistency. Agentless backups, operating from the hypervisor level, may rely on techniques like VSS integration or change block tracking (CBT) to achieve application consistency, albeit with potential limitations. Choosing a backup method that supports the required level of application consistency is crucial for a successful backup strategy.

Achieving application consistency is fundamental to a successful ESXi virtual machine backup strategy, particularly for business-critical applications.
