- If your workload is performance sensitive and can tolerate recovery from crash-consistent backups, crash-consistent backups help quiesce VM I/O for a shorter period during backup. Crash-consistent backup doesn't use Volume Shadow Copy Service, (VSS) (for Windows) or *fsfreeze* (for Linux) to avoid the associated quiescing delays.

- If you don't want to install the VM Agent or snapshot extension required for application-consistent or file-system-consistent snapshots in your Azure VM, use crash-consistent backups for an agentless backup solution.
