Depending on the quiescing method used, the plug-in generates the following types of snapshots:
• |
Crash-consistent snapshots: Crash-consistent snapshots capture the volume state as it would be after a power outage. Such snapshots are not guaranteed to be free of incomplete I/O operations or data corruption. During a restore, there can be some data loss or corruption that can cause application failure. |
• |
File-system-consistent snapshots: For file-system-consistent snapshots, all file system I/O is temporarily frozen and dirty memory data is flushed to the disk before the snapshot is taken. |
• |
VSS-based application-consistent snapshots: For application-consistent snapshots, all application data in memory is written to the disk. Application-consistent snapshots reduce the amount of application-crash recovery that you must perform for VSS-enabled applications, such as SQL Server, Exchange, and SharePoint, after restoring an image-level backup. |
