Crash-consistent snapshots can help you recover data and work well\nfor a majority of applications. However, some data in storage might be\noutdated at the time of recovery because it's kept in operating system and\napplication caches for some time before it's written to storage.\n\nCreate an application-consistent snapshot\n-----------------------------------------\n\nWe recommend that you synchronize snapshot creation with dedicated recovery\npoints of your application. To use NetApp Volumes snapshots to\ncreate application-consistent snapshots, complete the following actions:\n\n1. Flush all unwritten data from the application caches to storage. Many\n applications, such as databases, provide built-in mechanisms for this\n procedure. Consult your application documentation for more information.\n\n Alternatively, you can stop the application briefly.\n2. Take a snapshot of the volume. Snapshots take a few seconds to generate.\n\n3. Return your application to its normal state of operation.\n\nThis procedure lets you create consistent snapshots of large application\ndatasets within a few seconds.\n\nWhat's next\n-----------\n\n[Manage your snapshots](/netapp/volumes/docs/configure-and-use/volume-snapshots/manage-snapshots)."]]
