<p>Creates a backup of an existing Amazon FSx for Windows File Server file system, Amazon FSx for Lustre file system, Amazon FSx for NetApp ONTAP volume, or Amazon FSx for OpenZFS file system. We recommend creating regular backups so that you can restore a file system or volume from a backup if an issue arises with the original file system or volume.</p> <p>For Amazon FSx for Lustre file systems, you can create a backup only for file systems that have the following configuration:</p> <ul> <li> <p>A Persistent deployment type</p> </li> <li> <p>Are <i>not</i> linked to a data repository</p> </li> </ul> <p>For more information about backups, see the following:</p> <ul> <li> <p>For Amazon FSx for Lustre, see <a href="https://docs.aws.amazon.com/fsx/latest/LustreGuide/using-backups-fsx.html">Working with FSx for Lustre backups</a>.</p> </li> <li> <p>For Amazon FSx for Windows, see <a href="https://docs.aws.amazon.com/fsx/latest/WindowsGuide/using-backups.html">Working with FSx for Windows backups</a>.</p> </li> <li> <p>For Amazon FSx for NetApp ONTAP, see <a href="https://docs.aws.amazon.com/fsx/latest/ONTAPGuide/using-backups.html">Working with FSx for NetApp ONTAP backups</a>.</p> </li> <li> <p>For Amazon FSx for OpenZFS, see <a href="https://docs.aws.amazon.com/fsx/latest/OpenZFSGuide/using-backups.html">Working with FSx for OpenZFS backups</a>.</p> </li> </ul> <p>If a backup with the specified client request token exists and the parameters match, this operation returns the description of the existing backup.
