By default, when you delete an Amazon FSx for Windows File Server file
system, a final backup is created upon deletion. This final backup is
not subject to the file system\'s retention policy, and must be manually
deleted.
The DeleteFileSystem
action returns while the file system has the
DELETING
status. You can check the file system deletion status by
calling the DescribeFileSystems action, which returns a list of file
systems in your account. If you pass the file system ID for a deleted
file system, the DescribeFileSystems returns a FileSystemNotFound
error.
Deleting an Amazon FSx for Lustre file system will fail with a 400
BadRequest if a data repository task is in a PENDING
or EXECUTING
state.
The data in a deleted file system is also deleted and can\'t be
recovered by any means.
