What does FILE_OPEN_FOR_BACKUP_INTENT mean on an IRP_MJ_CREATE of a file (as
opposed to a directory)? It is a normal FILE_OPEN of an existing file. Does
it have any implications for a FSFD? Thanks.
Other than the obvious where if your filter opens the file itself that it
propagate that bit to its opens. This will prevent the FSD from updating
last access and possibly not bringing an offline file on to disk.

What does this flag signal the file system to do - take the file offline after it is closed or something like that? Thanks.

It tells the system to check the backup and restore privilges when doing the
access checks. These privilges override the normal access checks.

This operation will be failed by Io even before the FSD if the process has
no SeBackupPrivilege.
But, if the privilege is OK, the IRP is delivered to the FSD, and NTFS
ignores the ACL completely, just checks that there is no write desired
access.
