Re: using Windows backup API?

Traditionally, in UNIX, a root user can access any file in the system without doing anything special.

This contrasts with Windows, where even Administrator user can't read files for which he has not access permissions (i.e., a file with all permissions removed)[1].

To access such files in Windows, one needs to use a special Backup API.

The backup API is not really necessary to access such files. It's
enough to enable the SE_BACKUP_NAME privilege and to use the FILE_OPEN_FOR_BACKUP_INTENT flag in file and directory open calls.
This is partly already done in the current Cygwin release, but it
will only be done consequently in the next major release 1.7.0.
No, we don't have a release date yet.

Is there a release date yet? ;)



Feel free to test the latest
Cygwin snapshots from http://cygwin.com/snapshots/

Cool, it works! That's great!


When you write "it's partly done", are there any bits and pieces still missing in this feature?
