[Samba]NT ACLs and backup.

[David Brodbeck]

Are you using an ACL-enabled filesystem, or just letting Samba map ACLs onto
standard UNIX privilages?

If it's the latter, any UNIX backup tool should back them up.  If it's the
former, you'll need a tool that understands the filesystem ACLs.

Hi,

I new to Samba and I have a couple of questions about how it handles NT ACLs
(Access Control Lists).

I tried searching the archives but couldn't find anything relevant.  If this
is documented somewhere, please point me at the relevant docs.

I'm pretty sure Samba allows a NT client to set the security ACLs.

My question is what happens if:
   I setup an entire Linux Volume to be an SMB share
   I backup my Linux based SMB folder to tape via tar, cpio, or whatever
   I do a "rm -rf" on the Linux Volume
   I restore my backup from tape.

Will I get the NT ACLs restored.  (I'd be surprised if the answer is no.)

Now I delete just a single file, and then I do a single file restore.

Do I get it's ACL info restored?  It seems unlikely to me, but I don't know
where this metadata is stored.

===
New scenario.

I use smbclient to create a tar backup of an externally served SMB share.

When I do a restore, do I get the ACLs restored?

(I tried this with V2.2.1, but I did not get them.  Maybe I did something
wrong.)

Thanks for any clarification regarding the above.
