[Samba] Large-scale ACL copying?

[Andrew Furey]

Hi all,

Well, I'm getting somewhere I think, I now have both ACL support and 
domain login basically working. However I'm at a bit of a loss as to how 
to proceed.

Basically I want to copy over a large number of files and directories 
(~300k files, ~60Gb total) from an existing W2k server to a Samba 
server. These files have existing ACLs set, so I need to preserve them 
somehow.

I can of course copy over the files themselves using any number of 
methods "from" either machine, but the majority of them don't have any 
knowledge of ACLs at all. I've been trying to use xcopy /o, but it gives 
"Access Denied" and a file size of 0. (The "force unknown acl user" 
option is supposed to fix this, but it seems to be ignored according to 
testparm -x   - or am I doing something wrong?)

I could try copying them over and then seting the ACLs either through 
the Security dialog or with setfacl, but given that they're not all 
predictable (any random subfile could have rather different ACLs to its 
parent dir), and also given the sheer number involved, it would take, 
um, a while :(

This is Samba 2.2.7a on Debian unstable (can be reverted to stable if 
need be), and a fairly standard W2k server on domain-level security.

Any ideas for an [easier] way to do this?

TIA
Andrew
