Re: [rdiff-backup-users] Winsdows 7/Vista ACLs not restored correctly?

[Dominic Raferd]

Sorry Leland, I have always explicitly excluded acls from my Windows backups. But in any case for ACLs rdiff-backup requires the pylibacl and pyxattr modules. My standard rdiff-backup installation (under Ubuntu 12.04) does not have pylibacl or pyxattr. You can check whether you have them in your Debian with:

pydoc modules|egrep -o "(pylibacl|pyxattr)"

Could this be your problem?

Hello Dominic,

Thank you for taking the time to reply.

As I said, I've tried quite a few combinations of things but figured my
initial post would be long enough without going through them all.  Also,
I figured the case I outlined was the simplest one (i.e. least number of
variables to worry about).  But since you ask ...

Leland, have you tried doing the backup from your Windows machine to a
Linux host and then restoring from there?

Since Linux is my OS of choice, this was actually the first thing I
tried.  My Linux boxes run Debian GNU/Linux.  I have one running
"squeeze/stable" and one running "wheezy/testing".  Only rdiff-backup
1.2.8 is available as an official Debian package though I also tried
removing the Debian package and building/installing 1.3.3 from source.
In each case the corresponding win32 native binary was installed on the
Windows side.  Also, on the Windows/client side I tried using both the
Cygwin OpenSSH and PuTTY to make the connection to the Linux box.

In all cases, as best I can remember, the result was the same as in the
simple case I outlined originally (i.e. no errors but restored
permissions/ACLs were wrong).

Or, if that is not possible, using the linux version of rdiff-backup
on your Windows machine through cygwin?

I assume you mean using the Cygwin version of rdiff-backup on the
Windows machine to backup and restore to/from the linux box?  I've tried
this too and the results are (mostly) worse.  For example, I removed the
win32 native rdiff-backup, installed Cygwin's version (1.2.8), and did
(in a Cygwin rxvt/bash window):

--------
prompt> rdiff-backup -v 5 /cygdrive/c/Users/Leland
address@hidden::tmp/Backup/Leland > ./Leland_backup.log 2>&1

prompt> rdiff-backup -v 5 -r now
address@hidden::tmp/Backup/Leland /cygdrive/c/Users/Leland.restore

./Leland_restore.log 2>&1

--------

After this, here are the permissions on C:\Users\Leland and C:\Users
\Leland.restored

C:\Users\Leland (the original source directory):
--------
SYSTEM: <not inherited>, Full Control, This folder, subfolders and files
Leland: <not inherited>, Full Control, This folder, subfolders and files
Administrators: <not inherited>, Full Control, This folder, subfolders 
  and files

and on the restored C:\Users\Leland.restored directory:
--------
lbest: <not inherited>, Special, This folder only
None: <not inherited>, Special, This folder only
Everyone: <not inherited>, Special, This folder, subfolders and files
SYSTEM: <not inherited>, Full Control, This folder, subfolders and files
Administrator: <not inherited>, Full Control, This folder, subfolders 
  and files
Users: <not inherited>, Read & Execute, This folder, subfolders and 
  files
CREATOR OWNER: <not inherited>, Special, subfolders and files only
CREATOR GROUP: <not inherited>, Special, subfolders and files only

The only _good_ thing is that it gets "<not inherited>" right.
Everything else is all bollixed up.  The original owner (Leland) has no
permissions at all!

BTW, I also tried this using the Cygwin rdiff-backup entirely locally on
the Windows machine with exactly the same results.  At least it's
consistent.

Is the format of the windows metadata and ACL files (stored in the
rdiff-backup-data directory) documented anywhere?  Then maybe I could at
least determine whether the permissions and ACLs were being stored
correctly in the backup.

I take it nobody else has had this problem?  If not, then it must be
something weird in my setup.  But I'm clueless what it could be.  Locale
maybe?  I dunno.

Thanks again for your time.

Cheers
Leland
