Vista - Unable to Backup Files with Error 800700B7

It's not a NAS device as such, but a dedicated Linux PC, so I load
whatever version of SAMBA I wish.

I have tried the latest 2.0.34, and it still does not work, and I am
pretty sure it's a Vista issue, rather than a SAMBA issue, as I should
be able to backup to any network server I wish, regardless of server
OS...

Seriosuly how tricky would it be, so that if the logon and password
credentials are blank, to not store the credentials. The point is, I
can access the network shares perfectly in explorer.

The latest Samba is 3.x.x:
http://us3.samba.org/samba/history/samba-3.0.24.html. Backup must be able to
not only read/write/delete files but also set ACLs on them. We must protect
the backup file, and to do this, the SAMBA version must support this. If
there are bugs or other issues in the SAMBA code that don't allow us to set
ACLs, then we can't use that share as a target.

Give the latest version a try and see if that helps.

On your Linux server, you need to create an account that is not root and
allow it full access (meaning read, write and most important change ACLs,
sometimes called all access) on the share and on the files.

Unfortunately I don't have instructions for doing this. NAS boxes usually
have a web UI that you can use.

When you can perform the following steps successfully from the command line,
then Backup should be able to use it as a target:

- net use with the account against the share
- create a file on the share and put some small data in it
- the owner of the file should be user used in net use
- change the ACL of the file using cacls.exe
- delete the file
- create a directory on the share
- the owner of the file should be user used in net use
- change the ACL of the directory using cacls.exe
- delete the directory

Backup does this programmatically to determine whether the account has the
necessary access.

Update re- my previous post. I checked the firmware specifications for the Linksys/Cisco NSLU2 firmware V2.3R63 which I am using. Apprently, it is using Samba 3.0.11.

I'm curious what NAS devices Microsoft actually tested, seeing as how Linksys/Cisco is probably one of the more common ones. Perhaps a listing of tested/supported NAS devices that Microsoft knows works would be educational.

I'm having this same problem; however I'm using a Maxtor 1TB Shared Storage
II NAS drive. It is at the latest firmware from Maxtor 3.1.26 and I cannot
see any indications as to whether it is SAMBA or not.

Has anyone successfully backed up to the Maxtor Shared Storage II drives?

Apparently there is *no* currently available official release version of Samba that corrects the underlying problem with Vista's backup mechanism.

You can read about the technical details of the underlying issue on the Samba mailing list here. Samba 3.0.22 (as included with the Linksys NSLU2 device) doesn't incorporate the correction. Neither does the current version of Samba (3.0.24). The pre-release version of the next release (3.0.25pre2, released March 21, 2007) apparently incorporates the change. But it would be mighty hard for any NSA device vendor to incorporate an unreleased version.

Perhaps Vista backup was never actually tested with any existing official versions of Samba before it shipped. Or perhaps it worked with some older version of Samba, or some "special" version that exists only on some particular NSA device or devices.

Same problem(s) with WD My Book World Edition...

I can see that the new version of Samba now has been released, so I've send a request for a firmware update til WD (Western Digital), in hope that they will upgrade to the new version of Samba.

Any experience with the new Samba version?

hello,
same issue here with my new LaCie Ethernet Disk mini - Home Edition

any news of this issue ?

Just found the answer! Use the username everyone and your admin password for your NAS device. Everything works after that... I'm using Vista x64 and a WD Mybookworld NAS.
