Unable to Backup Files with Error 800700B7

mgillespie · External Since: Feb 20, 2007 Posts: 1

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?

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.
