I'm trying to back up from Vista Ultimate to a share on a networked
Linksys NSLU2 I named NAS1. The share is 'backup'. Backup can browse
to the folder at which point I get a userid/pw prompt. After
completing login to NAS1, Vista backup consistently fails because
"Cannot create a file when that file already exists. (0x80070087)".

When I look in the share directory, there's a new subdirectory with
long hexadecimal name. It wasn't there before I started backup, so
backup created it then wants to try to created it again?

Any suggestions for resolution?

TIA

This is indeed a reason why backing up to mapped drives isn't supported
with Windows Vista.

According to Microsoft, to use a NAS device as a backup target, you
need to create the share with "Full Control" privileges for the user whose
credentials they want to connect with.

If this doesn't work, contact your NAS manufacturer to ask them for
upgraded firmware based on 3.x version of Samba.

The account in question is adminstrator on the NAS. Why would that not
work?

If it matters, I didn't use a mapped drive letter. I used UNC,
\\NAS1\BACKUP.

Some other users have reported problems that turned out to be Samba bugs. In
terms of troubleshooting you could try to use a subfolder under the share
and see if that works. If it doesn't, sometimes a firmware update is what is
needed to have this device behave as expected. The more recent Samba
versions (3.0.2.x) are more stable.

FYI. I tried adding the subfolder under the share and it didn't work. Why on earth would Vista have been designed not to support backing up to NAS? What Rocket Scientist thought that was a good idea?
