backups getting code 71 "none of the files in the files list exist"

Just W2008 or W2008 R2?

Windows 2008 R2 is only supported as from NBU 6.5.5.

There have been many issues with System State and/or Shadow Copy Components backups for W2008 that got fixed in NBU 7.1.0.2 and 7.1.0.3. So... you REALLY need to upgrade!

Please upgrade client to 7.5 followed by latest patch (7.5.0.6 or 7.5.0.7) and let us know if problem persists.

After upgrade, create all of these log folders on the client:
bpcd bpbkar bpfis.

We will need logs to troubleshoot if errors are seen after upgrade.

You can always use newer NBU version to restore previous version backups.

I have even seen 5.x backups being restored with NBU 7.x.

Best to upgrade client and see if backup works.

If not, you will at least be at a supported NBU version that can be logged with Symantec Support.

If this is what it says then the answer is pretty easy - I assume your policy is something like:

C:\

System State

If so then simply change the "System State" to "Shadow Copy Components" and it should then work

The policy does explain it - i have seen this many times with 6.5 clients - System State for XP and WIndows 2000 - Shadow Copy Components for everything else - shouldnt be the case but it is

Hope it goes ok now
