Hi Kirk,
Usually the source of this oh-so-informative error message has to do with the 
widespread elevation of rights for the Agent user.  You might try logging into 
the destination db as the account and see if you can create a database.
Also-- if you are doing an in-place restore of a deleted site, it may not have 
the requisite "framework" to create the site into.  DocAve is picky about what 
you select (like the "." directory for example to restore-- it will allow you 
to pull out pieces that require destination site configuration to accept.  Did 
you select the whole platform backup to restore, or a (sub)site deeper in the 
hierarchy?  It is picky about that too.
Read the documentation carefully-- it will contain the caveats of how to do the 
restores, and the how-tos are very literal-- meaning the instructions show 
exactly how to do what they are demonstrating, but you shouldn't extrapolate 
processes from the examples.
Do you happen to know if there has been a Redbook put out on TDP for 
DB/SharePoint yet?

Good luck, HTH

Subject: [ADSM-L] Problems with DocAve SharePoint TDP Restore

Hi all,

We have some work currently underway to try and get the SharePoint TDP for TSM 
(aka DocAve) installed and working. We've downloaded and installed
v6.1.4 from Passport Advantage and have been able to configure and run 
successful backups.

However on testing the restore process, it seems that we're getting an error 
message - see below. This message has been generated when trying to carry out a 
site recovery, having deleted the site from within SharePoint
2010 in order to test the restore process.

09/26/2011 15:47:06 Type: (Site Collection) Path:
(http://mysite.example.ac.uk:100) , Status: (Successful)
09/26/2011 15:47:06 Type: (Site) Path: (http://mysite.example.ac.uk:100/.)
, Status: (Failed)
An error occurred while restoring a site. Url:..Object reference not set to an 
instance of an object.
Run Time:           00:00:26
Statistical result: <1 MB data, 1(0) site collections, 1(1) sites, 0(0) lists, 
0(0) folders, 0(0) items.

When the error message is produced, the correct domain appears in the error.

Has anyone else seen this error message before? I've seen a similar message 
when searching on adsm.org but not the same error message. There doesn't seem 
to be much other information available within the DocAve software itself, but 
it does look as though it is trying and failing to carry out an action on the 
database. It seems as though it is trying to connect to the database that has 
been deleted however I will have to ask the DBA to confirm that part tomorrow. 
The account has been given sa access on the database as a test and the error is 
still generated.

TSM version this is going to is v6.2.2 running on Linux however I don't think 
that is particularly relevant.

Any help gratefully received!

Cheers,
Steve
