restoring reporting services

Can you restore reporting services from a  tape backup? How would you go about doing that

I am asking because I deleted encrypted content without backing up the key (I backed up the databases though and restored them. - I now cannot get into report manager.

You've not got issues as the installation ID in the database may not match the installation ID of the server SSRS is installed on.

To get over the encryption issue; You need to use the RSKeyMgmt utility to get this working:

This will also help reset the installation ID's in the database and the report server.

Typo....You've got issues as the...

that may be right.

so I guess I need to user rskeymgmt -r to remove the install id ..but what do I do to put it back?

Just a bit more background on my problem

In reporting manager I get the error:
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help

the log file says
w3wp!library!7!11/05/2008-08:43:50:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.InternalCatalogException: An internal error occurred on the report server. See the error log for more details., Incorrect security descriptor version

I don't see anything too interesting in the event logs.

When I use a new reportserver db all is ok (except lost all my data). Restoring the old one is the problem

Does this still sound like installion id problem?
Yes. As your installation related to that DB. I cant remember the option; but looking into the RSKeyMgmt should give you which option it is.

From my understanding reading the RSKeyMgmt doco the installationID is the encryption key. And to replace it you need  to have a backup of the encryption key so you can restore it to make the database work. Is that what you are thinking?

The reason why I ask is because.. I have heard of instances where people have deleted encrypted content (which includes the keys) and it has not stopped Report Manager from working.

you can't restore a reporting services database that is encrypted if you haven't backed up the key
