Recovery from encrypted tapes?


This will be on a Linux DR test server, not the production sever, but running same release.

Can you restore the database without the keys, as a test? If so, is it necessary to have first backed it up on the production server without the keys?

If you are able to restore without the keys then I would expect that you should be able to restore data from a non-encrypted tape since that wouldn't require a key. However, what happens if you then attempt to restore from an encrypted tape? Will it fail immediately? Or will it succeed, but the data will be unintelligible? Either way, it seems a fair test to ensure that the data really is being encrypted on the production server.

Also, does the password for the database instance user have to be the same as the server where the database backup was created? If not, then all you will need is the password used to protect the master key? That it?

From help set dbrecovery:
Specifies that database backups include a copy of the
master encryption key for the server that is used to
encrypt node passwords, administrator passwords, and
storage pool data. The master encryption key is stored
in the dsmkeydb files. If you lose the dsmkeydb files,
nodes and administrators are unable to authenticate with
the server because the server is unable to read the
passwords that are encrypted by using the master
encryption key. In addition, any data that is stored in
an encrypted storage pool cannot be retrieved without
the master encryption key. This parameter is optional.
The default value is Yes. You can specify one of the
following values:

Attention: If you specify PROTECTKEYS=NO, you
must manually back up the master encryption key
for the server and make the key available when
you implement disaster recovery. You cannot
recover from a disaster without the master
encryption key.
