Testing backups is always wise...

Dryrun won't be able to detect missing structural entries: that
requires a database. Even an internal list of DNs is not
enough, as the actual entries have to be available in order to
check things like schema and content rules.

To be a valid test you really have to import the data into a
server with configuration identical to the production server.
If that would take too long then a reasonable compromise might
be to import to a server set up to write data as fast as
possible. You could reasonably turn off all database-safety
functions to do that, or put the database on a ramdisk.
Even if you use hdb on the production servers you might
consider trying mdb for the backup tests.
