Recovering the IDB
Several recovery methods are available for recovering the Internal Database. Depending on the
identified level of corruption, your requirements, and the availability of the
IDB recovery file and the
original device and
transaction logs, the recovery procedure can differ.
The most convenient complete recovery
This recovery method guides you through restoring the IDB and replaying transaction logs. If
transaction logs are not available, you can still update the IDB by importing all media since the
last IDB backup.

recover the complete IDB, but for some reason you cannot perform the guided autorecovery
method. The recovery consists of restoring the IDB and updating the IDB.
