When you Mount an Offline Database you will be given the option to execute a NORMAL or FORENSIC Mount as shown below.
MOUNT - NORMAL
The default/normal MOUNT of a database runs several checks against the database to ensure consistency and IF log rollup is needed it will do so before mounting the database. Best way to think about the normal mount is that it performs the same checks an Exchange server would during its mounting process.
MOUNT - FORENSIC
The FORENSIC Mount process is used as an alternative to bypass a lengthy database repair action or the need for log rollup and is invaluable when;
- An offline database is damaged
- OR is in a dirty state requiring log rollup and all logs are not available
- OR if you have all the required logs but want to mount the database without committing the logs to avoid updating the database. For example this could be helpful if you have a database backup prior to deletions and changes that were made and want to see the contents of the DB without committing those changes contained in the logs to the database.
NOTE: Without the FORENSIC mount option if you encountered the above scenarios you would need to execute a full database repair action which can be a very lengthy process.
NOTE 2: The Forensic Mount only allows DigiScope to bypass the normal mount process, it DOES NOT modify the database in any way and therefore you cannot expect a DB that mounted Forensically in DigiScope to mount within a live Exchange Server.
