Exchange Server crash is a common concern for all administrators which can happen due to logical and system errors. In case of eventualities, they wish to fix the problem as early as possible. The Exchange Server crash relates to sudden server shutdown or server down for a long time and for its recovery and maintenance, administrators have native recovery methods based on the availability of the database backup. Here, we will discuss some recovery options available for them.

Exchange recovery options – Soft Recovery & Hard Recovery

Exchange provides two recovery options for administrators– Eseutil Soft Recovery and Eseutil Hard Recovery. First, let us have a general introduction to the two recovery options:

  • Soft Recovery: In this, transaction log files are replayed when the database is mounted again after an abrupt Exchange stoppage, or they are replayed against an offline copy of the database.
  • Hard Recovery: In this, transaction logs are replayed once the database is restored from online backup.

Note: For both types of recovery, database backup should be available online, and the log file must not be in a corrupt state.

How to perform Soft Recovery?

To run Soft Recovery, mount any database in the storage group as all databases in a storage group share the same stream of log files.

The syntax to be used for Eseutil.exe soft recovery is given below:

ESEUTIL /r enn /L [path to log files] /s [path to checkpoint file] /d [path to database file] /i

Note: It is not possible:

  1. To replay log files to a different database.
  2. To replay log files if any database file has been removed from the storage group.
  3. To replay log files if checkpoint file points to the wrong log.
  4. To replay log files if you don’t have all log files available.
  5. To replay log files if database files have been moved to a different file path location.

How to perform Hard Recovery?

To perform Hard Recovery, you must have restored the database from online backup. The syntax to be used for Eseutil.exe hared recovery is given below:

ESEUTIL /cc [path to the restore.env folder]

Note: The Restore.env file should be present in the folder for hard recovery.

As Eseutil is difficult to run, it is advised to use a third-party professional software which performs a full recovery of data from lost or corrupted files. Kernel for Exchange Server Recovery software proficiently recovers EDB data, whether corrupted, lost or deleted, and saves it to the specified location. Also, there are no chances of any error in the recovery. Other than recovery, the EDB to PST tool migrates EDB to different destinations including Exchange Server and Office 365.
