SYMPTOMS
During a full online backup and after the Exchange Server directory has been backed up, Windows NT backup stops, with the following error messages written to the event viewer when it begins to back up the information store.

Event ID: 15

Source: EDB

Description: MSExchangeIS ((190)) The database engine has stopped the backup with error -1811.

Event ID: 105

Source: ESE97

Type: Error

Category: Logging/Recovery

Description: MSExchangeIS ((202) ) The database engine has stopped the backup with error -1811.



WORKAROUND
Error -1811 is JET_errFileNotFound. The error above signals that a transaction log file is either missing or corrupt. Perform the following steps to work around this problem:


 * 1) Stop the Information Store service.
 * 2) Remove all the .LOG files from the \Exchsrvr\Mdbdata directory, and place them in a temporary directory.
 * 3) Find the Edb.chk file (located in the \Exchsrvr\Mdbdata directory on one of the drives), and place it in the temporary directory.
 * 4) Start the Information Store service.
 * 5) Start the full online backup of the Exchange Server again.

Result: The full online backup should complete without error.
