SYMPTOMS
When you use Seagate Backup Exec version 7.0 to back up Exchange Server version 4.x, 5.0, or 5.5, the following error message may appear on the server that you are backing up:

Event ID: 156

Source: ESE97

Description:

MSExchangeDS ((210) ) Database C:\exchsrvr\DSADATA\dir.edb needs a full backup before incremental backup.

Event ID 156 may also be logged in the application log, with MSExchangeIS cited as the source.

On the server where you are performing the backup, you may receive the following error message:

Event ID: 57920

Description: An error occurred while preparing Microsoft Exchange Server \\servername\Microsoft Exchange directory to backup database Exchange DS database. Error code 0xc8000230. The database missed a previous full backup before the incremental backup.



CAUSE
This behavior can occur because, in order to perform a full backup, Backup Exec relies on the archive bit's being set. Occasionally, Backup Exec does not reset the archive bit and therefore cannot perform a full backup. This is a known behavior with Backup Exec 7.0 and earlier versions.



RESOLUTION
To resolve this behavior, contact the Backup Exec vendor, Veritas, to obtain a fix. The fix that resolves the behavior is BNT7I725.EXE.



WORKAROUND
To work around this behavior, use NTBackup.exe to perform a full backup.
