Exchange Server Database Level Backup & Active Directory
Remote Backup uses Windows Volume Shadow Copy Service (VSS) to backup Exchange 2003, 2007 and 2010, and Active Directory 2008. A snapshot of the Exchange and Active Directory files are taken to ensure the consistency of the backup data. Once the snapshot is complete, Exchange database and log files are checked for integrity. If the integrity check fails, an exception is written to the backup log file and Remote Backup proceeds to the next item.
Full AND Differential Backup Available:
- Exchange 2003
- Exchange 2007
- Exchange 2010
Full Backup Only:
- Active Directory 2008
The first backup is always a full backup (irrespective of the backup type selected), which will backup the database and the log files. When the full backup finishes successfully, the transaction log files are flushed.
Successive backups are differential (irrespective of the backup type selected), and back up only the transaction log files. After every differential backup a check is performed to confirm that the Exchange server can be rebuilt using the last differential and the dependent full backup. If this check fails, a full backup is forced.
