Thus, an individual database in Microsoft Exchange is only a dependent part of a
storage group, and backing it up separately becomes pointless, because it does not
guarantee a data integrity after restoring.
5.1.6 Circular Logging
The Microsoft Windows 2000 Active Directory service and the Microsoft Windows
Server 2003 Active Directory service use the circular logging feature to maintain
transactions in the database file (Ntds.dit). The log files are maintained until the data
that they contain is written to the database file. The circular logging feature uses these
log files to recover transactions if the database file is shut down in an inconsistent
state. For example, a power failure or a Stop error can cause a transaction failure. In
Windows 2000 and in Windows Server 2003, there is currently no way to disable the
circular logging feature.
5.1.7 Disaster Recovery Plan
With Acronis Recovery for MS Exchange you can create a Disaster Recovery Plan. This
plan provides all the necessary information about the Microsoft Exchange server in the
form of step-by-step instructions for restoring the entire server in case of failure, a
disaster, or data corruption.
With the Disaster Recovery Plan any person, even non-DBAs, will be able to restore the
system in the shortest possible time. Such a plan also helps to reduce unexpected
issues during the recovery of the Exchange server.
It is recommended that you update and test the disaster recovery plan from time to
time. Doing so will ensure that the company’s staff is prepared, acts efficiently, and
feels practiced in the process of recovering lost or corrupted data.
See Chapter 6 “Disaster Recovery Plan” to learn how Acronis Recovery for MS
Exchange can help you generate the disaster recovery plan.
