About logs

Microsoft Exchange employs "write-ahead" logging to improve performance. As transactions occur, they are appended to a transaction log. Transactions are committed to the database when resources permit. A checkpoint file (E0n.CHK) tracks the location of the last transaction in the log files that has been successfully committed to the database. Transaction logs can be used to roll forward a database to achieve a point-of-failure recovery.

Note:

Do not enable the circular logging option. If circular logging is enabled, you will not be able to roll forward a database to achieve a point-of-failure recovery. Microsoft does not recommend circular logging in production environments. Refer to the Microsoft Exchange Server documentation for further details.
