Hinweise

In general, transaction log records are archived by making a backup of records of committed transactions. Space used for archived transaction log records is reclaimed by reuse or by shrinking the operating system file(s) maintaining the transaction log.

Wichtig
The Truncate method allows reuse of the space allocated to the operating system file(s) maintaining a transaction log. Log truncation is part of normal transaction log backup. If log backup is part of a database backup strategy, the Truncatemethod should never be called.
