Abstract
Enabling point-in-time recovery for databases which change transaction log recovery models is described. If a database is associated with a recovery model that creates independent backups of the database's transaction log, a system identifies most recent backup information and a current transaction log sequence number. If the most recent backup information includes a transaction log sequence number and the current transaction log sequence number is a reset value, the system creates a full backup of the database, without first creating any independent backup of the transaction log. The system creates an independent backup of the transaction log when the independent backup of the transaction log is scheduled next, subsequent to creating the full backup of the database.
