As a part of transactional records, transactional data is grouped with associated master data and reference data. Transactional data records a time and relevant reference data needed for a particular transaction record.
Every SQL Server transaction log is made of Virtual Log Files (VLFs). During the truncation process, only the Logical log is scanned. A Logical log is made of active VLFs. A Log Sequence Number (LSN) is used to uniquely identify every transaction in the online transaction log.hatâs why the online transaction log has some reserved space and is usually bigger than the SQL Server transaction log backup. Moreover, a transaction log backup contains only the transactions made after the last transaction log backup.
