A database log backup is a type of backup that captures all the transaction log records generated by a database since the last log backup. These logs record every change made to the database—such as inserts, updates, and deletes, allowing you to track and recover data changes over time.
And yes, i2Backup supports database log backup. By combining a full backup, optional differential backups, and a sequence of log backups, you can restore a database to a very specific moment (for example, right before a failure or data corruption occurred). Log backups are typically small and frequent, helping reduce data loss risk while also preventing the transaction log from growing indefinitely.
