Hello SQL Masters,
Greetings!
I would just like to ask regarding Transaction log backup. While backing up the T-log, is there still incoming transaction to write on log?
Thank you and Best Regards,

Yes. There can be incoming transactions when a transaction log backup is in process.
The backup will include the transactions even if they are uncommitted with appropriate status information so that the restore process can rollback or roll forward the transactions.

Yes, additional writes can occur to the log after you start a log backup.
But the log backup itself will contain only logs records up to the time the log backup started.
Stated another way: new log records written after the log backup starts are not written to the log backup that is running at the time.
