duplicate backup log resore

  • I have full backup job on 5.10 and log backup at every 15 minutes

    If I restore the full backup from 5.10 and the log backups performed after 5.15 there is any possibility to miss or duplicate any transaction?

  • No.

    No.

    not even if I restore same log twice?

  • SQL won't let you restore the same log backup twice.

    There is absolutely no chance whatsoever of ever being able to miss transactions in the middle or restore transactions twice when restoring full, diff and log backup sequence.
