Differentail Backup Did not Pick up Last Full Backup

  • Hi,

    Whilst preparing to move a DB between ISP's last night, I choose to preform a full backup in the morning , and then preform a differential backup in the evening due to the transfer time of the DB.

    Resulted in a failure, as the Diffential Backup did not pick up the lastest full backup , but the one beforehand.

    Any idea why

  • Could it have been a copy only full backup that you performed?

  • I thought about that , but as you cannot specify it from the GUI I dismissed it, but I rememered that I reran a scripted job and you are correct.

    Thanks
