Basic difference between log shipping and mirroring

  • Hi

    I have some basic doubts between mirroring and log shipping .I know there is net but i didn`t proper result.In log shipping one have transactional backups occurring and then those backups files are shipped to secondary which are then restored.

    how is this carried out in mirroring , i mean where are this log files and how are they shipped

    Automatically. In mirroring the log records are sent across continually.

    but where are this log files kept

    I mean in logshipping there is folder where log files backups are stored but i donot see in any folder in which mirror log files are stored.

    Second how this log are sent i mean using sql agent or through any other way

    Where ever you choose to put the log backups that you take. Mirroring doesn't use log backups, so where they go is irrelevant. I imagine you'll put them with the rest of your backups

    Second how this log are sent i mean using sql agent or through any other way

    They're sent automatically across the mirroring end points that you set up when you configured mirroring.

    May I suggest google and look for a good article on the basics of mirroring?
