Do I need to backup log if log shipping is implemented in that database ?

  • Hi,

    Do I need to backup log if log shipping is implemented in that database ?

    Will the log backup taken by log shipping truncate the log file so that it won't keep on growing ?

    Or do I need to truncate it separately ?

    Thanks in advance.

  • you don't need any other log backups than the log backup job created by logshipping. Indeed, if you take other log backups it will break logshipping.

    The log backup taken by logshipping is no different than any other log backup

    why do you want to take Tlog backup when it is updated in other server through log shipping.

    Even if you think that log backup will not break log shipping chain.

    Experts i need your advice on below,

    if take a TLOG backup and keep it on the log shipping share drive will the log shipping happens without break? or will it take only the backup created by logshipping job?

    It WILL BREAK the log shipping chain right ?

    The moment you take TLOG backup it will break log shipping. Once the log shipping is broken, it shouldn't work with manually taken log backup apparently, if I understood correctly 🙂 .

    San, it will break the chain, but my question is why do need to back up the log if you have the log restored on other server?

    Thanks San, i too have the same idea but will sql accept if i keep the back on the location when it will take it and restore on other server hope anybody would have tried and tested it.

  • even if you back the log up to the same location as the log shipping backups it will still break log shipping as it will not be reflected in the log shipping tables.
