Legato LOB with regular LOB

  • Will Legato's backup sequence be affected by regular native Transaction Log backup?

    After taking a Full backup from Legato, and subsequent TK backups from Legato, if a DBA just makes an ad-hoc TL backup, will legato recognize it, or will it's sequence be broken?

    Dan.

  • Legato won't 'have' it - it'll just be wherever you backed it up to, not in Legato's store. So yes, the sequence will be broken as far as your Legato setup is concerned

  • But when you have to do a point in time recovery, if I move the TL backup that was done to the Legato's store, will it recognize the sequence, then, if you do according to the timestamp?

    Good question. Unfortunately it is a good question that exceeds my knowledge of the product I'm afraid.

    Put it this way though - it's not something I'd try on a production system. I'm a bit baffled as to why you'd want to take an out of sequence TL backup outwith your scheduled Legato backups tbh. What are you going to do with it?

  • I use EMC Networker as following:

    - Take full and differential backups with Legato to VTL

    - Take transaction log backups to disk with SQL Server utilities

    - Transfer transaction log backups from disk to VTL with Networker

    If point-in-time recovery is needed I restore from Networker with no recovery option and then I apply transaction logs from SQL Server.

    The product works fine with SQL Server 2000. In SQL Server 2005 I can't take differential backups for databases in full recovery model. This is a Networker's bug that is fixed in release 7.6 if I remember well.
