FULL Recovery mode changed to BULK LOGGED does that break the t-log chain?

    Should be a quick question I hope. I've forgotten the answer. If you change a 2005 database from FULL to BULK-LOGGED recovery mode when you do your Index rebuilding and then change it back to FULL, doesn't that break the T-Log backup chain?

    Thanks,

    No - changing from FULL to BULK-LOGGED and back again does not break the log chain. Changing to/from SIMPLE breaks the log chain.

    See the article I link to in my signature for more information on how to manage your transaction logs.

    If I change from full to bulk logged on replicated database (published), rebuild the indexes and change back to full.

    Will it impact replication? Should I stop any of the agents before it?

    I need to do it because of tran. log disk becomes full. BTW I am using SQL 2000 SP3.

    Replication does not depend in any way on recovery model.

    I will be loading several thousand records. If I temporarily change my recovery model from FULL to BULK LOGGED, will I lose the ability to recover to a point in time?

    This link seems to indicate that.

    Yes, but just within the log backup interval that contains the bulk operations.

    p.s. Please post new questions in a new thread in future. Thanks
