I have a db that I am trying to optimize the index rebuild process for. Because it is using up a lot of log space, I have switched the recovery model to bulk_logged mode, performed the index rebuild process and then switched the recovery model to full. The log space usage was very minimal which is great and solves the problem of log space.
But I noticed that the immediate size of T-Log backup file was still big. It was still backing up significant number of pages in the log even though the index rebuild was performed in bulk_logged recovery model. I thought it would minimally log the operation, but why is my T-Log backup file size still big after this process?
Thanks
