Full Recovery, no tlog growth

  • John Rowan (6/19/2008)


    Jeff, Do you have documentation to support that SQL Server behaves that way? I've never heard this before. Are you saying that if you create a new DB and set it to FULL recovery mode, that SQL Server will not 'act' as if it is in FULL mode until you take a backup? Again, I would like to see the resource where you learned this.

    Unfortunately, I do not have a documented resource. I learned this last week at TechEd during a session with Paul Randall and Kimberly Tripp. I don't recall how the question came up, but Kimberly outlined this and it stuck (actually, surprised me and I've been meaning to test this myself).

  • From my earlier post:"Tlog is doing nothing as far as I can see -- apparently that's because there is no full backup and thus no possibility of tlog backups. The tlog file is 6GB containing only 64mb of data. "

    It is set to a max size of 2 terrabytes with autogrowth on, but with only 64mb of 'active' data within a 6GB file it won't be growing anytime soon. I like to use the analogy of a five gallon gas can holding one gallon of gas to visualize sql server files.

    Is that why you're not supposed to smoke in the server room?!? I always wondered! :hehe:

    Thanks for the reply Jeff. It's always good to learn something that is undocumented. I was just curious as to where you got that from. Again, thanks.
