We have 3 main databases. Data file on one drive (10.5Gb, 15Gb and 13Gb in size). The logs are on separate drives. Each db is backed up full each morning and the logs are backed up hourly. It is only 3PM and the logs are now 17Gb, 6.7Gb and 6.1Gb). How could 1 database that is only 10.5 Gb in size have a log that is 17Gb in only 6 hours since it was last backed up. I noticed this yesterday and actually shrunk each log to see what they would be today.
My backups of the db and logs are identical as they were on SQL 2005 but now on this server it's out of hand. They never, every grew like this. The applications have not changed.
I ran DBCC SQLPERF(Logspace) and only 0.3 is being used of the 17Gb. It is showing that the last backup was at 3PM EST.
Our backups are also getting all of this data added to it. Starts out under 10Gb for the first one and now sits at 26Gb. How could a 10Gb database have a 26Gb backup in the same day?
