I have 2 servers et up in a log ship scenario. Every hour, I backup the tran log and restore it on the other server. The log backup file normally ranges from 100 K to 200 Meg. On Sunday AM, the log backup file goes to 12 Gig. The database is 19 Gig normally and the log file is about 4 Gig normally. The only other thing I see on Sunday mornings is the Optimization and Integrity check job. Any ideas on why somethign like this is happening?
