It is a painful experience for all us administrators to truncate logs regularly. I just created a job to execute

sp_msforeachdb "use ?; backup log ? with truncate_only ; dbcc shrinkfile(2,5)"

on all the servers at frequent intervals. It has saved me a lot of time. hope it helps you too.

n.b: I assume that file id 2 is the log.(change it as per your installations)


thanks
