In our production database (Sql Server 2012) .ldf file is increasing rapidly. Yesterday we truncated the log file and made it to 1 MB in size but within 1 hr it became 35 GB in size.
Now we are running database in full recovery mode and performing regular transaction log backup at every 30 minutes time interval in order to slow down the log growth.
Please tell us what are the possible reasons for such rapid growth of .ldf files? And how we can resolve this issue?
