Impact of shrinking ldf file after restoring full backup What is the use of data in .ldf(log) file after restoring a full backup. I am planning to shrink the log files after restoring the full backup in my dev server. 

Is there any side effect for this ?

No, not really. The worst thing that could happen is the log file grows again, given this is a dev server that's not a problem. Worst case is the log takes up all available space and your db goes into read-only... which is easily rectifiable and downtime is fine as it's a dev server.

Shrink away.
