Mirrored DB log file growth is High

    I have mirroring setup in SQL 2008r2 server, Everything working fine.

    But MirroredDB LDF file growth is very high. How restrict the LDF file growth.

    With,

    Bharath.

  • You don't. You should monitor your log on both principal and mirror, is agent that applies the log on the mirror working, and state of the mirroring session. Investigate the cause. What percentage of the log is active on the principal and mirror? Dbcc loginfo. Sys.databases.log_reuse_wait_desc. Is you network speed high enough to accomodate log generation rate?

  • One question - how often are you backing up your log?
