Circular logging log file is of 1 MB in Size. When the size
of the Transaction log is full then another log file is
created and so on.

By default circular logging is enabled to write the logs
and when you need the backup it needs to be disabled.

Current Tranction log exceed more then 1 mb ,it will create
another log file.it will use more storage.if you configure
circular logging it will replace the old tranction
log.remember circular logging don't enable in production
enr,otherwise you can recover data only from the last backup

Answer / oded

You can configure Exchange to save disk space by enabling
circular logging. Circular logging allows Exchange to
overwrite transaction log files after the data that the log
files contain is committed to the database. However, if
circular logging is enabled, you can recover data only up
until the last full backup. For example, you can enable
circular logging when using Exchange native data protection,
in which you don't make backups. To prevent log buildup, you
need to enable circular logging.

Answer / jacintha

Circular logging keeps all restart data in a ring of log
files. Logging fills the first file in the ring, then moves
on to the next, and so on, until all the files are full. It
then goes back to the first file in the ring and starts
again. This continues as long as the product is in use, and
has the advantage that you never run out of log files.
