 #Enabling continuous mirroring.
 
-You can enable continuous mirroring by editing a few files.
-One way to make sure the mirroring works continuously is to use the 'lockf' utility.
-This is one way to do it.
-
-    # mkdir /root/adm && cd /root/adm
-    # touch .lockfile
-
-Now make two scripts 'hms' and 'hmc' with the following contents inside /root/adm
-
-    # cat hms
-    hammer mirror-stream /Backup1/test /Backup2/test &
-
-    # cat hmc
-    hammer synctid /Backup1/test
-    hammer mirror-copy /Backup1/test /Backup2/test

+The hammer mirror-stream will automatically restart if the connection is lost so you only need to start it up once at boot.You can do this with an @reboot entry in the crontab.
