I have a requirement for doing Incremental backup of MySQL database. For which I'm writing a shell script using the concept of binary logs.

Now, the scenario is such that a full-backup will happen every alternate day and Incremental backup should be done in between. Suppose full-backup happens on Monday and Wednesday, incremental backup should happen on Tuesday. For point in time recovery, I'm using mysqlbinlog --starttime --stoptime binary-logs > backup.sql In the shell script I need to use starttime and log position of the previous full-backup to specify the log files in the statement, how can I retrieve this in a shell script and record the changes done during that time. Is there anyway I can do this, please help me in this regard.

I honestly can't recommend it enough to just learn xtrabackup vs writing it on your own – kormoc Feb 15 '13 at 6:42
