Hi

I am reposting this just in case someone who would be able to assist me did
not see it first time around.

Thanks
Deon.

I am currently putting together a backup system for our MySQL server.  The
way I want to do this is to make use of mysqldump to perform the backup and
have the binary log (on a different disk to my databases) turned on so as to
be able to recover up until just before the point of failure.

My question in essence is this:  How do I control what is recovered from the
binary after performing a restore?  I am thinking as an example of the
scenario where just before a table is backed up, data is modified in that
table - thus adding the entry to the binary log - with the result that the
modification is already in my backup, as well as in the log.  I then, after
a failure, restore my backup, replay my log and the modification is
duplicated.

A second question which may answer my first is, the "--lock-tables" option
in mysqldump, does that lock all tables in the database which is currently
being backup up, or just the table which is currently being backed up?  With
regards to my question above, the first option would be advantageous, but
obviously it would not be helpful to have a database which takes an hour to
backup locked for that entire time???

Any thoughts will be appreaciated.

Thanks
Deon.
