Option Sets Variable
Set the storage engine recovery mode. The option value is any combination of the values

of DEFAULT, BACKUP, FORCE, or QUICK. If you specify multiple values, separate them by commas.
Specifying the option with no argument is the same as specifying DEFAULT, and specifying with an
explicit value of disables recovery (same as not giving the option). If recovery is enabled, each

closed properly. (The last option works only if you are running with external locking disabled.) If this
is the case,
mysqld
it.
The following options affect how the repair works.
Option Description
Recovery without backup, forcing, or quick checking.
DEFAULT
If the data file was changed during recovery, save a backup of the
BACKUP
tbl_name.MYD
Run recovery even if we would lose more than one row from the
FORCE
Do not check the rows in the table if there are not any delete blocks.
QUICK
Before the server automatically repairs a table, it writes a note about the repair to the error log. If you
want to be able to recover from most problems without user intervention, you should use the options
BACKUP,FORCE. This forces a repair of a table even if some rows would be deleted, but it keeps the
old data file as a backup so that you can later examine what happened.
