For instructions about using these options, see Section 3.3.3, “Making a Compressed Backup”.
Create backup in compressed format. For a regular backup,
only the InnoDB data files are created in compressed format,
.ibz extension. For a
single-image backup, again only the InnoDB data files are
compressed inside the backup image.
Default: compression is disabled. Default compression level
is 1 when compression is enabled. You can change the amount
of compression with the
Default: 1 (lowest and fastest compression). Explicitly
specifying a non-zero value through configuration file or
command line automatically enables the
--compress option as well.
When used with the
operation, uncompresses the compressed backup before
applying the InnoDB log.
