4.1.7 Compression Options

For instructions about using these options, see Section 3.3.3, “Making a Compressed Backup”.

  • --compress

    Create backup in compressed format. For a regular backup, only the InnoDB data files are created in compressed format, using the .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 compress-level option.

  • --compress-level=LEVEL

    Specifies the level of compression. Value 0 disables compression. Value 1 is fastest compression, and value 9 is highest (and slowest) compression.

    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.

  • --uncompress

    When used with the apply-log operation, uncompresses the compressed backup before applying the InnoDB log.
