MySQL Enterprise Backup User's Guide (Version 8.4.1)
The general options are options of a general nature, or options that are not classified under any other specific option group:
The following general options also exist for the mysql command. Full descriptions for these options can be found in the MySQL reference manual, for example in Server Option, System Variable, and Status Variable Reference. These options must be specified ahead of any other mysqlbackup options, including the rest of the general options:
--print-defaults:
Print the program argument list and exit.
--no-defaults:
Don't read default options from any option file.
--defaults-file=:
Only read default options from the given file. It has to
be the first option to be specified, if used.
PATH
--defaults-extra-file=:
Read this file after the global files are read.
PATH
--defaults-group-suffix=:
Also read option groups with the usual names and a
suffix of strstr.
The following options are also common between
mysqlbackup and mysql,
and full descriptions for them can be found in the MySQL
reference manual, accessible through, e.g.,
Server Option, System Variable, and Status Variable Reference.
However, mysqlbackup does not accept any
short forms for these options as mysql
does (for example, you must use --help
instead of -h for
mysqlbackup):
More general options are available for mysqlbackup:
--debug=STRING:
Print additional debug information.
The option accepts one or more of the following arguments (multiple values should be separated by semicolons (;)) :
all: Print additional debug
information for all operations
sbt: Print additional debug
information for operations
using the System Backup to Tape (SBT)
interface
page_validation: Print debug
information for validation operations.
hole_punch: Print debug
information for transparent page compression for
backups.
tablespace_flags: Print flags
read from tablespaces.
io_file: Print debug information
for reading and writing files.
keyring_migration_tool: Print
debug information on keyring migration operations.
--force: (Deprecated and
ignored
): By default, some of the operations halt
rather than overwrite any user data or log files when
told to write to existing files.
--force allows the following:
For any restore operations, do NOT attempt to restore
data to a non-empty data directory using the
--force option; doing so
may cause data corruption and other unexpected
behaviors. Do not use the
--force option with a
copy-back or a
copy-back-and-apply-log
operation.
Overwriting of InnoDB data and log files during
the apply-log and
apply-incremental-backup
operations.
Replacing of an image file during an
backup-to-image or
backup-dir-to-image operation.
