These options specify various parameters related to the layout
of the backup directory. Several of these option values can be
derived automatically from the corresponding configuration
option without the backup prefix, thus the
--backup-dir option is the only one from this
group that you typically specify.
These options are used only with the following operations:
Backup creation operations:
backup,
backup-and-apply-log,
backup-to-image.
Restore operations: copy-back.
When a database connection is available during a backup, the parameters describing the source repository are ignored, overridden by the corresponding values retrieved from the database connection.
The following parameters describe the layout of files in the backup directory:
--backup-dir=PATH
--backup_innodb_data_file_path=VALUE
--backup_innodb_data_home_dir=PATH
--backup_innodb_log_group_home_dir=PATH
--backup_innodb_log_files_in_group=N
--backup_innodb_log_file_size=SIZE
--backup-dir=PATH
The directory under which to store the backup data. This is
a crucial parameter required for most kinds of backup
operations. It cannot be a subdirectory of the directory
specified by --datadir. An
additional level of subdirectory is created when the
--with-timestamp option is also specified.
--with-timestamp
Creates a subdirectory underneath the backup directory, with a name formed from the timestamp of the backup operation. Useful to maintain a single backup directory containing many backup snapshots.
Default: no timestamped subdirectory is created. To reuse
the same backup directory for a new backup, either remove
the previous backup files manually or specify the
--force option to overwrite
them.
