MySQL Enterprise Backup Glossary
These terms are commonly used in information about the MySQL Enterprise Backup product.
A
.ARM file
Metadata for ARCHIVE tables. Contrast with .ARZ file. Files with this extension are always included in backups
produced by the mysqlbackup command of the MySQL Enterprise Backup product.
See Also .ARZ file.
.ARZ file
Data for ARCHIVE tables. Contrast with .ARM file. Files with this extension are always included in backups
produced by the mysqlbackup command of the MySQL Enterprise Backup product.
See Also .ARM file.
Antelope
The code name for the original InnoDB file format. It supports the redundant and compact row formats, but not
the newer dynamic and compressed row formats available in the Barracuda file format.
If your application could benefit from InnoDB table compression, or uses BLOBs or large text columns that could
benefit from the dynamic row format, you might switch some tables to Barracuda format. You select the file format
to use by setting the innodb_file_format option before creating the table.
See Also Barracuda, compression, file format.
apply
The operation that transforms a raw backup into a prepared backup by incorporating changes that occurred
while the backup was running, using data from the log.
See Also log, prepared backup, raw backup.
B
backup
The process of copying some or all table data and metadata from a MySQL instance, for safekeeping. Can also
refer to the set of copied files. This is a crucial task for DBAs. The reverse of this process is the restore operation.
With MySQL, physical backups are performed by the MySQL Enterprise Backup product, and logical
backups are performed by the mysqldump command. These techniques have different characteristics in terms of
size and representation of the backup data, and speed (especially speed of the restore operation).
Backups are further classified as hot, warm, or cold depending on how much they interfere with normal database
operation. (Hot backups have the least interference, cold backups the most.)
See Also cold backup, hot backup, logical backup, mysqldump, physical backup, warm backup.
backup directory
The directory under which the backup data and metadata are stored, permanently or temporarily. It is used in
most kinds of backup and restore operations, including single-file backups and restores. See the description of
the --backup-dir option on how the backup directory is used for different purposes and for different operations.
backup repository
Contrast with server repository.
See Also repository, server repository.
backup-my.cnf
A small configuration file generated by MySQL Enterprise Backup, containing a minimal set of configuration
parameters. This file records the settings that apply to this backup data. Subsequent operations, such as the
