The backup operations are the most frequently performed tasks by
MySQL Enterprise Backup. Various kinds of backups can be
performed by adding different options, like using
--compress
or
--incremental
for compressed or
incremental backups. Here is the syntax for the
mysqlbackup commands for performing a backup
operation:
Press CTRL+C to copymysqlbackup [STD-OPTIONS] [CONNECTION-OPTIONS] [SERVER-REPOSITORY-OPTIONS] [BACKUP-REPOSITORY-OPTIONS] [METADATA-OPTIONS] [COMPRESSION-OPTIONS] [SPECIAL-BACKUP-TYPES-OPTIONS] [INCREMENTAL-BACKUP-OPTIONS] [PARTIAL-BACKUP-RESTORE-OPTIONS] [SINGLE-FILE-BACKUP-OPTIONS] [PERFORMANCE-SCALABILITY-CAPACITY-OPTIONS] [MESSAGE-LOGGING-OPTIONS] [PROGRESS-REPORT-OPTIONS] [ENCRYPTION-OPTIONS] [CLOUD-STORAGE-OPTIONS] [ENCRYPTED-INNODB-OPTIONS] backup-to-image mysqlbackup [STD-OPTIONS] [CONNECTION-OPTIONS] [SERVER-REPOSITORY-OPTIONS] [BACKUP-REPOSITORY-OPTIONS] [METADATA-OPTIONS] [COMPRESSION-OPTIONS] [SPECIAL-BACKUP-TYPES-OPTIONS] [INCREMENTAL-BACKUP-OPTIONS] [PARTIAL-BACKUP-RESTORE-OPTIONS] [PERFORMANCE-SCALABILITY-CAPACITY-OPTIONS] [MESSAGE-LOGGING-OPTIONS] [PROGRESS-REPORT-OPTIONS] [ENCRYPTED-INNODB-OPTIONS] backup | backup-and-apply-log
Produces a single-file backup holding the backup data. In most cases, single-file backups are preferred over directory backups, which are created using the
backup
command.The command requires the
--backup-image
option to specify the destination file. Can be used to stream the backup to a storage device or another system without ever storing the data on the database server. You can specify--backup-image=-
, representing standard output, allowing the output to be piped to another command. To avoid mixing normal informational messages with backup output, the--help
message, errors, alerts, and normal informational messages are always printed to standard error stream.The command also requires the use of the
--backup-dir
option to supply a temporary folder to save the backup metadata (including the mysqlbackup message log, the start and end LSN, and so on) and some temporary output.Backs up data to a directory. In most cases, single-file backups, which are created using the
backup-to-image
command, are preferred over directory backups.The command only performs the initial phase of a complete backup process. The second phase is performed later by running mysqlbackup again with the
apply-log
command, which makes the backup consistent.A combination of
backup
andapply-log
. It cannot be used for an incremental backup.
