[–parallel=NUMBER-OF-FORKS] BACKUP-DIR
–no-timestamp This option prevents creation of a time-stamped
subdirectory of the BACKUP-ROOT-DIR given on the command
line. When it is specified, the backup is done in
BACKUP-ROOT-DIR instead. //是否生成時間的文件
–kill-long-queries-timeout=#
This option specifies the number of seconds innobackupex
waits between starting FLUSH TABLES WITH READ LOCK and
killing those queries that block it. Default is 0
seconds, which means innobackupex will not attempt to
kill any queries. //殺死長時間的查詢
–rebuild-indexes This option only has effect when used together with the
–apply-log option and is passed directly to xtrabackup.
When used, makes xtrabackup rebuild all secondary indexes
after applying the log. This option is normally used to
prepare compact backups. See the XtraBackup manual for
more information. //開並行
–throttle=# This option specifies a number of I/O operations (pairs
of read+write) per second. It accepts an integer
argument. It is passed directly to xtrabackup’s
–throttle option. //限流
–incremental-basedir=name
This option specifies the directory containing the full
backup that is the base dataset for the incremental
backup. The option accepts a string argument. It is used
with the --incremental option. //增量備份的基礎 全備的位置
–incremental-dir=name
This option specifies the directory where the incremental
backup will be combined with the full backup to make a
new full backup. The option accepts a string argument.
It is used with the --incremental option. //增量備份到什麼位置
