Prepare an individual partitions backup¶
For preparing partial backups, the procedure is analogous to restoring individual tables. Apply the logs and use xtrabackup --export:
$ xtrabackup --apply-log --export /mnt/backup/2012-08-28_10-29-09
You may see warnings in the output about tables that do not exist. This happens because InnoDB-based engines stores its data dictionary inside the tablespace files. xtrabackup removes the missing tables (those that haven’t been selected in the partial backup) from the data dictionary in order to avoid future warnings or errors.
The next step is to restore the backup.
