This is a command-line option for the
mariabackup commands (arg: Required).
This option specifies the name of the backup series stored in the PERCONA_SCHEMA.xtrabackup_history history record to base an incremental backup on. MariaDB Backup will search the history table looking for the most recent (highest innodb_to_lsn), successful backup in the series and take the to_lsn value to use as the starting lsn for the incremental backup. This will be mutually exclusive with --incremental-history-uuid, --incremental-basedir and --incremental-lsn. If no valid lsn can be found (no series by that name, no successful backups by that name) MariaDB Backup will return with an error. It is used with the --incremental option.
