With incremental backups, this applies the deltas to the base backup.This is only valid in innobackupex mode, which can be enabled with the --innobackupex option.Before you can restore the data to MariaDB, you first need to prepare the backup.If you try to restore the database without first preparing the data, InnoDB rejects the new data as corrupt.
Running Mariabackup with the --prepare command readies the data so you can restore it to MariaDB Server. Backing Up To Debug Only Private Cache Update The BaseWhen working with incremental backups, you need to use the --prepare command and the --incremental-dir option to update the base backup with the deltas from an incremental backup. The backups are written to the target directory, as set by the --target-dir option. Backing Up To Debug Only Private Cache Full Backup CreatesA full backup creates a snapshot of the database in the target directory. ![]() ![]() When disabled with OFF, Mariabackup runs without attempting to retrieve binary log information. You may find this useful when you need to copy data without metadata like the binlog or replication coordinates. See the description of the xtrabackupbinlogposinnodb file for more information. If you attempt to run Mariabackup with this option, then it causes the utility to exit with an error. Without this option, Mariabackup keeps files open in order to manage DDL operations. When working with particularly large tablespaces, closing the file can make the backup more manageable. You may find this useful when backing up particularly large databases. However, currently, Mariabackup only supports the QuickLZ algorithm, which is the default value. It can also use multiple threads for parallel data compression during this process. Using this option, you can set the chunk size each thread uses during compression. Using this option, you can define the number of threads you want to use for this operation. You may find this useful in speeding up the compression of particularly large databases. You must stop the MariaDB Server before running this command. If you want to overwrite the data directory with the backup, use the --force-non-empty-directories option. In the case of full backups, this makes the files point-in-time consistent.
