Can a MariaDB server be backed up with mariabackup?
A MariaDB Server version can often be backed up with most other Mariabackup releases in the same release series. For example, MariaDB 10.2.21 and MariaDB 10.2.22 are both in the MariaDB 10.2 release series, so MariaDB Server from MariaDB 10.2.21 could be backed up by Mariabackup from MariaDB 10.2.22, or vice versa.
Is there support for–stream = tar in MariaDB?
Support for –stream=tar was removed from Mariabackup in MariaDB 10.1.24 . The xbstream utility has been renamed to mbstream. However, to select this output format when creating a backup, Mariabackup’s –stream option still expects the xbstream value.
What happens when mariabackup restores a database?
When Mariabackup restores a database, it preserves the file and directory privileges of the backup. However, it writes the files to disk as the user and group restoring the database.
Why do I get an error when running mariabackup?
I want to run mariabackup from the host to create a physical backup of the data directory (which is /mnt/data as far as the host is concerned and /var/lib/mysql/ from the container’s perspective). I get an error, however, running mariabackup that says it cannot find the data directory:
Is there a link between Maria backup and innobackupex?
Percona XtraBackup’s libgcrypt-based encryption of backups is not supported by Mariabackup. There is no symbolic link from mariabackup to innobackupex, as there is for xtrabackup. Instead, mariabackup has the –innobackupex command-line option to enable innobackupex-compatible options.
Why is mariabackup designed to ignore unknown options?
If mariabackup raised an error or warning when it encountered an unknown option, then this process would generate a large amount of log messages under normal use. Therefore, mariabackup is designed to silently ignore the unknown options instead. See MDEV-18215 about that.
What’s the difference between Percona xtrabackup and Maria backup?
Percona XtraBackup copies its InnoDB redo log files to the file xtrabackup_logfile, while Mariabackup uses the file ib_logfile0 . Percona XtraBackup’s libgcrypt-based encryption of backups is not supported by Mariabackup.
