| Description |
|
The current Mariadb-backup --compress option as deprecated for quite a while now as the underlying quickpress library and qpress tool have been unmaintained for over a decade by now. We have to start supporting the other compression algorithms Zstandard (ZSTD) and lz4 like Percona XtraBackup 8.0.34-29 https://docs.percona.com/percona-xtrabackup/8.0/create-compressed-backup.html#version-updates |

mariadb-backup supports any compression,algorithm via pipe aka xbstream (also encryption, and combination of those) https://mariadb.com/kb/en/using-encryption-and-compression-tools-with-mariabackup/ compressing individual files was a bad idea from the very start. I do not think we have to repeat Percona's mistakes (their builtin encryption resulted into several CVE btw), and have everything builtin. Rather, build tools that can work well with other tools, Unix philosophy. |

I just "added support" to documentation https://mariadb.com/kb/en/using-encryption-and-compression-tools-with-mariabackup/#compressing-with-zstd |
