As database backups can grow substantially in size, compressing backups helps to preserve disk space. While the mariabackup utility offers no compression by itself, we can stream the backup into a compression tool to create an archive [1]. The xtrabackup_checkpoints file, which contains metadata on a backup, gets stored alongside the archive, allowing to create incremental backups from non-compressed backups and vice-versa [2]. One thing to note, is that compressed backups cannot be prepared in advance, this step must be manually carried out by the user. Backup compression is disabled by default and different compressors can be chosen (zstd, xz, ...), with gzip being the default.
