backup maria db with out shutdown db
what is the best way to backup a 3 server VM installation of Maria DB without being able to shutdown the database
Answer Answered by Harald Reindl in this comment.
depending on your virtualization you normally should have the option to freeze filesystems and make snapshot-backups from the whole VM like VMware DataProtection including deduplication - use the capabilities virtualization offers
in any other case or additional i just setup a replication slave which can be stopped and the datadir rsynced at any point in time without taking the producvtion master down
after the salve is started again it syncs with the master
