In the past I had done offline backups, but I had eventually figured that xfsdump + mysqldump might get me what I want without rebooting. Given that I don't have any LVM to provide snapshots, the best bet may be to have an offline backup for guaranteed, bare-metal restores. And xfsdump/mysqldump for more-handy online backups / restores.
