Good to know! 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.
Thanks for the help.
