HI, we talked about this some month ago.. does anybody know if it will be improved soon?
So mainly ist a ceph problem. Or also should we communicate with the qemu devs? making bigger backups now takes way to much time. Making a backup from a node wich has about 5tb will take about 36 hours.... :-( -----Ursprüngliche Nachricht----- Von: pve-devel [mailto:[email protected]] Im Auftrag von Dmitry Petuhov Gesendet: Freitag, 17.
