Why do backups with ceph make so high iops?
I get around 600 iops for 40mb/sec which is by the way very slow for a backup.
When I make a disk clone from local to ceph I get 120mb/sec (which is the
network limit from the old proxmox nodes) and only around 100-120 iops which is
the normal for a seq read with 120mb/sec...
Is the vzdump making problems?
It's not vzdump's issue, but qemu's. See
