    Full backup after moving VM ?

    I am new to Proxmox, so this might be an known issue. But if I move a VM to a new host, the backups see this as a new VM, and so do a full backup (rather than the incremental backup scheduled). Is this by design ? can this behaviour be altered ?? Andy

    ZFS vs. directory storage for containers

    Hi, I'm running a small PVE cluster of two nodes. Both have an encrypted ZFS dataset set up for container storage, using native ZFS encryption. This prevents migrating the containers from one node to another (https://bugzilla.proxmox.com/show_bug.cgi?id=2350). However, if I create a directory...

    How to migrate VMs to new CEPH Cluster?

    Hey, we build a new PVE ceph cluster and would now migrate all VMs from our old cluster. In our old one we have ZFS and directory based storage (raw and qcow2 disks) mixed. How can we do this? We already tested "qm remote-migrate" but this seems unable to migrate ZFS to CEPH Storage. Is our only...
