snapshot

Greetings I've recently moved from proxmox 3 to 5 and I'm trying to use it fully. I'm using zfs and lxc and I'd like to automate the snapshoting: I want to mimic going to the GUI and clicking "Take snapshot". I can go directly, that is, do a zfs snapshot and alter the .conf file, but is there a...

We are trying to make a 2nd Domain Controller on a different server and I was going to try to take a snapshot of our existing Samba Domain Controller and copy that snapshot to new location, change the IP settings, name, etc... and start it up. Has anyone ever tried this before?

Does passing through harddisk disable the vm's snapshot functionality? Hi, I have a vm, used to be able to take snapshots fine. But now the snapshot button is greyed out. The only special point I can think of is it has passing through harddisks. So with passing though hd, can I still do...

Hi, I recently noticed that in the morning my VM's are all down. When looking at the logs of the backups, it seems that the snapshot backup is shutting down the VM's. I'm currently running the latest Proxmox version: root@proxmox:~# uname -a Linux proxmox 4.4.35-1-pve #1 SMP Thu Dec 22 14:58:39...

the gui only offers Full Clone for VMs on ceph volumes; ceph should be able to create linked clones fast and easy (as well as light snapshots, by the way). Full Clone creation doesn't seem to use ceph and thus extremely slow. PVE full clone was created in 43 minutes, while doing it in the...
