I have a VM with a NFS share mounted that will be about a couple of TB, how can I exclude it from snapshots?
If I will create a Proxmox HA (I still haven't had a look at it, so I don't know how it works), will it transfer the NFS share mounted with all the data?
Thanks!
I am decently new with Proxmox so forgive a potentially obvious question. I am looking to ensure my VMs are able to take advantage of snapshots. I understand that this is only possible on 'directory' storage. I have a 1TB SSD I am looking to use as both the boot volume for Proxmox and storage...
I have set up my volume to be thin-provisioned. I am trying to snapshot a VM to run updates but when I do, proxmox says I am out of space.
TASK ERROR: zfs error: cannot create snapshot 'VMStorage/vm-101-disk-2@Test': out of space
Here is the output of zfs list:

Hey ich bin ein riesen Proxmox fan geworden und habe aktuell 2 Server bei denen einer Master und einer slave ist, diese sind nicht als HA Verbund konfiguriert.
Sie laufen beide unabhängig voneinande, jedoch sichert der Haupserver einmal in der Nacht die VMs und LXCs via ZFS Sync auf den slave...
I would like to keep ZFS-based backups / snapshots in daily (1 month weekly), weekly (5 weeks), and monthly (6 months) intervals on servers so as to be able to readily rollback if need arises.
How is this accomplished in an automated fashion so as to both accomplish this and purge older...
Hey Everyone. First I hope whoever sees this has a good day :)
We're having an issue with our PVE cluster (v8.1.2) and backing up LXC containers that are run on a ceph pool
It seems that sporadically and without cause, the snapshot stage of our backup job just fails, leaving the container...
Hi everyone,
I'm looking for a method to put a virtual machine into a backup state on Proxmox, allowing me to safely copy its files without interrupting its operation. I prefer to avoid using the default dump tool or backup utility, as I intend to create my own backup solution.
If anyone has...
When I create a snapshot of a VM:
a) is that a backup?
b) will it back up all my virtual disks? E.g., If I have a virtualized storage server will it back up the vdi that I set up for bulk storage along with the boot vdi?
Thanks.
Hello, I'm new to the forum and new to using Proxmox, I have a problem that from time to time automatic backups are made with the "@--head--" mark (what is that? :) ), they take up space and I can only delete them from the terminal, but after some time they appear again. Could someone tell me...
Scenario:
2x Clustered Servers, with StorageZFS replicating between them.
Problem:
When performing the Snapshot of VM 108, several VMs crashed, and I had to reset to go back.

Coming from this thread: https://forum.proxmox.com/threads/understanding-storage-requirements-for-snapshots.128444/
I'm looking for a way to do backups of running VMs without downtime. The idea is to have a full backup, that can be moved to other parts of a cluster, or different proxmox...
Reading these articles: https://pve.proxmox.com/wiki/Live_Snapshots and https://pve.proxmox.com/wiki/Storage
Basically tells me "snapshots is something you can do" but nothing more.
Recently I tried doing a snapshot and got this as output:
If I check with lvs I do see it in the output:

Hi all,
I've encountered an issue when I try to take a snapshot of a VM or CT where the disk as moved to a shared NFS storage.
In the Snapshot section there is a warnings: The current guest configuration does not support taking new snapshots
A screenshot below:
This is the root disk...
Let's say I have a VM that's a clean version of the OS, snapshot with the name "clean". I then patch it with the latest patches. I now want to "move" the "clean" snapshot to point to the patched state.
At the moment the only safe way to do that is to snapshot the patched state with a new name...
Hi
since 2 weeks i cant create any snapshots for any VM i created on my proxmox server.
I dont know what to do because running the snapshot in GUI or CLI results in
zfs error: cannot create snapshot 'SSD_ZFS/vm-<ANY_ID_HERE>-disk-0@<CHOOSE_ANY_SNAPSHOTNAME_HERE>': dataset already exists
Even...
Hi all,
I've been trying to follow online tutorials of taking snapshots of VMs and to do this it requires the disk to be a file level storage (except lvm-thin(according to documentation). So whenever I use ZFS as the disk and then create a VM, it still doesn't allow me to change the format...
Hi,
we have a Proxmox cluster with CEPH. Can we somehow enable automatic snapshots like with ZFS?

If yes, how does it work?
Hi all,
I've had a look through the threads for users who have experienced the same issues with being unable to take snapshots on VM's, however, my VM's are using the qcow2 virtual disk format.
It weirdly seems limited to just the Windows Servers, however, Windows 10 Pro and Linux servers seem...
I'm about to make some big changes to my Proxmox installation (I'm going to try VGPU Unlock), and I would like to be able to revert back to my present state if something goes wrong.
Since I've installed Proxmox in a ZFS file system, is there any way to do what I want?
