snapshot

  1. CT backup small size

    Hi, I just started using Proxmox a couple of weeks ago. Main goal was to run Home Assitant OS but before that I have tried with different services under Debian LXC (storage ext4). I currently have: 1 - PiHole. 2- Wireguard. 3- Caddy. 4- Media (Radarr, Prowlarr, Sonarr, Jellyfin). Bind mount...
  2. Backup timeout for firewall VM

    Hi, Currently I'm running a PVE node on a dedicated host at a host provider. On that host I have a firewall VM to handle all traffic (including traffic of PVE itself). Storage is ZFS based for the PVE server (boot and VM pools) When I perform a backup of the firewall to my remote PBS server I...
  3. questions about replication and zfs

    Hello, I was hoping to get some clarification about zfs and replication. my VM 104 is running on Proxmox2 in my cluster. I set up a replication task to replicate it to proxmox1 in my cluster. Is the VM on proxmox2 using the snapshot or is it safe to delete the snapshots? (this goes for all...
  4. LVM, LVM-Thin, LUKS, file systems, PVE and PBS, snapshots - suggestions solicited

    I have experimented with Proxmox and Linux (new for me, though I have a unix-like background experience) and set up the following setup: Hardware: standard x86 Core i5 External 2TB SSD RAID (pvehost:/dev/sda) Internal 1TB SSD (pvehost:/dev/nvme0n1 hardware encrypted, key to be entered at boot)...
  5. Standard pve install. Ubuntu 22.04 LTS. Cannot make snapshot

    I have set up a very standard PVE install on an internal NVMe disk and am running a single 32GB Ubuntu VM in that environment. I understand that I cannot create snapshots for that VM because it has 'raw' format (and resides on storage that cannot snapshot itself). I also understand that if I...
  6. Intel Nuc 10th Gen i7 + 2TB NVME initial setup suggestions

    Hi, I’ve just ordered an Intel Nuc 10th Gen i7 (6 cores) with 32GB of RAM and a 2TB NVME disk to build my fist proxmox VE box. I’m going to install as additional package also the backup server since I can’t use a dedicated hardware for it. I‘m thinking about adding in the next weeks an...
  7. ansible - snapshot container with mount points

    I've recently opened a PR which adds the functionality to the ansible.community.proxmox_snap module. The module can now be used with a unbind option, which allows to take snapshots of LXC containers regardless of them having configured mount points. This simple task is achieved by "toggling" the...
  8. [SOLVED] rollback snapshot excluding disks

    Hello, I have a VM with 3 virtual disk stored on the same lvmthin pool. I have a snapshot of the entire VM and i want to rollback to that snap, but only´one disk, not all of them. Is there a way to achieve this? (cloning or backing up the excluded disks is not an option) Thanx in advance!
  9. High iowait when temporary vzdump snapshots deleted

    Hi Community, Recently we have encountered some performance degradation during LXC snaphost. We are trying to understand what is the root of this problem and are there any workarounds. Brief intro. We are running proxmox 7.1-12/b3c09de3 (running kernel: 5.13.19-6-pve) Storage: RAID10 (4x 4TB...
  10. Ubuntu 22.04 Container gets stuck while backing up

    Hello, we started rolling out Ubuntu 22.04 containers using the Proxmox provided ubuntu-22.04-standard_22.04-1_amd64.tar.zst images. When backing up the machines the process gets stuck while creating the storage snapshot 'vzdump'. When the machines are stopped (backup mode "stop", the backup...
  11. Permission denied - when creating a snapshot

    I'm trying to create a snapshot of my VM ID=101 and I'm getting a Permission denied message: WARNING: You have not turned on protection against thin pools running out of space. WARNING: Set activation/thin_pool_autoextend_threshold below 100 to trigger automatic extension of thin pools...
  12. Is there any way that iSCSI can offer snapshots & HA

    Hi Everyone, We've been struggling moving away from a mal-performing CEPH cluster at a customer site for a little while now, however, our NAS supports iSCSI and NFS, but not CEPH or ZFS over iSCSI. Is there truly no solution to include HA, Live Migration, and PBS Live Backups using an iSCSI...
  13. Snapshot / backup encryption

    The documentation talks about enabling encrypted snapshots when using Proxmox Backup Server, but doesn't mention enabling encryption for backup up elsewhere (for example, to a SMB server). Is there any way to enable encryption on all snapshots? I'm hoping to use the web interface to set up...
  14. Snapshot removal "jams" the VM

    Hello, I'm running Jenkins inside a VM ran on a Proxmox VE 7.1.8. The issue is that when I delete a snapshot, the VM enters a locked state, which in turn stops it from responding to requests. I don't know if this is the normal behavior and, if it is, why is it running this way? In my opinion, a...
  15. [SOLVED] Snapshot failed with exit code 2: Permission denied

    I've tried searching around for this one, but being new to Proxmox and Linux once again is proving to be a learning curve. Made my first CT (LXC), using debian-11-standard_11.3-1_amd64.tar.zst to run pi-hole. I've attached the full log of just trying to snapshot this machine by itself. For...
  16. How to Backup a VM and Exclude a Hard Disk

    It's pretty much a simple question, but I doubt the answer will be simple. I hope it will be anyway. So, I have a Windows 10 VM and I have a second hard disk attached for storage for the Windows 10 VM. I'm running Blue Iris on the main (boot) disk of the Windows 10 VM and saving all of the...

    Hi guys, I have a question. One of my host in my cluster can't take snapshot and the other one can. the one who can is in btrfs and the other one, i don't remember the file format is there a way to manual snapshot for the one i can't or i need to change something to be able ? when i go on my ct...
  18. [TUTORIAL] Proxmox Ceph Mirroring - Snapshot Mode

    Like i said in some of my previous posts i have tried ceph mirroring before, and followed the instructions available here. This worked great, but only if you just used virtual machines, and not containers. So this does not work with container disks, because you would need to enable the...
  19. Backup funktioniert nicht mehr - Fehler 255

    Hallo, ich werd hier noch wahnsinnig... ich hab 4 Container in meiner PVE-Umgebung, die ich alle seit geraumer Zeit auf meinem NAS und auf meinem PBS sichere. Seit einigen Tagen werden nur noch drei meiner vier Container gesichert, der eine nicht mehr (klar, Murphy, der für mich wichtigste geht...
  20. Will I screw anything up if I create my OWN zfs snapshots of lxc/qm disks which I have on zfs?

    I keep my LXC container and QM VM disks on a ZFS filesystem. I don't know much about how PVE manages the ZFS snapshots associated with a given container/vm, but I do see in my filesystem that it does have various snapshots which it creates for migrations etc: root@node1:~# zfs list -r -t...
