    Request for Enhanced Deletion Functionality in Backup Utility

    I am writing to request a feature enhancement to the web interface's built-in backup utility. As it stands, the utility allows for deletion of one backup at a time, which can be time-consuming when managing large numbers of backups. Furthermore, the current design does not maintain scroll...

    Built-in Backup Regressions I've Noticed Since The Release of PBS

    I've been holding back a long time, but I've decided to go ahead and say what's on my mind. This is the most overloaded drop-down-menu I've ever seen and it needs to be changed back to how it was before! : Instead of trying to use one drop-down to set "day of week" and "Start Time" (at the...

    Snapshot Mode and Resume Not Working When Backup Compression=None

    In Proxmox 7, I attempted to do a "snapshot mode backup" with compression set to "none". During the backup, the Virtual Machine was completely inaccessible and none of its services worked. Also, I attempted doing a "stop mode backup" with compression set to "none". During the backup, I hit the...

    In 7.0, I Can't backup a container to a NFS that worked in 6.0

    I upgraded from Proxmox 6 to 7, by doing a clean install of Proxmox 7, mounting NFS shares, and then restoring all backups. Now, I too am getting the same error talked about in this post: https://forum.proxmox.com/threads/create-backup-fail-with-error-cannot-open-permission-de.32386/ INFO...

    Which Proxmox Backup Compression is Best for Rsync --fuzzy?

    Proxmox provides 3 options for backup compression: LZO (fast) GZIP (good) ZSTD (fast and good) Which of these 3 would be most efficient for "Rsync --fuzzy Synchronization", which uses a previous backup at an offsite destination as the basis for minimizing data transfer of the most current...

    zst

    I just noticed the default backup compression has changed to zst. Proxmox has been pretty great in terms of keeping up with the latest "fast and good" compressions. LZO was new to me before I started using proxmox and now they introduce me to zst. If Proxmox uses it, it is probably pretty good...

    Can Gnome-Desktop be Run from within an Ubuntu 18.04 LXC Container?

    Using Proxmox, I want to do some testing on an Ubuntu 18.04 server with the GNOME desktop installed. Can a LXC container handle a Desktop being installed, or must I use KVM? In my test so far, I've installed the desktop on top of Ubuntu 18.04 server using this one command: sudo apt install...

    Official Documentation on Remove Old Kernels

    Where is the Official Proxmox documentation that addresses the best practice for removing old kernels? So far, none of the posts I've read (in the forum) satisfy me regarding this topic. Partly, this dissatisfaction is due to the fact that different posters are suggesting different practices...

    Should I turn off TSO and GSO on vmbr0?

    In Proxmox 5.1-41, after switching a Windows 2012 VM's Network Device from E1000 to VirtIO (and installing the latest stable VirtIO drivers), I've had users of physical workstations (that use a client/server application hosted by this virtual machine) say that application performance has been...

    Slower Snapshot-Mode Backups after moving from 3.0 to 4.1

    In Proxmox 3.0, my daily snapshot-mode-backup took 37 minutes to create a 78gig backup file. After installing Proxmox 4.1, this same virtual machine now takes an hour and 40 minutes (1:40:00) to create the same 78gig backup file. When I backup the same virtual machine using stop-mode backup, it...

    Proxmox Updates are Downloading Slow

    This last set of updates are downloading quite slow: between 10 to 25 KB/sec (taking over 20 minutes per server). The slowness seems to be server-side, because the local connection is 50mb down and 10mb up, while nothing else on the internet is downloading slow. Its not that big of a deal, but...

    I need to update drivers for my DELL PERC H700 Raid Controller on a Dell R515 running Proxmox. The driver installation utilities (provided) seem to assume I'm running a MS Windows server. On other Dell servers, I've been able to update drivers using IDRAC, but this server doesn't have IDRAC. I...

    Updating all Proxmox Nodes Simultaneously

    I have Proxmox 3.3 cluster, and I've been updating each node individually using the web GUI. I've noticed that when I update one node, it takes a little time before the GUI will allow me to update another node. The NoVNC console fails to showcase the update-command-line if I try to update a...
