    System freezes during backup

    I'm having regular, but not predictable, issues with my whole system locking up during vzdump backups. Sometimes I'm able to access the host via the GUI, and all the VMs and containers have question marks, sometimes I can't access it at all, same goes for ssh. I've seen a few threads around...

    Fast second layer backup using the --rsyncable key and rsync.

    Hi! As we know, gzip (or pigz) launched by vzdump is always launched with the --rsyncable switch. By default. So we can use rsync to quickly back up a backup file to another network location. I wrote an example script of a subsystem called SLB - Second Level Backup. This works fine, but only...

    Trouble with vzdump/backups (especially windows)

    My linux VMs back up fine, but the windows ones do not. I was using zstd and the backups kept freezing (I couldn't stop the process without restarting the node), so I am trying gzip now. This time, the process at least ends without hanging, but there are still errors on the windows VMs. I'm...

    [SOLVED] USB-Stick als VzDump einrichten

    Hallo, ich möchte einen USB-Stick als Backuplaufwerk im PVE (v8.04) einrichten. Als root suche ich mir via <ls -la /dev/disk/by-id/> die UUID des Sticks heraus, und binde ihn via </etc/fstab> ein. Als Mountverzeichnis wähle ich z.B. </mnt/USBStick>. Danach <systemctl daemon-reload> und ich...

    6.2 to 6.4 update pvedaemon failure with pve-manager held back

    In preparation of wanting to upgrade to version 7, I read in the upgrade notes that it was preferable to update to 6.4 before proceeding.

    VZDump and S3 don't mix well

    Hey, Straight to the point, the "move" operation at the end of VZDump kills it if the destination is S3 backend (for which move is actually copy&delete). Currently I'm using rclone to mount S3 bucket. Would it be possible to add a switch that would write backup directly to the destination...

    VM restore options - /var/tmp

    Today I was moving some VM's manually between servers via backup&restore, and I noticed that my system copies the dump file all okay between servers, but when I start the restore process, it is really sluggish and my I/O wait time increases. This is more of an intro to my actual question, but...

    Backup VM to another Disk (ask for advice)

    Hi, everyone. I am new Proxmox user. I have 2 Dell R740 servers. Both have 4x 4TB HDDs. I want to make 3 of them RAID 5, make 1 of the other server's VM backups, the other one in the same way and save its VM backups to the 1 HDD. Do you think this makes sense?

    [SOLVED] Determine if backup is run interactively vs scheduled

    Within a vzdump hook script, how can I differentiate scheduled backups from those run interactively via the web UI? There doesn't appear to be anything in env I might use to do this.
