vzdump

Preface While I am basically sure this is documented somewhere I was not able to find a compact guide. And I was never in a situation where this was necessary... yet. What I had found is https://pve.proxmox.com/wiki/VMA and the man-pages of the required commands, but no “walk-through”...

Original post from the DE support board translated: After this I was informed in a now deleted comment that there is no functionality like this and using Proxmox Backup Server was recommended. Our Proxmox Backup Server deployment is in the works but will still take some time, so we need a...

I'm struggling with all the 'deprecated' params in vzdump in order to NOT sent any notification at all. The vzdump is called in a bash script and none of the params help to discard the notification - as this is called via my own separate script I don't want to change any global vzdump...

My backup target filled up. Using other backup software in this situation, I would typically invoke a prune or retention process (also called a zero-byte backup w/ subsequent retention) which would usually bring it back from the cliff. Then I could adjust my retention settings to avoid this in...

proxmox 8 - 5 nodes in clusters - only 1 node has this issue - node 5 on node 5 - vzdump backup schedule is set for guest qemu vm issue -> but 2 vzdump instances run even though there is only 1 schedule both vzudmp process have different process id and task this causes guest qemu vm to...

Hi folks, My cluster is a set of 4 HP 260 G1s (i3-4030U, 16GB, 240GB boot SSD) connected to a TrueNAS Scale system providing shared iSCSI LUNs on both SSDs and HDDs for VHD storage. Originally I had each node backing up to a separate NAS via NFS. I've now removed that NAS as it was giving me...

hi, after upgrading from 8.2.2 to 8.2.4 backups of one random lxc container stopped working, on this node there are 14 lxc containers, backup of 13 working fine, only one have problem (size of lxc with problem is 110GB, but it should not be issue, i have also 200, 320 and 340 gb, and backup...

Hello, I am experiencing an issue with email notifications for backups on my Proxmox server. I followed the suggestions from the documentation and configured the "Notification Matcher" rules as follows: match-field exact:type=vzdump However, when I run a backup, no email is sent, even though...

Seit Wochen macht die tägliche Sicherung auf einen Cluster Knotens eines PVE 8.1.4 auf/per den PBS 3.1-4 Storage Probleme. Die VMs liegen auf mehreren NAS LUNS die per LVM/ISCSI + Multipath und 10GB eingebunden sind. Der Fehler tritt bei den VM Sicherung sporadisch auf: ERROR: Backup of VM XXX...

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...

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! 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...

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...

While currently not supported I have patched the perl module for LXC. /usr/share/perl5/PVE/LXC.vm You may apply the patch via patch /usr/share/perl5/PVE/LXC.pm LXC.pm.patch This is the content of LXC.pm.patch: --- /usr/share/perl5/PVE/LXC.pm 2023-06-24 15:08:37.000000000 +0200 +++...

Hello, I'm currently facing a strange behavior while Proxmox executes backup(vzdump.) When Proxmox starts backup, it also uses swap space, even if there is free RAM, anyone has any idea why? swappiness already changed to 10. proxmox-ve: 7.1-1 (running kernel: 5.13.19-6-pve) pve-manager...

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...

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. Unfortunately, something has gone wrong during the update/upgrade from 6.2 to 6.4 and a few packages are being held back. Now I'm no longer able to access the...

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...

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...

Hi, I backup some VMs using SSH with vzdump redirecting to stdout, similar to the command below: ssh root@pve-server vzdump 100 --mode snapshot $VZDUMP_PARAMETERS --stdout > ${SERVER}_${NAME}_$(date +%Y-%m-%d).vma 2> >(tee -a ${SERVER}_${NAME}_$(date +%Y-%m-%d).log >&2) But I noticed that if...
