pbs

in the past, pbs would refrain from deleting chunks for 24 hours "for file systems that have a low a-time". we are using zfs file system. i know zfs has an a-time for all blocks. does pbs use that? or something of its own? if it's not using zfs a-time, i wanna turn it off for the performance...

Hi all, We have a bunch of VMs that we back up twice a day, to 2 different destinations: once to PBS and once to NFS. I had expected the dirty-bitmap to become invalid because of the alternating backup destinations, but apparently, that's not an issue because one uses vzdump and the other PBS...

Hi! I have very good user experince with pve + pbs solutions and thanks for the good software! Currently pbs system runs on system like - server: PRIMERGY RX2530 M7S - cpu: 2 x Intel GOLD 6548Y+ (core/threads 32/64 per cpu) - memory: 512 G DDR5 - storage: 10 x 15 TB Micron 7450 nvme devices -...

I'm evaluating our strategy for moving our PBS with a valid enterprise license to a new hardware. As we're installing PBS on a new bare metal server, I am wondering how I should move the license. Do I need to deregister the old PBS first, or can I simply register the new PBS and subsequently...

PVE Version 8.4.1 VM in Question - Debian 12 with QEMU-Guest-Agent installed and running as shown via systemctl status qemu-guest-agent When backing up, I get this error in the log: INFO: skipping guest-agent 'fs-freeze', agent configured but not running? However, running this command from...

Hi all, I'm having some issues with the sudden change in fingerprint of my PBS server, obviously as a result of the LE cert rotation. I found this issue through the article here: https://forum.proxmox.com/threads/unexpected-change-of-fingerprint.114313/ My query is, since I have one management...

For VM performance and backup optimization I use separate disks for temporary data like: - swap - logs - system temp-folders - temporary DBs (like tmpdb in MSSQL) - local backups, software packages and many other not-critical stuff Separate disks allow 4 important things: 1) Efficient...

Hallo zusammen Es ist so das ich mein Proxmox extern sichern möchte. Zurzeit habe ich keine Möglichkeit, am externen Ort eine Portfreigabe mit DDNS einzurichten. Mir ist aber gelungen, im CT WireGuard zu installieren und eine Verbindung per VPN zum PBS herzustellen. Was mir noch nicht...

My backups (to PBS) are scheduled to run every night at 1:30am. For the last few nights, I get a warning from my Unifi switch saying that "multiple devices are using IP address 192.168.20.51..." which is the IP assigned to my bare metal PVE node. Nothing special about the node, it's a Mini NUC...

Hello, Recently started using Proxmox VE and want to backup now using PBS. It seems like the regular use case for PBS is for backing up your containers/vms to a remote PBS. I have a small home setup which one server. Proxmox is running PBS in a VM. I have my content such as photos, videos...

Hey everyone, I'm managing backups on my PBS and I've run into a bunch of failed backups that I need to delete. I've attached an image showing the list of backups with their statuses – you can see the failed ones marked in red. Can anyone guide me on the specific commands I should use to...

Hallo zusammen, ich wollte euch auf ein interessantes Open-Source-Projekt aufmerksam machen, das möglicherweise für viele Nutzer von Proxmox Backup Server (PBS) nützlich sein könnte: PBS-Plus. Das Projekt erweitert PBS um zusätzliche Funktionen und sieht insgesamt sehr vielversprechend aus...

Hello I am having issues when I try to run several scheduled backups. For example, with the first VM, once the backup data copying is complete, it takes a long time to formally finish the backup. In this case, it takes 22 minutes and 55 seconds to complete the data copy and then an additional...

Dear Proxmox Forum users, we have a relatively new problem occuring in our proxmox backup server setup. Since some time, more and more weekly verify show failed verify for some backups. There are currently 39 failed Backups, with verifying still going on and some backups were deleted already...

Hi all, Adding this here because I've just spent an hour trying to get to the bottom of why Proxmox notifications work perfectly through a smarthost, but system e-mails are sent directly. Hopefully somebody else will find this useful (or, more likely, future me will find this post when future...

Hello. I tried to get a certificate for my PBS following the documentation but have found many problems. Now it seems that I finally made it by using certbot. root@pbs:~# certbot certonly --manual --manual-auth-hook /etc/letsencrypt/acme-dns-auth.py --preferred-challenges dns...

Hello everybody I have a Proxmox Backup Server with two network interfaces: One network dedicated to backup traffic Another separate network for administrative access (Web GUI) I would like to configure PBS so that: The backup interface listens only for backup traffic...

Hello Proxmox Community, As my offsite backup solution, I decided to go for a Hetzner Storage Box and mount it on my old Intel NUC. I've used Rclone for it, create a systemd for it to auto mount it. I also tried using CIFs for it with the same result. I can see the .chunks and .lock directoy...

I am running PBS as a VM on Unraid, which works perfectly so far. My main datastore is mapped according to the tutorial at https://forum.proxmox.com/threads/how-to-setup-pbs-as-a-vm-in-unraid-and-uses-virtiofs-to-passthrough-shares.120271/#post-522318 via the virtiofs driver. The mapped drives...
