    Well, it already is lowered. The "classic" limit was 50 % of the system Ram for many years; the compile time limit is 90 %, afaik ;-) @xybo gave the correct hint: check the actual hitrate while running your specific workload.

    muss es ja auch nicht (wenn Quelle und Ziel ZFS sind und ZFS selbst bit rot erkennt) ;)

    To clarify, I mean a special device on SSD seems critical for the OP's stated HDD configuration using parity and the desire for performance.

    I am not 100% sure on that one. Sure, I have pretty low backup requirements (around 20 Linux VMs and 8 Windows VMs, 182 snapshots at 1.5TB) but I only see 800MBit/s and 500 IOPS peak. So I am not entirely convinced it would be much slower with...

    Solange keine Portfreigabe drauf zeigt, bleiben die anderen CTs und VMs geschützt, die hängen im LAN und von außen kommt da nix an. Das Problem ist, wenn du einen Port aufmachst. Den Container würd ich dann in ein eigenes Netz hängen (eigene...

    mTLS ist ein guter Punkt, nutz ich für ein paar interne Sachen auch. Bei PVE selbst würd ich aufpassen: die Web-UI hinter einen Reverse Proxy zu hängen macht wegen der WebSockets (noVNC, xterm.js) und dem API-Traffic gern Ärger, und wenn der...

    Bei mir läuft 8006 ausschließlich übers VPN, kein Proxy davor. PVE-Firewall auf Datacenter-Ebene mit Default DROP und eine Regel, die 8006 und SSH nur aus dem VPN-Subnetz erlaubt, das wars. Wenn von außen eh nichts ankommt, brauchst du da keinen...

    But it is :) A Hardware RAID5 with 4 drives will give you exactly 75% storage efficiency. A ZFS RAIDZ1 with 4 drives will give you between 50% and 75%, depending on padding and pool geometry. Which in return depends on your zvol and dataset...

    You shouldn't just "consider" it except you enjoy getting hacked due to unpatched security issues: https://forum.proxmox.com/threads/proxmox-ve-7-is-vulnerable-to-some-type-of-0day-rce-non-auth.186078/ If you are not able to keep you production...

    Maybe this (which I found using this search) will help: https://forum.proxmox.com/threads/recover-from-grub-failure-cant-find-lvm.121861/#post-529751 Your Proxmox VE is many years out of support and vulnerable to a lot of things. Please install...

    IsThisThingOn replied to the thread Official status of support for multiple backup solutions.
    Sure. VEEAM supports PVE, so PVE backups are supported by VEEAM. PBS supports PVE, so PVE backups to PVS are supported by Proxmox. Support means that someone will pick up the phone or give you the option to write a ticket. As a rule of thumb...

    IsThisThingOn replied to the thread Official status of support for multiple backup solutions.
    True, but at the same time, why would I want Support from Proxmox for my backup tool? IMHO it does not matter, what PVE supports. If I use VEEM for my proxmox backup, the only thing that matters is IMHO that VEEAM supports backing up a PVE host...

    Not sure, but is it maybe just the missing ' ? That could also be the case. I created the user on pbs, so that is why I am using that. I also just gave it full admin rights and deleted the user afterwards.

    Sorry for your loss, but why would anyone do that?

    IsThisThingOn replied to the thread PBS with slow backend.
    Depends. Rsync should be pretty good at batching metadata over slow networks. AFAIK the bottlneck should be the storage metadata performance. PBS on the other hand reads ALL you lokal data, and creates a hash. So you lokal storage and CPU...

    Yeah, my redacted IPv6 Jup, not a problem. Proxmox GUI just displays the pools, no matter how they are created. But you probably could also create it in the webGUI.

    Then the TLS speed should be your bottleneck, since the PBS storage is too slow to write above 200MB/s. That is pretty bad for 2-4MB chunks IMHO. But to be expected with a 6 wide RAIDZ2. You could switch to mirrors, that way you should be able...

    Run the benchmark on PVE with PBS as destination. Then run the benchmark again on PBS. Post both results

    Can you run the benchmark command on your PBS host? My setup is some pretty old hardware with six disk RAID10 with 7200RPM WD4002FYYZ: (Forgot to mention, this is with mirrored SSDs as a special device.)...
