UdoB replied to the thread PBS with a volume >100 TB — how do you handle verify?.Assuming HDDs: You mentioned Raid6. This gives you the IOPS of a single disk. A verify need to read the actual data, calculate the checksum and compare it with the stored original checksum. There is no single, large file to be read. Instead it... -

Like.
HW Raid or ZFS RAIDz won't cover whether the backup is still consistent. So yes: Imho it's absolutely necessary. What kind of storage are you using? HDDs, SSDs or a fusion pool ( HDDs with SSDs as special device in zfs)? If you can't afford... -
UdoB reacted to Falk R.'s post in the thread [SOLVED] Soll ich die Community Lizenz kaufen? with Like.
Noch mal zur Info, das ist keine Lizenz. Du kaufst nur Subscribtion und produktiv empfehle ich immer mindestens Community. Dann kannst du dir ohne Gedanken machen zu müssen die Patches des Enterprise Repo installieren. Ich habe in den letzten...

In einer Produktivumgebung würde ich natürlich nur mit einer Subscription arbeiten, denn nur da bekommst du getestete Enterprise-Updates. Ob Community oder eine größere Lizenz hängt von deinen Linux-Kenntnissen ab. ;-)

Was heißt "wir"? Unternehmen/Verein/Familie? Je nachdem was zutrifft, ändert sich die Aussage. Bei einem Unternehmen wäre ich eher bei einer Basic oder Standard Lizenz. Bei einer Familie/Homelab würde ich sagen, dass es auch ohne geht. Ansonsten...

Hi @mouse51180 , welcome to the forum. You are mixing Debian (PVE userland) and Ubuntu (universe repo). What happens when you run "apt update" now? What is in your: cat /etc/apt/sources.list ls -al /etc/apt/sources.list.d/ cat...

Ganz ehrlich, ein frisches Backup rettet dich im Ernstfall auch nicht. Ich habe das zum ersten Mal vor 20 Jahren erlebt wo jede Woche ein frisches Full auf Tape geschrieben wurde. Leider waren die Quelldaten auf dem Server defekt gegangen was...

UdoB replied to the thread Node maintenance mode UI.Your "+1" is probably better placed over there: https://bugzilla.proxmox.com/show_bug.cgi?id=6144, already mentioned in #47. You'll also find a patch already mentioned in the last comment.
