If you backup via PVE just the virtual disks PVE knows about get backed up, not any disks that were mounted inside the VM (like passthrough of a HBA or NFS shares) If you want to back up those as well you could do that by using the proxmox-backup-client inside the VM; it can back up all...

Hi, you can mount the NFS share in Linux and then create a datastore pointing to that directory. I‘m not quite sure what your second question is, PBS integrated into PVE saves all machines you selected in the backup job as long as the VMs disks have the backup flag set (which is default)

You would need to use the proxmox-backup-client inside the VM itself which is currently only avaible for Linux.

Check this thread on why your 2nd wish wont come true ;) https://forum.proxmox.com/threads/status-logging-diagnostics.78795

Hey, when you make a Disk image you can't view its content... how would you? PBS doesn't know what filesystems or other things hide on that drive. The PXAR Browser only works when you make pxar backups aka file-level backups

:+1: for an option at the VM leveln in PVE to disable fsfreeze during snapshots

You could probably do a backup, boot a VM from a live iso and restore everything to your new disk. It might be easier to install a VM with the bare OS from scratch and then rsync everything over with rsync -aAXv --numeric-ids...

Yes that is possible. Make sure you don't run PBS as a VM on the same PVE though ;) might get tricky when PVE dies and you can't restore.

PBS can use basically whatever filesystem you throw at it. XFS, EXT, NFS, SMB, ZFS, ... The deduplication isn’t done by the storage backend but by the software itself. this means you can definitly go with a „normal“ raid and EXT4 for example. You should be able to use ZFS as well, most raid...

It tries to start the VM And this fails, can you start it by hand and will it start in that case?

I can totally understand the price asked and I think it is justified with what tom said. 6 sockets and you are at that price. For personal projects it is indeed too steep, but for business it is actually quite reasonable, not to say cheap. Hard to find a middle ground here, but I think this is...

Hello, looking through the forum and the included documentation I wasn't able to find any references to the API documentation. For PVE this page exists: https://pve.proxmox.com/pve-docs/api-viewer is there something similar for PBS?

That is possible, you can specify a path to where the datastore is. You will probably get better results with local storage than with NFS though. Usually faster :)

What an exciting day! Congratulations on your new Product! Currently preparing to move all of our PVE setups to PBS :) Oh and I found a typo on the site https://proxmox.com/en/proxmox-backup-server under "Enterprise Support": Proxmox Backup ServeR. Can I have a cookie for that one? :D

Whoops I did mess up when looking in our wiki, it was 0.02. you will use less when you have less files on the system, but since PBS tries to hit 4MiB files you will have quite the amount of metadata.

After using ZFS in a lot of scenarios we developed a rule of thumb of a 0.02 ratio for the special device. So per 1TB if storage 20gb of special device. This alignes with what @fabian uses + some safety headroom.

Exactly, Linux will have cached that file, that’s why you get high speeds :) you need to try it with more files to spill past your avaible Ram.

Hi Elleni, take a look at this: https://forum.proxmox.com/threads/external-pbs-copy.78215

Hello, are the prices for PBS Support Subscriptions already published? Couldn't find any information about them. Will it be similar to PVE?

ZFS only works as long as you have access to a block device. If you are using NFS or other network file systems you are once again limited by this. I don't really see a disadvantage with PBS doing deduplication itself, it keeps it a lot more flexible.
