I forget the mandatory disk layout conversion from GPT to MBR.
I can't help you on this topic on my free time, but you will find examples on the web.
It's same as Windows 10, switch from UEFI to Legacy/CSM.
Don't forget to backup VM before attemps.
yes in hardware option,
but Windows require boot loader adjustments, not really a Proxmox VE side.
edit2: GPT to MBR disk layout conversion required too.
edit: Windows 11 officially require UEFI but works in SeaBIOS (+ clean install / inplace...
I don't think OP use qcow2 as "Format" is greyed out to raw , which confirm it's already block based.
@kunwarakanksha : is ZFS or Lvmthin ?
is BIOS server power/energy set to Maximum performance ?
Size reported is the whole partition size where folder is stored.
By default with ext4/Lvm install, this is the whole Linux OS system size + the stored iso.

In my opinion you setup the wrong comparison:
1 single drive with ZFS with so low IOPS 4k random R/W against a nas with more drives and probably cache, will not fit a real compare.
If you want zfs, so do it i do, use only ssd (SATA3) as ZFS...
Ah, good catch. That's the binary with debug info and without stripping. I noticed that there is a path: libproxmox-backup-qemu0-1.5.1/debian/libproxmox-backup-qemu0/usr/lib/libproxmox_backup_qemu.so.0 as well which seems to contain a binary of...
Success! My colleague Daniel Škarda and I have managed to produce a patch. Now the restore completely saturates a 10 Gbps link (we don't currently have anything faster to test).
If you want to test, please let me know and I can send you the...
Main issue is when PBS is too slow,
like doing backup directly over WAN.
Or like multi backups to one HDD.
If you use incremental SQL backup system, set the VssOption option to the numerical value of 5 in Windows registry to not break the SQL...
Another Option might be to use NFS with your NAS, then you could use QCOW disk images with snapshot support. It's still a single-point of failure and you will still need a qdevice. You could reuse one of the old nodes for that though...
