How to download a disc VM from backup (proxmox VE)

[alex.d]

1. List of backup (Proxvom VE)
pvesm list 192.168.1.15 | grep 915
2. Restore VM from backup to new VM without LVM store.
qmrestore 192.168.1.15:backup/vm/915/2023-02-01T14:11:10Z 916 --storage PVE-raw
3. Move disk another store
mv /mnt/pve/PVE-raw/images/916/vm-916-disk-0.raw /mnt/pve/PVE-raw/images/template-916.raw
4. Destroy VM
qm destroy 916
5. Convert VM .
qemu-img convert -f raw -O qcow2 /mnt/pve/PVE-raw/images/template-916.raw /mnt/pve/PVE-raw/images/template-916.qcow2

This path is not comfortable and long.
Maybe there is an opportunity to somehow download the VM disk directly from the node via the CLI

Hi,
what is your motivation for creating the qcow2 image from the backup? There is the option to create VM templates https://pve.proxmox.com/pve-docs/chapter-qm.html#qm_templates, not sure if that satisfies your needs.

Feature requests please to https://bugzilla.proxmox.com/

you could use map + qemu-img convert

$ proxmox-backup-client map ...
Image ... mapped on /dev/loopX
$ qemu-img convert ... -O qcow2 /dev/loopX OUTPUT_FILE.qcow2

to directly read from PBS into a qcow2 file, for example:

$ proxmox-backup-client map vm/800/2023-01-16T12:28:10Z drive-scsi0.img --repository test@pbs@localhost:tank
Password for "test@pbs": 
Image 'test@pbs@localhost:8007:tank:vm/800/2023-01-16T12:28:10Z/drive-scsi0.img' mapped on /dev/loop1
$ qemu-img convert -p -O qcow2 /dev/loop1 image.qcow2

$ qemu-img convert -p -O qcow2 /dev/loop1 image.qcow2

In your version, I need to pass the password in clear text. Is it possible to do this by key or in some other way. The main task is to download the disk image!

# proxmox-backup-client map vm/911/2023-02-02T06:30:03Z drive-scsi0.img --repository test@pbs@192.168.1.15:Bac-St

Error: unable to open snapshot directory "/mnt/storage/Bac-St/vm/911/2023-02-02T06:30:03Z" for locking - ENOENT: No such file or directory

 

[fabian]

that probably means that the snapshot you requested does not exist..

It's my mistake.
It's work:
proxmox-file-restore list vm/911/2023-02-02T21:00:26Z / --repository 192.168.1.15:Bac-St --ns Test-1
Thanks


List will by default only output the backup snapshots of the root namespace itself. To list backups from another namespace use the --ns <ns> option

Is it possible to download the img file?
Without using an intermediate mount?

No, this is because the backup files are stored as chunks on the Proxmox Backup Server for efficient deduplication, so in order to recreate the original image from the chunks, you need the proxmox-backup-client.

Only proxmox-backup-client map and qemu-img convert?

you can restore into a raw image file (using proxmox-backup-client restore, but not directly into a block device or a different image file format like qcow2
