Good morning,

I just upgraded from proxmox 7 to 8. I started with a new installation to have a clean proxmox. Before I made backups on USB media with :
Code:
mount -o rw /dev/sdb1 /media/usb-disk
mkdir backups-proxmox
Code:
DATACENTER > Storage
ADD > directory
ID : usb-proxmox-backups
directory : /media/usb-disk/backups-proxmox
Content : Disk Image + VZDump backup file
Dans DATACENTER > Backup
Add

After checking, I have my backups on the USB key. so I proceeded to format my hard drive and install.
Once Proxmox 8 was installed, I did:

Code:
mount -o rw /dev/sdb1 /media/usb-disk
then in the PVE interface the USB-PROXMOX-BACKUPS > BACKUP and select the VM and RESTORE

My files are in tar.zst and vma.zst


When I restore my files I have 3 different errors:

- 1st error: Restoring lxc-100.tar.zst
Code:

- 3rd error: lxc-103-tar-zst
Error: archive contains no configuration file (500).

I don't understand why no archive can be restored... It looks like I lost everything... What is your opinion?
 
I'm coming back to the forum even if I haven't heard back... For several days I've been on proxmox to reinstall everything. Unfortunately for me, I lost a lot of datas :(

I tried reproducing the backups to figure out why it's not working.

If I go to Datacenter > Backup and create a backup from the PVE to the USB stick, I cannot restore.
I have this error: Error: archive contains no configuration file (500).

I need help setting up an automatic USB drive backup that works... Why does VM backup work but PVE backup doesn't? I don't understand why the archive have not a configuration file... The task is Ok :

Did you try with a different USB drive?
In your first post there are data corruption errors in the log, so maybe the drive/stick is faulty, maybe the cable is bad, etc. I've had to do a few backup/restores of CTs this weekend on PVE8 and they all worked ok, so backup/restore, in general, works.
