Stupid question about encryption key for backups

[exaveal]

Hi - sorry, this is perhaps a very stupid question.
The data I show is "fake" - my original key looks simliar, but different.

When I created the entry for the proxmox backup server in my pce, I let the system generate the key. afterwards I took the key and saved the text-string. I was already wandering about the structure, but I did not further think about it.

Now i had to create the connection again, and I wanted to use my already generated key from the past. But I don't know exactly what part of my text-string is really the key I have to enter again.

The text-string I copied:
{"abc":null,"created":"2026-02-01T20:28:47+01:00","modified":"2026-02-01T20:28:47+01:00","data":"lfyQ4nEVVaqcE8tbhfgrzwid74jHatmt4ApK6PWzetds=","fingerprint":"5a:5t:5t:5t:5t:e7:3d:82:b1:b3:5t:5t:45:d7:de:80:a4:f2:5t:ec:8d:1c:5t:5t:d4:2d:0b:5t:5t:5t:d5:f4"}

Thanks!

Hi, @exaveal
If you still have the original system, you probably can retrieve the key from the file
/etc/pve/priv/storage/<STORAGE-ID>.enc

See https://pve.proxmox.com/wiki/Storage:_Proxmox_Backup_Server
and
https://pve.proxmox.com/pve-docs/pve-admin-guide.html#storage_pbs

If you don't have, I would generate a new key and compare the output with the file
/etc/pve/priv/storage/<STORAGE-ID>.enc
to see the structure.

The .enc file contains everything in/including the {brackets}. As I recall from a ways back I just pasted it all in.
