Encrypted backups restore question (Yes, I have the key)

[shadowsix]

Hello All,

I am a bit newer to PBS and PVE so I am looking for a process to restore from my existing backups here's what happened:

My PBS was on a PVE host that is not working right now (Separate issue) and I need to restore a CT with important data on it.
I created a new PBS and got my ZFS datastore back into PBS already and added back to the host I can see the backups fine
When I go to restore I get this error:
recovering backed-up configuration from 'usb-backups:backup/ct/105/2024-09-15T02:00:39Z'
Error: missing key - manifest was created with key 43:61:d7:e1:53:f5:4c:b2
TASK ERROR: unable to restore CT 116 - command '/usr/bin/proxmox-backup-client restore '--crypt-mode=none' ct/105/2024-09-15T02:00:39Z pct.conf - --repository root@pam@10.10.10.209:usb-backups' failed: exit code 255

With my key in hand, where do I go / do to get it inserted to the restore or decrypt the backups to get passed this error.
I seen other post here but they didnt have the key whereas I do any help/feedback greatly appreciated

I did find under storage I can edit Proxmox Backup Server "usb-backups" datastore then go to the "Encryption tab"

It was set to "Do not encrypt backups" since I recently rebuilt new PBS and imported the old ZFS USB drive that had the existing backups
Now the key I have is not in a "file" format to upload its saved as just a text note in my vault.
From there what file extension do I need to save as when I paste the key into a text editor is my other question?

I may have this solved its resolved the CT I need restored is restoring now
What I did per my last response I found this https://forum.proxmox.com/threads/solved-share-encryption-key-between-two-pbs.86893/
It mentioned .enc file so I made this file with notepad "pbskey.enc" and pasted my text of the key into the file it uploaded successfully
I no longer have the "Error: missing key - manifest was created with key"

I figured I'd leave this up for anyone who runs into a similar situation and has been working on infrastructure stuff all day not paying attention to it was that easy!
