Hi,
I'm not able to restore backup done on pve1 to pve2.
But I can correctly restore backup on pve1.
Storage is encrypted.

I proceeded as follows:
1. configured PBS storage on pve1, configuring encryption
2. did several backups
3. configured same PBS storage on pve2, importing encryption key (copying and pasting key) created on step 1
4. all backups are visible on the pve2

If I try to restore backup on pve2, process fails after being stuck for a while during the "download and verify backup index"
File restore seems to works from pve2, but, obviously, I can't test any single file

If I try to restore backup on pve1, restore works properly

I'm starting to doubt to be able to restore VMs after a Disaster (like a pve reinstallation on same or new hw).
Any suggestions?

Thank you

Hey,

How did you have declared yours pbs on yours two nodes?
1 or 2 declarations in datastore view?
 
Solved!

1. removed the datastore on pve2
2. rebooted pve2
3. reconfigured the datastore on pve2

The restoration now works properly!

Who knows why...

Thank you for your help
