Can't create a full backup : says system in in freeze state

Hi,
I’m running Home Assistant OS on a RPI4, versions as follow:
Home Assistant Core 2022.6.3
Home Assistant Supervisor 2022.05.3
Home Assistant OS 8.1

I’m trying to migrate to a small PC (HP ProDesk Mini), and want to create a snapshot so I can restore my settings on the new PC. However, I can’t create the full backup, it spins forever, and when I want to retry after refreshing the window, it says the system is in freeze state.

How can I solve this issue and complete my migration ?

Thanks in advance.

Just checked the logs from CLI, I see this:

It may be in a freeze state because it is still backing up?

What usage are you seeing at Settings > Storage?

it’s just beaucause you are in progress of a backup. you need to wait for the backup to finish to make another one
