I have a cluster of riscv machines and I would like to back them up on a hard drive connected to one of the machines.
For now I am using rsync and the backups (incremental as well) work fine. The issue arises when testing a full restore using those backups.
More information on this problem can be found here, where I explain the setup and the problem in depth.

I have a cluster of riscv machines (LicheePI 4A) whom I want to back up in case something goes terribly wrong and I need to restore them up from scratch but keeping changes made. I am using a hard drive connected to one of the machines (let’s call this machine backup_machine).
