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.
-
Is rsync the best way of doing a full backup in this scenario?
-
What should be the optimal way of restoring back one of the machines in case it is not possible to boot it anymore (fatal failure, worst case scenario)?
Thank you in advance!
