After a fresh install of OMV i tried the backup pluguin in case that someting goes grong.
Its configured well but i dont really now how to go to the "previus" state or if i need to mount another image . Here is the Directory , i dont know if with ballenaetcher i can mount the .ddfull inside the compresed archive but i thin im passong another simpler alternative.
Another question is the other archives , dont know what they are .
Thanks in advance
