    [SOLVED] How to browse the files of a VM backup

    I saw that this question shows up often but I still didn't found an answer. On PBS I can browse directly the content of a LXCs backup because it's done file-level. On the other side, VMs backups are done on the block-level so I can't directly browse their content. My final question is...
