This feature +is only available for backups on a Proxmox Backup Server. + +For containers, the first layer of the file tree shows all included 'pxar' +archives, which can be opened and browsed freely. For VMs, the first layer shows +contained drive images, which can be opened to reveal a list of supported +storage technologies found on the drive. In the most basic case, this will be an +entry called 'part', representing a partition table, which contains entries for +each partition found on the drive. Note that for VMs, not all data might be +accessible (unsupported guest file systems, storage technologies, etc...). + +Files and directories can be downloaded using the 'Download' button, the latter +being compressed into a zip archive on the fly. + +To enable secure access to VM images, which might contain untrusted data, a +temporary VM (not visible as a guest) is started. This does not mean that data +downloaded from such an archive is inherently safe, but it avoids exposing the +hypervisor system to danger. The VM will stop itself after a timeout. This +entire process happens transparently from a user's point of view. + [[vzdump_configuration]] Configuration -------------
