/proc is a virtual filesystem - no real files, just a "filesystem-like" view into the current state of the system. For example, /proc/meminfo is a summary of the state of the system's memory usage, or /proc/423/cmdline is the command line options for process 423, or /proc/fs/ext4/mmcblk0p2/options is a list of the current mount options of ext4 filesystem on partition 2 of device mmcblk0p2 And /proc/kcore is a look into the current kernel addressable memory space. Some of it will be real memory, most won't. So, you don't need to and shouldn't back up anything in /proc Or for that matter some of the other virtual/temporary file systems, e.g. /sys or possibly /tmp.
