-Of course, off-site backups are essential. To do this, I use a small script that powers down the VM, uses ''cp'' with the ''--sparse=always'' flag to preserve space, and then uses tar with pbzip2 compression to save even more space. From my research, bsdtar seems to honor sparsity better than gnutar so install that with ''sudo apt install libarchive-tools''. The ''cp'' command is not optional, moreover, for remember tar will not work directly on an ''.img'' file. Here's a small shell script with a loop for multiple VMs within the same directory. I also added a command at the end that will delete any tarballs older than 180 days.
