bigsync can only be used in order to backup single files. However, virtual server environments often mix a number of large files (disk images) with other valuable information. It would be nice if one could just name a directory and say "backup everything, use bigsync for the large files". Luckily, there is such a way. The script below is very simple and might need some refinement, but it is a good starting point for your own backup strategy.

This example script can be used in order to backup multiple running (!!!) virtual machines on your host safely and very efficiently.
