Snapshot compressed with:
- gzip takes: 479m Mb
- xz 3 level - 272 and takes 4 minutes
- xz 9 level - 239 and takes ~ 30 min
It is possible to use pixz utility that will run compressing
on multiple cores, but i dont think it is wise to depend on it,
because when master host will be installed on vm - it may take
very long time to generate snapshot
