Hi All ;)

I need a good tool to backup whole system on block level rather than file
level and easy to use. I currently need to backup to an USB disc (50+ GB of
data) a system and then reinstall it. In the future if needed I will revert
to the system from backup ;)

What can you recommend?

BR,
Rafal.
