The major differences between FOSS software and paid-for stuff is usually the documentation.
I have found only a handful of FOSS software with decent intelligible documentation that addresses typical user issues. Some attempts at documentation verge on works written by the Devil – almost deliberately ambiguous or misleading, a great majority assume a prior depth of knowledge that rarely exists.
I could add support, but some like VCL have excellent support, while for others it is just non-existent along with the documentation! In fact you can pretty much guarantee that poor FOSS documentation leads directly to a carp support group.
[EDIT] I would like to thank those who have given their views on the packages. I’m going to dump Acronis and try Macrium Reflect, as from my reading it addresses one of the major issues I had with Acronis — viz suspending Shadow Copy if something else such as a VM required access .
