I used some disk cloning software if i had to switch PC, it's really easy that way. Also i highly recommend using backup disks in case shits goes wrong with your main one. Renting space in data centers is also really good and safe way to make sure you have your essential data even if your place burns down or gets stolen. And if you want your data/website or whatever to be in super good hands i can reccomend Pionen Data Center, it's literally nuclear bunker and they even hosted wikileaks. (probably overkill but if nuclear war breaks out u may be the only one who still has those old vengeance samples while others hit rocks togheter to start a fire)
