There are many ways of backing up a computer and it is vital that you do. I have seen so many hard drives that have gone west and it’s not alway possible to get the data back again.
Even if you have a back up solution, are you sure it’s working? How will you restore the data? Important things to know. I once went to a new client and for 10 years the had put a tape in the back up machine every night, taken it out in the morning and put it in a fire proof safe. I checked the settings and found that, for 10 years, they had backed up precisely nothing! Hadn’t been set up properly.
I can help you.
