How would i backup my whole computer just in case of anything to external hard drive? My laptop has an SSD drive. Whats the best way to back up? First time.
In being partial there are many choices out in the market that will back up your system just fine, not just Macrium.
You just need to have an understanding of what you wish to accomplish - do you need an image or data backup program? Yes, some will do both, but some will better suit to a particular task - for me, I prefer Acronis for data backups, but for disk imaging, Macrium.
Example when I reinstall my OS, I simply install Acronis and restore the data I backed up (Documents, Photos, Music, etc) back to the OS. If I'm going to be doing say some disk maintenance, I create a disk image so if something happens, I can restore the OS and all its contents back without having to reinstall the OS and all its data.
Point is there are many choices to choose from based on what your philosophy (choice) is.
Here's but one read, but like anything else not all will agree. Anyway I post not for the point of getting you to chose one of those but to pay more attention to the "What to look for in backup software" section. Again, not all inclusive, but a good basis -
