To check your Mac's model, storage information, memory, and OS version, you just have to go to the Apple Menu and click on 'About This Mac'. You will require at least 2GB of RAM along with a minimum of 8.8 GB of space in your hard drive. You can even use iCloud for storing your photos, music, and other data as a backup. This tool, which is pre-installed in Mac OS, can be used to backup your data to an external hard drive. For backing up and restoring your Mac, the best option is the Time Machine.

Now when I do my weekly disk cleanup/maintenance/repairs, after first running Onyx, I re-boot each Mac from their respective High Sierra backup, and run Tech Tool Pro from there to have it do its "magic" on each internal SSD. So, prior to upgrading to Mohave for each of my Macs)via a clean, fresh, "virgin" installation), I first upgraded Tech Tool Pro to the newest version on each "High Sierra" Mac, then used SuperDuper! to backup each Mac to that Samsung 860 EVO 500 gig SSD, re-started each Mac from their respective "High Sierra" backup, used Disk Utility there to Erase and Format each internal SSD on each Mac, did a fresh, clean, "virgin" installation of OS 10.14.2, and finally "migrated"/copied needed "stuff" from the backup. Micromat has a version of Tech Tool Pro (I rely on it, along with Onyx) that is "mostly" compatible with Mojave. I am actually doing the same thing now, although "backwards". I used it for testing all my applications for each machine, and it was very helpful. I have a Samsung 500 gig 860 EVO SSD, and had two "Mojave" partitions on it for each of my Macs. Yeah, I actually did that (via SuperDuper!) when I was testing Mojave. Fortunately, I always keep a copy of the latest full Mac OS Installation file, and I even still have the ones for Sierra and High Sierra.

Not sure if you can download either Sierra (OS 10.12.6) or High Sierra (OS 10.13.6). You would be taking quite a jump from OS 10.7.5 to OS 10.14.2. The other thing you'll need to do is to insure that any third party (ie, non-Apple) software you are running is compatible with Mojave. Again, this would be downloading the full Mojave OS 10.14.2 file/installer. Your machine can run Mojave, and I would think you could download it from the App Store. But for that, you'll need a backup on an external device. The other way is to do a clean installation of the newer Mac OS.
