You can have 20 different backup utilities on a single machine and none will interfere with or supplant the others. Each can only restore from the backup format that it creates and uses.
Given that the writing is on the wall for Windows 7 as a whole you would be much better to familiarize yourself with the third-party options for backup and restore that are out there so that you can choose the one that best suits you going forward. Unless you intend to use an unsupported operating system you will be moving to either Windows 8.1, or more likely Windows 10, in just short of 2 years from now. That's not a very long time.
I tried AOMEI Backupper, Macrium Reflect, and EaseUS To Do and settled on the last one mostly because of the ease of use of the interface and the fact that I want others in my household to trigger their own backups. Macrium Reflect is the Swiss Army knife of backup and restore utilities but the interface can be daunting. Since I really needed ease of use as my first priority it lost out. But Macrium Reflect can be installed such that the recovery environment for it is presented to you at boot time, which is really nice since you don't need external media to access it. Since my need to actually recover/restore is very, very infrequent (while some people do it all the time, doing a lot of experimenting on their computers and wanting to bring them back to their last known and favored state quickly) I didn't have a strong desire to keep that particular feature.
And I will add, again, that if what you're trying to do is to replace your existing hard drive with a larger one or an SSD or just another HDD because you have seen certain signs of possible impending failure, it is far easier to clone your existing drive to its replacement before removing it from the machine and then just "plug n' play" the newly cloned drive.
