That's correct.
JUST TO CLARIFY... There are two different types of "backups" you might be concerned about with Lightroom. One is backing up your original image files for safe-keeping. The other is backing up your LR catalog itself, with all your selections, edits and adjustments.
First - maybe you're already aware - your photos actually aren't "in" Lightroom at all. LR is actually a database of sorts that contains smaller "thumbnails" of your images along with the selection, editing and adjustment notations associated with each image. LR is "non destructive", meaning it doesn't actually apply any of these changes to the original image until you "export" the image from LR... and even then it will want to do so on a copy of the image, not the original.
Original RAW files are
never directly changed because LR has to convert them to a JPEG, TIFF or other type of file for them to be usable. The original RAW is untouched, but LR maintains a "sidecar" file with info about how you want the conversions done, the changes and edits you made.
If the original from your camera is a JPEG, LR will ask you before making any direct changes to the original... it will want to make a copy with changes instead (unless you override it and force it to change the original... which may not be a good idea).
Now, regarding the two types of backups....
1. Image backups: During LR "Import" you have option to have LR save backups of all your originals to the location of your choice. For safest backup this is usually best done to an external drive of some sort or to "cloud" storage. I.e., backups should be somewhere other than the same drive as the originals. Best of all is something that will be kept "off site". Of course you can simply make backups yourself by copying the originals via the computer's operating system. But an advantage of having LR make your backups this way is that it will continue to associate the selections and changes you make to your images within LR to both the originals and the backups.
2. LR catalog backups: In LR preferences you can set the program to perform backups automatically in a variety of ways. You can set it to do so each time you exit the program... or to perform weekly backups.... or whatever interval you're comfortable with. It's up to you... It takes some time for LR to perform the catalog backup, so you'll have to weight that against how much work you'd be willing to lose and have to re-do later, if something happens to the catalog, since it's last backup. Maybe once a week is adequate. Maybe not.
During the LR catalog backup it is also possible to have LR "optimize" the catalog. This helps it perform better and is a good thing to do. Once again, it might be most ideal to save your LR catalog backups to a separate hard drive... not the same one where it's keeping the original catalog (also can be a different drive in the computer, if it has multiple drives... or an external drive of some sort).
Make note of where LR is saving the backups and check if it's replacing the old one whenever a new backup is created... or if it's keeping each successive backup (in which case you will probably want to clean out old ones periodically.)
Personally I back up my images before doing much work on them in LR... right after downloading, importing, sorting and renaming them (which are always my first steps). NOTE: I always leave the originals on my memory cards, until I am sure the downloads and backups are safely done.
And I have my LR set up to ask me if I want to backup it's catalogs weekly, upon exit. I will go ahead and make a backup when I've done some actual editing work on a new batch of images or made any significant changes to older files in my archive. But if I was only using LR to locate an older image and didn't make any changes, there's nothing new to backup so I'll tell it to "skip". Note that for best performance you should occasionally go ahead and optimize, even if you don't backup. Also, LR catalogs can start to bog down and run slowly when they contain 100,000 or more images. Create additional catalogs as needed. (I create a new one for each year and currently have sixteen catalogs.)
