Trying to calculate required licenses

Hello Community,
I am new to Acronis Cyber Protection for Cloud (M365). I recently purchased some licenses but found that I didn't have enough to backup all the Groups, Public Folders, Site collections, Teams and Users.
I've asked Acronis sales to help me get the correct number of licenses but haven't received a straight answer that was helpful. I turn to you the community members that have experience to help me.
I really want to know what is the difference between a Group and a Team? When I check they both have the same names in both but I am told that the Team doesn't add to the license count but the group does. What is the difference to backup a group vs a team?
Currently I have the Site Collections, Teams and Users backed up properly according to my license count but need to know if I need to double it because of the groups.
Any help is appreciated.
JC
