Third Tier posted a good article on Aug 23, 17 about what is a "good backup". Check it out at
My further thoughts - what are you backing up and where?
And more importantly, how much is it costing?
Did you know that Office 365 backs up your data? For Free!!
It's an easy recovery process. If you need to recover to an earlier version, any user can do that. If it has been deleted, then an admin account has to restore it.
And if you decide you still want backup, there are plenty of 3rd Party vendors that can backup your email and Sharepoint - Cloud to Cloud - no device on premise - for a reasonable cost.
Before running out there to get Office 365, you should review the options -
I like the E3 version (List $240/year) and here's why:
It includes the current version of Office installed on 5 phones, 5 tables, and 5 PCs or Macs. This is important!! When Microsoft announces new features, unless you are on the most current version which would be the subscription version, they most likely will not work. You also get web versions of Office. Most importantly, your mailbox can be up to 50 Gb. If you need bigger, you can go to E5 license (100 Gb). You also get online archiving. So you can upload your PST files and stop backing them up. You also get unlimited One Drive for Business storage, which would be used for individual users. So instead of your people using their personal one drive or drop box, you are still in control of the files and they still have access when away from the office. It also includes Sharepoint, which would be where you put your files. While it is designed to work from web browser, you can also use Network locations which act like mapped drives.
And when you are planning to go to Office 365, don't forget to add enabling 2FA (2 factor authentication).
Update 1: And if you do enable 2FA, don't forget that Oulook (on pcs) and apple email use an "app password". Check out this on how to create one.

Update 1: More cost savings for going to O365 - no more servers to maintain - no hardware costs, no windows and exchange maintenance costs (upgrading to new versions & patching existing ones).
