There are two major categories of information to back up: (1) the operating system ("OS"), including installed programs and their configurations and (2) "data," such as documents, pictures, music, and video. My OS, and only the OS, is stored on C:\. I presume necessary program configuration files are also on C:\.
"Data," in contrast, is usually added to the system either by programs creating data files (like Word or Excel) or by importing "outside" data, like other documents, music, photographs, and video into the file system.
Windows 10 typically stores created data in set folders in C:\ Users\xxx such as
Some Windows programs, unfortunately, put their data files somewhere else, meaning you have to track them down to back up their data separately. For example, Outlook puts its data file (Outlook.pst) in a hidden folder in C:\Users\xxx.
2. Default Locations
If a computer has at least two disks, I move My Documents, My Music, My Pictures, and My Videos off the C drive so that C contains only OS and programs, making it easier to reinstall the operating system and programs, without affecting the data, if that ever becomes necessary. I normally put them all on D:\ along with whatever other data folders and sub folders I have created.
Where I have an SSD for D:\, I have My Videos on D:\ but have less used videos on the mechanical archive drive (E:\in my case) so as to not overload the SSD with large video files. Also, any other large infrequently accessed data goes on the third drive, the mechanical HD. Of course, on one drive laptops everything has to stay on C:\.I do not partition the one disk systems between OS/Programs and Data, although I suppose I could.
4. Backup Plan Overview
a. Set Up
All data on all computers is backed up (with versioning) nightly to my NAS, a Synology DS216. I use Synchback rather than the back up program on Synology or the Windows back up program. Synology has two disks in Raid 1 so all backups are duplicated.
In addition, some data like Outlook.pst files, Quicken files, etc, are separately backed up nightly by SyncBack Pro from their default location (usually C:\Users) to something like D:\Documents\Backups on the computer with the files being backed up If the system has more than one disk, the back up folder is on a separate drive (such as D:Documents\Backups). My daily backup locations (D:\Documents\Backups) is included in the nightly SynchBack Pro backups to the NAS.
I sporadically manully back up the data on each computer to an external USB 3 hard drive.

d. Shared Data on Main
Some data (like uninstalled programs, archived data) is uniquely found in the Shared Folders on Main E:\Share. All computers WHS. Because duplication was removed from WHS 2011, I mirrored two HDs to hold Shares, a quasi Raid 1. It is backed up (second copy) twice daily by the WHS built in back up program to the external 2 TB USB 3.0 drive.
I also use SyncBack Pro daily to backup Shared Folders on WHS to a spare mechanical HD on TJ09, giving a third copy. That spare HD is backed up nightly to WHS meaning a fourth copy goes back to the WHS from whence it came (and gets backed up twice daily to the WHS external HD). Ps. WHS is supposed to deduplicate the shared and backed up data.
B. Specific Items to Backup
1. MS Outlook
The native location of the Outlook data (e-mail) file is C:\Users\xxx\AppData\Local\Microsoft\Outlook\Outlook.pst. It is a hidden file. Both TJ09 and PC7B use Outlook. On TJ09 the original file is in its default location C:\Users etc. for speed. With SyncBack Pro I back it (Outlook.pst) up nightly to F:\Backups\Outlook bak\ so it will be on a separate disk. Separate backups of C:\Users\...\Outlook.pst and F:\Backups are made every night by SyncBack Pro to Z. by WHS. And both sites are backed up nightly by WHS.
Also, Outlook has a manual backup function which I set to D:\Backups\TJ09 BAK\Outlook manual\backup.pstOn PC7B I left Outlook.pst on C drive. I use SyncBack Pro to back it up to D drive nightly. Every night WHS backs up the default Outlook.pst folder on C and the copy in D:\Backups\Outlook bak\. Then using SyncBack Pro I back up the default Outlook.pst folder on C and D:\Backups to PC8B drive Z.
2. MS Word/Documents
Chrome does not use Favorites folder. I don't know where it stores its bookmarks, etc. It is backed up on the Web by Chrome/Google and also by using the synch function of LastPass. The bookmarks and passwords reside on the LastPass server and can be accessed by any browser that has LastPass (if you, have the password). Google has a similar function, but I don't use it.

12. Display Fusion
a. "We've added an automatic settings backup to the installation starting in 3.4.1, so that it would be easy to restore the previous settings in the rare case that they get lost during an update. If you've updated and everything is working as expected, it's safe to delete the Documents\DisplayFusion Backups folder."
b. "Is there a way to get DisplayFusion to automatically backup or store all settings in a specified folder? If I ever have to reinstall windows it's nice to know that all of my settings will already be stored with the rest of my documents (which are, of course, well backed-up)." "By default, DisplayFusion will back up the settings to the "Documents\DisplayFusion Backups" folder any time you update to a new version. There's no way to set regularly scheduled backups, but at least you'll have some recent backups (especially if you run the Beta versions, as we usually update once a week or so).
c. You can do it manually from Display Fusion.
