Back-up  App.'s that work right. ?  (typically used  under MS Windows 10)
The MS version of backup   are/were buggy  and  now wildly odd and complex.  (I never even look there due to getting burned by them for 40 years) "once bitten twice shy" or more.?
I tried EASEUS TODO BACK up , it works good, (poor GUI) but will not install to any non C: boot drive.  (there email support system is lame, English to China language fails hard here and UTC+8 pain !!!)
Criteria of choices in order.
  1. Installs to my F:/program files folder. (if not in  the trash it goes)  It must give me a choice screen 1 first installed .  TODO does not.
  2. It installs ok and does not nag me every day of my life.
  3. Does not install startup files and load up RAM with things I do not want  or need all day long. (with out my PERMISSION ,  Leeloo: Senno ecto gammat!)
  4. The App. running must be user friendly , not chinglish like (GUI) and MUST show clearly source and destinations picked and then warns me at end ,  "you are about to write to X drive" , IS THIS OK?"
  5. It must allow me to restore, 1 file or blocks of files or whole drives, later,  MS loves to fail here , historically.
  6. Not cost $100 for home use, how about $20 (one can only dream in this life)
  7. Now the hitch,  the silly app that only lets you have updates for 1 short year or less, after paying full price. (you suck! and are full of greed)  v12.8 ok, but v13 costs another 100 bucks.
  8. Notwithstanding the seriousness of the  important  nature of your files. (  photos of dog eating bones lost or you  lost files for say QuickBooks  2007 NOT Online:!)  apples and oranges different.
  9. The best choice too is one that has great support and TODO brand does not, no forum at all them and can not answer simple questions. (China support is poor)
  10. Last and not the least the maker supports your  newer version of W10.  (wow old backups work with newer W10?) so that means you must be using top brands APP here. ( not garage or basement built)
To me AMOEI "BACKUPPER" is the best, in all ways, above and Home version is free, if you need the other higher features. They even have a real forum unlike others.
Full Version costs $40 (Jan/2021) and is a life time upgrade    (a 1 year -2PC version for $10.69 total USA)  prices vary from $49 or less, on sale or with coupons. I used Coupons.
If you need a 3 PC license or more ask them first. (most seller of software fail in not having 1 page that tells their rules on Licensing, 1,2,3, PC and if the app goes dead or lame in 1year, or not.

Most will tell me , just use the MS cloud and trust  it. ( I say trust is earned, and that takes years, even 10 years to see that !)

This Page is not SPAM and is only IMHO,  I get not a penny of money for any thing I  print or type or from any clicks ever.
Rule#1
Never ever backup to one driver for sure C: to C: that is crazy.  HDD fail and do so often, I back up to 1 or more External Drives and 2 local servers. After backing up they are tuned off, to extend LIFE !
PITFALLS:
Using BITLOCKER or any kind of built in or added HDD/SSD drive encryption can fail so easy it is not even funny, (don't) Or buy high end, products to do that and pay through the nose.
Source of target Drives are bad or fails SMART TESTS.

Note the clear wording here,  and the cute arrow, too, making any user confident the APP is doing what you want !!!  1,2,3, add folder (source) #2, pick target and last #3 start backup.

version 1.  1-1-2021 (100% only my limited opinions. )
