Windows 10: Encrypting File System EFS BackUp question

Before you encrypt anything important,
A.you should back up your file recovery certificate and your
B.personal encryption certificate with their associated private keys,
C.as well as the data recovery agent certificate to a USB flash drive UFD.
Store the UFD in a secure location.
If you lose the certificate stored on your hard drive because of a disk failure, for example
you can restore the backup copy and regain access to your files.
My question is.

1.Should i encrypt the BackUp with EFS ?

2.Should i store the BackUp as a single file or can i save it in a folder example EFS BackUp

Grateful if any from Microsoft can answer my questions.

:)

Backup the EFS encryption key file

Yesterday I installed OneDrive app and linked it to my office 365 enterprise University account. Since then, every time I turn on my pc, I receive a warning about backup of the encryption key from EFS application. But I have never used bitlocker.
I did some search online and I got the list of all encrypted files: there are thousands of files and belongs to Apps, like facebook, onedrive, inkscape and so on.
So my questions are:

• why did that message suddenly appear?
• why are those files encrypted?
• do those files have to be encrypted?
• bitdefender has just found Gen:L: [email protected]@bq2Abpn in temp folder. Could I have got a ransomware that is encrypting all files?

Thanks in advance!

 

Backup the EFS encryption key file

Bitlocker and EFS are not the same thing. Bitlocker is full-disk encryption; EFS is per-file encryption.

I agree that it's probably some IT policy from your university account. You should backup your key: Backup Encrypting File System Certificate and Key in Windows 10 Security System Tutorials
