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

 

Windows 10 Encryption/Decryption of Folders/Files 'Certificate'

Hi,

Thank you for posting in Microsoft Community.

To understand the issue better, I suggest you to answer the below question.

• Were you able to Encrypt the data?
• Did you get any error message?
• What exact issue are you facing with Encryption and Decryption?

Note: The first time you encrypt a folder or file, an encryption certificate is automatically created. You should back up your encryption certificate.
If your certificate and key are lost or damaged and you don't have a backup,
you won't be able to use the files that you have encrypted.

Keep us posted to help you better.

 

Backup the EFS encryption key file

My IT support staff told me that it doesn't depend on them. So why did those message start to appear?
Anyway, do you think I should make a copy of certificates on a external storage or try to decrypt all files?
