I am using Windows 10 and Windows 8.1 and have File History and Windows Backup enabled to store backups to a shared NAS folder regularly.

Since I am concerned about ransomware trojans, I want to make sure, that an infected system cannot affect my backup files.

My plan is

  1. restrict access to the shared NAS folder to a special backup account
  2. configure the backup software to use this account (without exposing the credentials)

Is this possible?

EDIT: this question discusses other/better ways to achieve security, but does not address running backup software with restricted accounts.

  • The only way to protect yourself from ransomware encrypting your backups is for those backups not to be connected to your pc or network at the time of the infection.

    @CharlieRB yes, that is very helpful, thanks. I still keep my question open, since I am particularly interested in the account configuration

  • @Ramhound why would you say that a connected, but inaccessible drive would be insecure?
