I want to back up EFS encrypted files in my Windows %USERPROFILE% to an external NTFS formatted USB drive using Windows FileHistory. I have the following problems:
- After clicking "Select Drive" in "advanced settings", and selecting my USB backup drive, a message is displayed on a yellow background, above the box showing the selected drive, saying that "EFS encrypted files were found on a non-NTFS file system or a network location and FileHistory won't backup such files." The only part of this message that is not bogus is that it found some EFS encrypted files. Neither source (C:) nor backup volume were non-NTFS & no network was involved.
- If, you click "Run Now" under the selected, disk drive, you get a message to the effect that "the drive could not be used" & a cryptic error code.
- If instead you close "advanced settings", returning to the main Backup settings screen, and click the "Back up Now" button, FileHistory will spin forever displaying the message "Your files are being backed up for the first time", apparently backing up files, but not actually accessing the backup disk. The USB disk went to sleep due to the lack of activity. I left it for more than 2 hours but FileHistory did nothing except create its folders.
The external USB drive in question is protected with BitLocker and the NTFS volume is in the 3rd partition on the disk. Just mentioning this for completeness. They should not affect FileHistory.
How can I get my files backed up?
Please don't ask why I am not using BitLocker on my C: drive instead of EFS. The answer is not relevant to this question but it is because my C: is a BootCamp partition and Apple says these are not compatible with BitLocker.
