Cannot backup EFS encrypted files

Hi,

from what I read in the forum, this problem has been discussed, solved (by program update) and re-introduced (by software bugs in follow-up versions) some times already. Now, with TI 2014, it's back:

I cannot backup EFS encrypted files in a file based backup. The error is: "Backup of file or directory xxxx failed". German original message:

Backup von Datei oder Verzeichnis 'D:\TMP\Test.txt' fehlgeschlagen.
Fehler beim Backup. (0x40019)
Tag = 0xCE542E14DA203AC3
Zugriff auf die Datei oder den Ordner wurde verweigert. (0x40014)
function = "CreateFileW",
filename = "\\?\D:\TMP\Test.txt"
Tag = 0xA8A1022BD18AE01B
Zugriff verweigert (0xFFF0)
code = 80070005)
Tag = 0xBD28FDBD64EDB8C3: Kein(e)

It's an "access denied" error.

Some solutions propose to store encrypted files unencrypted in the backup (change backup settings accordingly), but that is not an option for me. I encrypt my files for a reason, and I expect them to stay encrypted. Also, I found some forum posts mentioning that this problem has already been solved in earlier versions but re-introduced again with newer versions of TI.

One solution is to perform the update as another user (by changing the backup settings and entering another account) which has the appropriate certificate imported. Normally the backup runs under the SYSTEM account, but I did not find a possibility to import an EFS certificate to that account. The pfx file can be exported from current user and imported to another account, but not to the SYSTEM account for all I know. Does anybody know a way to achieve that? In the task manager I see that the process TrueImageHomeService.exe runs under the account that is specified in the backup settings, or SYSTEM if none specified.

Or, even better: can this bug please be fixed again, and permanently?

Many thanks.
