Hello,

I currently try to backup some files which are encrypted with EFS.

The profile was executed by an user which are in these group :
- Domain Admin
- Backup Operators
- Administrator

I have a lot of errors : Access is denied.] [ERROR].

My profil settings :

Comparison
- Comparison Type: Size and Timestamp
- Ignore 2 seconds difference
Execution
- Method: Backup (Mirror Source to Target)
- No overwrite / read-only / error confirmations
- Log only summary and errors
- No archive for deleted/replaced source files
- Archive deleted/replaced target files to: "\\?\R:\_Archives\"
- Smart archive
- Append Source/Target path to archive folder(s)
- Network friendly folder scanning
- Copy file/folder permissions
- Replace newer target files with older source files (backup only)
- Send customized e-mail


Any ideas ?

Thanks

Yes, I have "access is denied" only on files which are encrypted.

I tried with a profile where I backup only one encrypted file with EFS and I always have the error

Do you think, it's possible in a next edition to add the robocopy option ?

I have, for the moment, errors which are solve by robocopy and if we use it and not "copy" or "xcopy" we havent the error into cmd.

Hi,

When I use /efsraw i can copy all encrypted file.

Here an example :

Set PARAMS=/efsraw /ZB /R:1 /W:5 /nfl /ndl /TEE
Robocopy \\serveur-donnees\e$\Users\tests\ E:\Synchros\Test\ %PARAMS%

The encrypted file was copied into the destination directory.

ViceVersa backs up the file by copying it not encrypted, that is, it decrypts the file and then copies it... I think the Robocopy parm keeps the file encrypted. Probably access is denied to ViceVersa because the account running ViceVersa does not have the authority to decrypt the file, is this the case? thanks

robocopy copy the file in raw, it don't touch the file by decrypted it.

Yes, the user was not allow to read the file because is not an agent allow to do that.

Hello,

Thank you for you update,

The EFS support is good, but only when user can read the file.

Is it possible to do like robocopy ? Robocopy copy the file by raw, it don't try to open the file.

Thank you in advance

Hello, we have some prototype source code that can copy EFS RAW files (the same functionality as with the Robocopy option /efsraw)
The main reason we have not released this functionality is: how do you restore a raw file for RAW to encrypted again?
