About Synctoy

Error message:

Lately, I would like to back up my whole Drive D:/, which mostly stored my own data, with synctoy 2.1.
Unfortunately, I got the error message "Cannot read from the source file System Volume Information\. Access is denied. (Exception from HRESULT:0x80070005 (E_ACCESSDENIED)". If I check the following 2 options, then this error will not more exists.

Exclude hidden files
Exclude system files

Another method :

1. Select the D: backup operation
2. Click Change Options
3. Click Select Subfolder
4. Uncheck "System Volume Information" and the recycle bin (RECYCLER or $RECYCLE.BIN) on both sides

I also find it helps to run a drive backup operation elevated ("run as administrator") if you are on Vista or 7, or XP as a standard user.

Folder pair:

SyncToy(2.1.0.0) stores the folder pair info in the

'C:\Documents and Settings\%USERNAME%\Local Settings\Application Data\Microsoft\SyncToy\2.0'

location for each user.

Before using Synctoycmd.exe:

You have to sync through SyncToy one time before using SyncToyCMD.
However, you should see an error in the SyncToyLog.log file.

Annoying Command window:

To avoid the taskeng.exe window from popping up ever time the scheduler runs SyncToyCmd,
users can create the following script in notepad and then saved is as SyncToy.vbs and then get Task Scheduler to run that instead:

‘ SyncToy Scheduler
Set WshShell = WScript.CreateObject(“WScript.Shell”)
WshShell.Run “”"C:Program FilesSyncToy 2.1SyncToyCmd.exe”" -R” ,7

The ‘,7′ will start the taskeng.exe window minimised, to hide the window completely it can be changed to ‘,0′

Log file location:

The SyncToy log can be viewed by choosing the View Log option from the SyncToy File menu.
The View Log dialog also has an option for deleting the current log contents.
The log file is placed under the user's local application data folder
(on Windows Vista: %LOCALAPPDATA%\Microsoft\SyncToy\2.0\SyncToyLog.log,
on Windows XP: "%USERPROFILE%\Local Settings\Application Data\Microsoft\SyncToy\2.0\SyncToyLog.log")
