How do You Backup Your Garmin to the PC?

I was going to use Allway Sync which is a great program that provides synchronized updates. ie The file is not updated if there have been no change.
However on my nuvi 750 2303 of the 2475 files have no date. And of course file date/time are one of the criteria used for determining that the files need to be copied. So as a result Allway Sync thinks 2303 files need to be updated.
And the 1GB img file on the 750 is one of those with no date.
So just wondering what you do.
robocopy
Gary A, no doubt SyncBack will work well for the GPSr backup but I like using robocopy because I used to use xcopy a lot and robocopy is similar but much more versatile.
robocopy comes with Windows Vista and Windows 7. It is a free download for XP.
It is very easy to use for the subject task of backing up a GPSr drive.
Say the GPSr drive is f: and the backup drive is g: (could be flash drive or SD card) or you could use c: for your computer's hard drive.
The command to give would be:
robocopy f:\ “g:\Garmin 255W BU” /e
[Note: the quotation marks must be used as shown if spaces are used in the destination folder name]
That command would copy all the files and folders from the root of the GPSr drive to a folder named “Garmin 255W BU” and will automatically copy any hidden files.
Later, if files have been added or changed on the GPSr, you can issue exactly the same command again and only the new and/or changed files will be copied to the existing backup folder.
The command can be run in a “cmd” window or you can put it in a batch file and run it that way.
.
As was mentioned, there can be hidden/system files on certain units. When making a backup, be sure the PC is configured to show hidden/system files or they won't get copied over. A backup done this way will be able to restore normally accessible files on the unit.
One thing to note is that backing up all the files on the unit will NOT backup the flashed firmware. This is in a separate memory location which is not accessible to the user. In other words, if you're looking to restore a bricked unit due to a bad firmware flash or firmware memory corruption, your backup of the files on the unit will be useless.

system files

I had not been thinking about system files when I as describing robocopy because my 255W does not have any system files on it.
robocopy will automatically copy hidden and system files no matter whether the PC is configured to view them or not.
Cannot copy file: Cannot
Cannot copy file: Cannot read from the source file or disk
I have tried to copy the entire contents of my Nuvi 205 to the hard drive of my PC, but I get the above message on *some* folders. It's odd because I can copy some folders over, but then that error message will show up on others. Did anyone else face this problem?
Question on use of switches in bat file for backup
Its been about 5 years since I new the swtiches well so could you help me figure out the function of the switches you used?
"--/s/r/y/c/d/k" Z:\NuviBackup
If you modify the script what is it now and what is the improvement?
Thank you for explaining your switch usage.
