Does anyone know how to purge deleted files (on the backup source) from a WD My Passport that also contains additional data using WD SmartWare?

I guess you can delete the files from the disk one by one on the backup, but thats not what I'm looking for as it would not be viable solution after deleting e.g. hundreds of images on the source.

Edit: As @Ramhound pointed out below, the easy solution is to use another solution than WD SmartWare. I'm however keeping the question up so that other with same problem can find this information, or WD SmartWare gets better.

[Edit] It seems not all files need to be deleted. Just ones missing from the source.

Deleted previous answer (which was use format to delete/purge all files)

Desktop:                          Backup folder on external drive:
file1.png                         file1.png
fill2.png                         file2.png  

rsync with the --delete flag will:

  • Copy the new files (efile3.png in this example)
  • Check other files for changes (if file1.png or file2.png have been changes the newer version from the desktop will be copied. If unchanged no copy takes place)
  • Due to the --delete flag the file old_picture.png will be deleted.

I asked for a way to purge the deleted files and not format the disk. I'm backing up a slow usb 2 machine and doing a re-backup of gigabites with image/video after a cleanup is not viable. – grm Nov 27 '12 at 13:00
@grm - Why don't you just delete the files? – Ramhound Nov 27 '12 at 13:04
In that case, I do not get it. You made a backup to an external drive. That drive has your backup files (and I assume only that). You want to purge/delete all files from the drive. But not with format? Then what do you precisely want? – Hennes Nov 27 '12 at 13:05
@Ramhound from the passport? Imagine editing hundred of images on your source then manually deleting the same files on the backup media? Hopeless! – grm Nov 27 '12 at 13:07
Ah. Now it makes sense. Which OS? If unix like check out rsync --delete. – Hennes Nov 27 '12 at 13:11
