For the past year I've had the server setup to backup the OS drive only on to a Seagate 250GB drive, once a day. The disk space used has grown to 155GB out of a useable 238GB. I bought a WD Elements USB 3.0 500GB drive to use as the server backup drive. Ran the Customize server backup utility from the dashboard, selected the new external drive, unselected the old drive.
After all is said and done, WHS2011 assigned a drive letter to the old server backup drive, so now it shows in my computer. I'm confused on where the space on this drive is used? When I look at the properties of the drive, it says 155 GB used, but when I look to see what's on the drive, there is a windows image folder (much the same as if I would run backup from a windows 7 PC), and only 22GB worth of files are inside. Where is the other 133GB worth of files? Folder properties are to show hidden files, yet there doesn't appear to be any.
I ran a new backup after setting up the new external drive and the backup size it 22GB, which is what the dashboard now says is the space used on the new server backup drive.
When I go to the windows server backup program, it tells me there are roughly 391 copies between my old drive, the one copy on the new drive and a couple I had run from this program to external drives for safe keeping. When I look at the copies, the date goes back to July of last year. From the dashboard, I can select the server and view the backups, it goes back to June of this year.
Should I just start from new with this external drive, or is there a need to keep those backups and phantom files from the old drive? What are those 'phantom files' and how do I know they are even there? (talking about the 133GB worth of used up space on the old backup drive that I can't see)
