I use a WD Elements 3 TB External HD for doing system backups, and for saving copies of my photography. While downloading photos onto my Hard drive, I also save them onto the WD. I just got a message that the backups did not load; looked to see, and sure enough, the WD Elements is full! But when I got to looking to see what it is full of, I find that mostly it is full of Data FIles that have been backed up. It shows thatI have 2.22 TB tied-up in data file backups. I would like to free up space by deleting the oldest backup, which is 1.23 TB in size. IS THIS SAFE?
Here is what it shows for date file backups:
11/11/2013 to 2/9/2014 1.23 TB
2/23/2014 to 4/20/2014 716.06 GB
5/4/2014 to 5/18/2014 302.76 GB
It looks to me like it is saving the backups cumulatively. Do I risk losing data if I delete the 1.23 TB backup? Thank you for any help with this issue! I just need to be sure before I hit the delete button.
