I have a HP Simple Save external hard drive 1 TB which saved all of the files from my old HP desktop computer which was old an giving me problems suggesting it might crash and burn so I bought a new HP ProDesk 400. Both desk tops had Windows 7 64 bit OS. I am not a computer savvy person. The Simple Save external hard drive had about 410 GB of data from my old computer on it and about 590 GB of space left on it.
My computer person transferred all of my files from my old desktop to the new desktop. I have used my new HP desktop for about a week before I realized I need to back up new files on it.
I was hoping that I could just plug the HP Simple Save into my new desktop and it would pick up copying only new files from the past week, not the old files it already had saved from my old desktop. However when I ran the back up today on 12/4, an error message came up which said the following: The last back-up did not complete successfully. I then saw that there is only 87 GB of free space left on the Simple Save and that under today's back-up about 262 GB was used to create a system image and 171 GB went to backup of data.
So my take on this is that the Simple Save did not pick up where it left off from my old desktop and that it is recognizing the new desktop as a separate computer which it is (I was hoping it had the ability to recognize files as already saved and skip them and only copy new files.
1) Am I correct that Simple Save cannot recognize files as already saved if they are coming from two different desk tops?
2) I do not want to lose any of my files saved from the old desktop computer to the Simple Save just in case there may have been some glitches in the transfer of my files from my old desktop to my new desktop. If I delete everything (System Image and Data File Backup) saved on the Simple Save with a date of 12/4 (today when I tried to back up the new desktop) will I retain all of my data from the old computer?
3) What is the purpose of creating a system image of the new desktop which took up 212 GB today. Should I retain it?
4) Is there a way to delete the data files copied today (171 GB) which likely is mostly duplication of files already on the Simple Save and get the Simple Save to only recognized new files from the past week?
