I have read all the user manual material but cannot find an answer. I have a passport prtaable drive that I use to back up my Windows laptop,
I am using the WD sofware that came with it. When I did the first back up, I set it to backup all types of files and I assume it backed up the entire HD of my laptop.
My question deals with subsequent backups. Do subsequent backups only create a backup up of each specific file that has been modified since the previous backup OR just do an entire backup of all files, changed or not, once again.
If i set it to maintain 3 copies, depending on above answer, does it then keep the last 3 copies of only the modified files or 3 copies of the entire laptop.
Again I am using the backup all files setting for each backup.
If it backs up the entire source every time, is there a way to only bacup modified files?
