Do you know if Passport has what you mentioned. I went on line looked up manual information and mentioned you could specify the number of backup versions. I kind of scared to change anything. Read the rest of my response after your post I reposted. What external harddrive do you have and are you able to do what you suggested with it?
You may need disable the automatic, continuous backup function before delete those files, othrewise it will keep going backup, backup, and backup. CHeck the manual to see how, even you can uninstall those software too.
What I ended up doing with my full wd external drive was free up space on my Flash drive and since I had no room to delete the last back up
(I think since I saw that last back up failed I manually did it and backup-ed both passport and pc)(that might of been mistake)
I cut last back up and pasted on my Flash drive so now I have 14.5 free space. Now I am going thru my hard drive and deleting documents I scanned and do not need. school stuff and resumes that are old are being put on a flash drive and deleting duplicate photos. Than i am making sure I empty trash bin. So when I do set up my external hard drive it won't backup unnecessary stuff. I am still trying to find information on external hard-drives before I set up the new one. I picked up some computer books but they refer to online backup Backup Exec 9 ever hear of it? Thanks
