Wow. I navigated away twice and lost all my typed reply .... twice. The 2nd time I just hopped into a different tab window, and blank greeted on return to this tab.
Ugh.
I used Vista Ultimate and Win7 Ultimate. These have Image Backup and File Backup options. I manually schedule Image Backup and schedule automatic daily File Backup. Both variations do incremental adds.
I understand Windows versions below Professional and Ultimate levels might not have the Image Backup option.
Both types of backup folders are subject to Windows User Account Control. So even though my User login has Administrator rights, when I double click on them, it says "no entry."
I know I had / have difficulties there, but I may have found some process to tweak it online, because, I now just double click it a 2nd time and it allows me enter, rename, etc. I do not remember what steps, if any, I did to otherwise facilitate this.
If you are having difficulty with Windows infamous User Account Control, I did come across something recently that may help you.
PC Magazine has an utility called RAAC (Run As Administrator Controller). They charge $8 for ad hoc downloads, but if you pay for annual $20 subscription fee, you have free downloads from much of their very interesting, useful library. Just search for RAAC PC Magazine. Maybe it will help you,... if not for this particular problem, then maybe for other difficulties with UAC that may arise.
Cheers and good luck.
