I think the Hubbers commmunity needs to request and receive a clear answer from HP about their backup procedures, safeguards, etc. I suggest we all make a concerted effort to ask and get that answer.
Personally, I write everything in word like many other hubbers and then cut and paste. But that doesn't mean there is a copy of the entire hub -- pictures amazon, ebay capsules etc., which would be helpful of course. As we are talking about backups...I know there are lots of ways to do this. What has been most successful for me and gives me great peace of mind is using "Carbonite" (no I do not work for them).
I am a professor and I write on HP, so I have untold numbers of files and folders - 15 years worth of lectures, reports, syllabi, committee proposals, prose, poetry, correspondence, hub research, hubs in progress, etc. Losing it all would be an economic as well as a personal disaster.
For about sixty dollars a year, five dollars a month, Carbonite backs up my entire computer (music and pictures files as well) and stores everything on a secure site. They monitor and continue to back up new files or new material added to older files whenever your computer is on.
Backed up files appear with a tiny green dot up in the corner, ones in process of being backed up have a tiny yellow dot. And yes two years ago my computer suddenly crashed and I lost everything. New computer, called Carbonite, and they restores ALL my files. Not everything was in the right folder or organized exactly how I wanted, but restoring my personal organizational system took maybe eight hours total. Carbonite is so worth it to me.
