Quicken has an inventory module that can do everything you ask.
- Export to DVD
- Smal jpeg images are attached by 'room' of 'closet' or piece of furniture
- Cloud backup or other backup just like your image files
I took a photo of each side of each room, then entered every item in every photo in the Quicken module
Open a closet, take a photo, enter the items. They don't need to see every item; just that your claimed inventory is credible.
Open a drawer, take a photo, enter the items
Anything with a serial, enter the serials and shoot the serials (drawer full of lenses with covers off)
Open the silver cabinet, shoot it, count the forks, enter in Quicken. Same with China.
CD's, books and DVD's, shoot them and count them. What they are doesn't matter.
Separately photograph jewelry pieces and valuable watches, electronics (incl. Serial plates), tools, etc. scan any jewelry appraisals and save off-site.
Don't forget the garage.
Don't forget the basement.
Scan any receipts you still have and add to the proper room section
It will take a long time. Do a room a week, or every couple days.
When you add things up you will find the contents of your home is 10x what your insurance coverage says it is
