An inventory that burns with the house it documents has done nothing except waste an evening. Storage is not an afterthought here; it is half the exercise.
The rule, in one line
Three copies, two kinds of media, one of them off-site. It is the old backup rule and it fits this problem exactly.
Ranked options
| Location | Survives fire | Survives theft | Reachable during evacuation | Notes |
|---|---|---|---|---|
| Computer in the house | No | No | No | The working copy, not a backup |
| USB drive in a desk drawer | No | No | No | Same building, same risks |
| USB drive at a relative's house | Yes | Yes | With a phone call | Cheap and effective |
| Bank safe deposit box | Yes | Yes | Only in banking hours | Good for appraisals and deeds |
| Fireproof home safe | Partly | Partly | Yes | Rated for paper, not always for electronics |
| Cloud account you control | Yes | Yes | Yes, if you have credentials | Encrypt before uploading |
| Email to yourself | Yes | Yes | Yes | Crude, works, size-limited |
On fireproof safes and electronics
Consumer fire safes are commonly rated to keep paper below its ignition point. Flash drives, SSDs and optical media fail at much lower temperatures than paper does, so a standard fire rating does not imply the USB stick inside will be readable. Media-rated safes exist and cost more. Paper printouts of the summary report, on the other hand, survive a fire safe well — which is a reasonable use for one.
Encrypt the off-site copy
A drive at a relative's house is a physical object that can be lost or borrowed. Encrypting it means the inventory of your valuables does not become a shopping list for anyone who picks it up. Windows offers BitLocker To Go; any reputable archive tool with AES encryption also works. Write the password down and keep it somewhere unrelated to the drive — a password on a sticky note attached to the drive is theatre.
If you use cloud storage
Use an account you control and upload an encrypted archive rather than loose photos. The point is not paranoia about the provider; it is that a folder named "home inventory" full of photographs of valuables, shared or synced accidentally, is a genuinely bad outcome.

Refresh on a schedule that exists
A backup made once, two years ago, is a backup of a house that has changed. Tie the refresh to something you already do:
- When you update the inventory after a major purchase, copy the file to the drive.
- Twice a year — daylight saving changes are a common anchor — swap the off-site drive.
- After any renovation or move.
What to include in the off-site package
While you are doing this, the same drive should carry the documents that are painful to replace: policy declarations pages, appraisals, deeds and titles, vehicle registrations, birth certificates, passports scan, medical and prescription lists, contact details for your agent and adjuster. The inventory is the bulky part; the rest costs nothing extra to include and turns a backup into a genuine emergency kit.
