I’m the same - I want to Find a good safe but they’re so pricey I keep putting it off as I don’t want to get a crap one. I’ve read that the cheap wallets end up giving people fibreglass splinters so don’t want to cheap out!
I keep some hard drives scattered around (one in my locker at work, one at home). I keep all my documents on there and update regularly. I also have really key documents and photos saved on memory sticks scattered around (car, handbag, grab-bag, Relatives’ house). I’ve also got the documents emailed to myself so I can access them anywhere.
I am a bit worried about security if one of the USBs gets lost/stolen so I’ve been eyeing up some of the ones that are password protected.
As for what documents I have:
Mortgage documents (annual summary)
House insurance
Chimney sweep certificate (required by house insurance)
Qualifications (GCSE, A level, Degree certs)
BUPA cover details
Pension summary (plus Death in service benefit info)
Student Loan statement
P60
Driving licence
Passport
Birth certificate
Car stuff (insurance, MOT/Service docs)
Financial info (not account numbers etc, just who I have accounts/cards with to make it easier to start calling round!
Particularly Sentimental photos (hard drives have them all on there)
I also have a printed copy of passport, driving licence and home insurance in my grab bag.
I tried to think of and cover everything that would be difficult to remember/replace if the originals were lost (wouldn’t be able to tell you which exam board my GCSEs were with for example, this makes it easier to call up AQA or whoever to get a replacement if needed for a job etc)
All this is more for house fire scenario really rather than expecting the apocalypse - I’m fairly sure I won’t give a shit about my French GCSE when the zombies come for me!
