Two is one, one is none. Backup items are a related topic.
A good heuristic for the first things you should buy backups for is the things that if they broke / got lost / were stolen, would be most disruptive to your life while you procure a new one. Some ideas:
Phone, laptop (so just keep your older ones around)
And when you travel, duplicate debit cards! I just opened a second free checking account at my bank to do this. Keep one in your carry-on/hotel room, and one when you go out on excursions. So if you get pick pocketed or the ATM refuses to return your card, you have a spare.
This also lets you use cash for all your transactions—so the only way you can be skimmed is at the ATM, nowhere else.

Eyeglasses
Chargers
Medications
Keys, IDs, important documents
Duplicate IDs are hard to come by. However, you might be able to have multiple different forms of ID (such as an ID card and a passport).
Backup citizenship! There were some posts about it here I think.
