How do you check that your Litecoin wallet backup actually works?

Two threads here this week were about old Litecoin Core wallets. One person couldn’t find their passphrase, and another has a 2018 wallet file that makes Core close during sync. Both had kept backups, but hadn’t looked at them in years.

It made me curious how people here handle this:

  • Do you ever test your wallet backup, for example on a spare device with a small amount?
  • If you use Litecoin Core, where do you keep the wallet file and the passphrase, and are they stored separately?
  • If you’ve switched wallets over the years, do you keep a note of which backup belongs to which wallet? In one of those threads, a 12-word phrase turned out to be from a different wallet entirely.

From the support side, mixing up which backup goes with which wallet causes a lot of stress, so I’d like to hear what habits work for you.
