Custom commands purged for inactive account

Hi, it's been about 2.5 years since I last streamed, and I'm looking at starting up again. I understand that nightbot purges custom commands for inactive accounts, which would include mine, and that's reasonable. My question is whether there's any chance of retrieving the commands from an old backup or something for my account? (account name "BingsF")
If that is not possible I understand, cheers 💚
