Backup
From Obyte Wiki
See Recover page for recovering from seed.
This article is about backing up your wallet using the Main Menu items:
Full backup: Lets you set a password (don't forget it!) and export a full backup file. You should do a full backup every time you do a blackbytes transaction. Many people have lost funds because they didn't do a backup.
Restore from full backup: Note this will permanently delete all your existing wallets and replace them with whatever is in your backup file. If you created this backup on another device, you should have stopped using the original device platform immediately after creating the backup. Never clone platforms/wallets. If you must access your funds from several devices, use multisig.
