Backup in case of device change
If you buy a new device or reinstall your system, you must have a secure copy of your sensitive data. This can be:
An encrypted file on a USB drive
A secure export to a password manager
An offline physical backup
Security best practices
Enable encryption on all your storage devices
Use strong and unique passwords
Never store your seed phrases in plain text
Back up your data in multiple formats (physical + digital)
Final recommendation Immediately delete these files from OneDrive, then migrate them to a secure solution. Do not rely on standard cloud storage for critical data. The security of your digital assets depends on the rigor of your management.
