What is stored on microSD backup card? Can I copy card content?

Modified on Mon, 06 Jan 2020 at 01:22 PM

Your microSD card that is used as a backup card in BC Vault is formatted in standard FAT16/FAT32 filesystem. Each backup is written as a file and you can decode following information from the filename itself:





Backup was made on 05th January 2020.


Backup was made at 12:45:24 o'clock.


Base58 encoded backup name. You can decode that with any Base58 decoder (Example of online version). In this case the name is "My first backup".

You can simply copy the backup files and store them on additional places (Remember: All backups are still fully encrypted with your Global PIN+Password and all Wallet PIN+Password). When you need to restore, copy them back to microSD card and use the Restore function in the application.
