You can backup (backup is used here as a generic term) the contents of the B2’s Hard Disk to a USB memory stick/flash drive or a portable USB HDD - either device will need to be formatted with FAT32 to work with the B2 - the B2 can do this - see 'Formatting the USB device'.
It is also possible to backup to a computer over your LAN using the B2’s NAS mode - see 'Backing up with NAS' section.
Export to C: B2 owners not needing the backup to be JB7 compatible should use this. Running 'Export to C' generates a B2 backup file called B2Export - this folder contains a ‘music’ folder and a ‘playlist’ folder.
Backup to C: For JB7 and B2 owners who need the backup to be compatible between both machines. This generates a backup file called ‘hardfi’ and a ‘playlist’ folder.
With the B2 powered off > plug the USB device into USB C (or USB A) > power on > using the front panel control go to - Settings > Maintenance > Format USB C.
‘Partitioning’ will be displayed briefly and then ‘Formatting’ for around 30s to 1 or 2 minutes (depending on the device’s memory size) - any quicker than this indicates that the format hasn't worked, so run it again. Please note formatting will erase all data on the memory stick/HDD. When completed the display will return to the Home screen (the one displaying the clock).
FAT32 will work with a maximum memory size of 2TB.
