Overview
Introduced in 6.0.0-11, users are able to backup savedata for titles installed to SDMC, to a maximum of 30 'slots'. Users can backup savedata while in the Home Menu, available as an option when selecting an application. In System Settings, user are able to backup, restore and delete savedata backups. There are however exclusions, see Exclusions.
Backups
Savedata backups are located in the directory:
sdmc:/Nintendo 3DS/<ID0>/<ID1>/backups
The savedata backup directory structure(this structure is repeated for every slot):
backups
└───XXX
└───<Application TitleID>
- XXX - A three digit hexadecimal number representing the slot number i.e. (000-01d).
- <Application TitleID> - The application's full TitleID. This directory contains a verbatim backup of files in the title's "data" directory(where the save file is located).
There can only be one savedata per slot, and details about the slots are stored in System Settings's Extdata and hence cannot manually be created. For recovery reasons, if the System Settings's Extdata is damaged, details about the backup slots will be recreated from the files in the backup directory.
Exclusions
Some titles are not allowed to have their saves backed up. (This restriction only applies to the backing up of saves) This is enforced by the ctr_backup_black_list file in the NS CFA, which contains a list of blacklisted Unique-IDs:
