SD Savedata Backups

Revision as of 08:18, 13 September 2013 by Yellows8 (talk | contribs)

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, restrictions.

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> - 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.

Restrictions

Some titles are restricted in how their saves are backed up. These restricted saves can can only be backed up when the title is deleted and can only be restored once. GBA titles however are not allowed to be backed up at all, the reasons for this are unknown. This is enforced by the ctr_backup_black_list file in the NS CFA, which contains a list of blacklisted Unique-IDs:
