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
recorded in [Backup.dat](System_Settings#extdata "wikilink") and hence
cannot manually be created. For recovery reasons, if
[Backup.dat](System_Settings#extdata "wikilink") 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 restriction is
triggered if a [certain flag](SMDH#byte5b15d "wikilink") in the
title's icon is set. Or if the SaveID of the title is located in the
[ctr_backup_black_list](NS_CFA "wikilink") file in the NS CFA, which is
practically a Unique-ID blacklist. The titles blacklisted in the
[ctr_backup_black_list](NS_CFA "wikilink"), are:
