What JKSV is

JKSV is a free Nintendo Switch homebrew save manager for backing up and restoring game save data. It works with saves for user accounts and other supported data types, including system, BCAT, device or shared, temporary, cache, and system BCAT saves. Backups can be exported as unpacked folders or ZIP files; ZIP is required for cloud backup. You can back up every save on the system or all saves for one user in a single operation.

With cloud backup configured, JKSV supports Google Drive and WebDAV, and automatic uploads are available. Google Drive setup requires your own Google Cloud project and OAuth client; WebDAV requires a configured server, either hosted by a provider or on a local network. JKSV can create save data for titles on the system without launching them. It can also import or create save data for titles not installed on the system, though the maker warns that these saves are not properly installed. Other tools include extending save size, viewing basic save and title statistics, and deleting saves. Safety options can require holding a button to complete destructive actions or create a backup automatically before restoring. The project provides a Nintendo Switch homebrew build and is licensed under GPL-3.0.
