What JKSV is
JKSV is a Nintendo Switch homebrew save manager for backing up and restoring account, system, BCAT, device or shared, temporary, cache, and system BCAT save data. It can save all data on the system or all saves for one user at a time, exporting backups as unpacked folders or ZIP files. ZIP is required for cloud backup. After configuration, JKSV can upload backups automatically to Google Drive or WebDAV. It can also create saves for titles on the system without launching them, import or create saves for titles not installed, and extend save data to a chosen size. The maker warns that saves for titles not installed are not properly installed. Other tools include basic save and title statistics and cleanup for deleting saves. Safety options can require a button hold before destructive operations or make a backup before restoring. Google Drive requires users to configure a Google Cloud project and OAuth client; WebDAV needs a configured server. JKSV is free and licensed under GPL-3.0.

Who it suits
JKSV suits Nintendo Switch homebrew users who want to manage and back up saves locally or to configured cloud storage. Users seeking cloud backups need to set up Google Drive credentials or a WebDAV server.
Verdict
JKSV brings broad save management and optional cloud backup to Nintendo Switch homebrew. Its cloud features require setup, and imported saves for titles not installed come with a maker warning.
