JKSV

JKSV is a Nintendo Switch homebrew save manager for backing up and restoring game save data. It supports saves tied to accounts, the system, BCAT, devices or shared data, temporary data, cache and system BCAT. Backups can be exported as unpacked folders or ZIP files; ZIP is needed for cloud backup. Users can back up all save data on the system or all data for one user in a single operation. With cloud backup configured, JKSV supports Google Drive and WebDAV, including automatic uploads. Google Drive setup requires users to create a Google Cloud project and OAuth client, while WebDAV needs a configured server from a provider or hosted locally. Other tools include creating saves for installed titles without launching them, resizing saves, viewing basic save and title statistics, and deleting saves. JKSV can also import or create saves for titles not installed, though the maker warns these saves are not properly installed. Safety options can require holding a button for destructive actions or back up data automatically before a restore. The Nintendo Switch homebrew project is free and identifies its license as GPL-3.0.

JKSV offers broad save backup and restore options, including configured cloud uploads. Cloud use takes extra setup, and the maker cautions against treating saves for uninstalled titles as properly installed.

JKSV is for Nintendo Switch users who want to manage local save backups or configure Google Drive or WebDAV backups. It assumes comfort with the setup steps for those cloud services.

JKSV is a Nintendo Switch homebrew save manager for backing up, restoring and organizing a wide range of save data. It suits Switch owners who want bulk protection, specialized save tools and the option to automate uploads to their own cloud storage. Its strongest case is comprehensive local control; its main drawback is that cloud configuration requires technical preparation.

Overview

JKSV covers more than ordinary game-account saves. It works with account, system, BCAT, device/shared, temporary, cache and system BCAT data, giving experienced users a way to protect console data that simpler utilities may ignore. Automatic game detection helps locate titles, while restores are manual, so the workflow favors deliberate control over unattended recovery.

The project is the Switch Edition of JK’s Save Manager and is distributed as a Nintendo Switch homebrew build under the GPL-3.0 license. The latest release is dated 12/02/2025. The maker welcomes bug reports and accepts optional donations, but the software itself costs nothing.

Key features

JKSV can back up or restore supported data for Switch users, and it can capture every save on the system or every save belonging to one user in a single operation. That makes it practical for a broad safety copy before moving between consoles or experimenting with a title, rather than requiring repetitive game-by-game work.

Exports are available as unpacked folders or ZIP archives. ZIP is mandatory for cloud backup, an important distinction for users who prefer transparent folder-based archives locally. Configured Google Drive and WebDAV integrations support automatic uploads, but neither behaves like a one-click consumer sync service. Google Drive requires creating a Google Cloud project and OAuth client, using Google’s limited-input device login flow. WebDAV requires a provider-hosted service or a server you operate on your local network.

JKSV can create save data for an installed title without launching the game. SVI support can import or create data for titles absent from the system, but the maker cautions that such saves are not properly installed. Treat that function as a preparation or transfer aid, not as a guarantee of a usable save for an uninstalled game.

Additional tools include resizing a save to a chosen size, which can help with games such as Minecraft, plus basic save and title statistics and cleanup tools for deleting saves. Safety options are unusually useful for a utility that can erase or overwrite data: destructive actions can require a button hold, and restores can trigger an automatic backup first.

Pricing

There is no paid tier, trial period, seat limit or subscription renewal. Both entries describe the same free software, so readers do not trade features for a cheaper plan; the practical choice is simply whether cloud functions matter to their setup.

Platforms

JKSV targets Nintendo Switch homebrew installations. It is not presented as a Windows, macOS, Linux, Android or console-agnostic save manager, so choose it specifically for Switch use and a compatible homebrew environment.

Who it's for

JKSV is a strong fit for technically confident Switch owners who want whole-system or per-user backups, support for uncommon save categories, and automatic uploads to Google Drive or WebDAV they control. It also suits users who need save resizing, SVI handling or cautious restore procedures.

It is a weaker choice for anyone seeking a conventional desktop application, a guided cloud service, or fully automatic restoration. Drive and WebDAV setup involves external infrastructure, cloud uploads require ZIP archives, and restores remain manual. SVI handling also demands care when the target title is not installed.

Pros and cons

Pros

• Broad save-type coverage protects account, system, BCAT, shared and temporary data alongside ordinary saves.
• Bulk backup can capture the entire console or one user in one operation, reducing repetitive work.
• Automatic uploads to configured Google Drive or WebDAV add an off-device copy.
• Button-hold confirmation and pre-restore backups reduce the chance of an irreversible mistake.
• Save resizing, statistics, cleanup and save creation provide useful maintenance tools beyond simple export.

Cons

• Cloud use requires a Google Cloud/OAuth setup or a WebDAV server, which is a substantial barrier for casual users.
• Cloud backups must be ZIP files, limiting format choice for upload workflows.
• Restoration is manual, so recovery still needs user intervention.
• Saves created for uninstalled titles are not properly installed, limiting SVI’s practical use.
• Switch homebrew support excludes users who need cross-platform save management.

Alternatives

For a broader comparison, see Game Save Managers.

• SaveState is the better pick for Android, Linux, macOS or Windows users who want local backups with optional cloud sync and no account.
• OmniSave suits users seeking a free manager on Android, macOS or Windows instead of Switch homebrew.
• Gamekeeper fits Windows users who need multiple storage protocols, including FTP, SFTP, WebDAV, SMB/CIFS and S3.
• Playnite Save Manager is appropriate for a Windows Playnite setup; its cloud sync is experimental.
• QSave is a free, open-source macOS or Windows option that sends saves to your own Google Drive.
• Save Keeper targets PS Vita or PS TV systems using HENkaku or h-encore, with a Google account required for Drive sync.
• SideSave is a free, self-hosted or Linux-oriented alternative built from source.
• Checkpoint64 is a freemium Linux, macOS and Windows choice with team-oriented storage limits and paid expansion.

Verdict

Choose JKSV if you own a homebrew-capable Nintendo Switch and want unusually broad save coverage, bulk backups and the flexibility to route ZIP archives to Google Drive or WebDAV. Look elsewhere if you want cross-platform support, turnkey cloud syncing or automatic restores; JKSV rewards technical control, but it does not hide the work involved.
