The two go-to Switch save managers (backup / restore / share) are Checkpoint (FlagBrew) and JKSV (J-D-K). They cover the same category but with opposite design philosophies — pick wrong and your daily workflow becomes a quiet source of friction.
| Item | Checkpoint | JKSV |
|---|---|---|
| UI simplicity | Intuitive | Heavier learning curve |
| Startup speed | ~1 s | ~3-5 s |
| User switching | Yes | Yes |
| File-level selective copy | No | Core feature |
| ZIP compression | No | Yes |
| BIS partition access | No | Yes |
| System saves (news, etc) | No | Yes |
| Custom backup naming templates | No | Yes |
| Direct transfer w/o SD removal | No | Needs FTP separately |
| Cloud upload | No | No |
| Update cadence (2026) | Roughly monthly | Active |
Checkpoint: launch → pick Zelda → L → done. ~5 seconds.
JKSV: launch → pick Zelda → "Backup" menu → name → confirm → done. ~15 seconds.
Checkpoint: can't — operates on whole-save granularity.
JKSV: launch → Splatoon → enter file browser → select system_data.bin only → Copy → restore that file on the other console. JKSV is the only choice when you need file granularity.
Checkpoint: 100 titles × N MB of raw files pile up on SD.
JKSV: enable ZIP and you save 30–50% space. For long-term archive, JKSV.
Both tools fundamentally do the same thing: read raw binaries from the save partition and write them to SD. File format is identical. You can restore a Checkpoint backup via JKSV (and vice-versa), though paths differ so you may need to move files.
/switch/Checkpoint/saves/<TitleID>/<timestamp>//JKSV/<TitleName>/<backup-name>/JKSV uses human-readable title names; Checkpoint uses raw TitleIDs. JKSV wins for opening on PC and recognizing which game is which.
Quick daily backups → Checkpoint.
One button, one second, no friction. If you're trying to build a daily-backup habit, friction is the enemy.
File-level control / system saves / compressed archives → JKSV.
The full-feature option for power users. Past the learning curve, more flexible than Checkpoint.
Both works fine too — disk usage is tiny. Use Checkpoint for daily, JKSV when you need precision.
Checkpoint, JKSV, and our loader all run as homebrew NROs under Atmosphère, sharing the same SD. Either save manager is strongly recommended for loader users — insurance against save corruption or hardware failure.
