Where Does Sailfish OS Store System and User Data?
Where Sailfish OS keeps system and user data on phones, plus backup roles explained. Exact folders are covered below.
Last updated
Sailfish pairs its own gesture UI with Android app support underneath. The phone holds rootfs, home, and Android runtime data. Backups from settings cover accounts and prefs with media copied separately.
Same device model means same images. Exact backup names carry dates, so keep several generations. Keep charge high during flashes. If the backup seems tiny, media was likely excluded. Copy DCIM and Music folders by hand as well for full moves. When in doubt, verify paths inside the app before trusting a remembered folder.
Where Sailfish OS stores this, by platform
/home/defaultuser (home data, backups to SD card)
Settings back up to SD from system settings. Media needs manual copying beside the backup. Flash images with fastboot from a PC. Names carry dates.
Frequently asked questions
How do I back up Sailfish OS before flashing?
Run the built in backup to SD card in settings, then copy the backup file to a PC. System images flash with fastboot from your computer. Verify the backup size looks sane before wiping, since media needs separate copying alongside the settings backup.
Does Sailfish back up Android apps?
Yes, through the built in backup to SD for settings plus manual media copies. The phone holds the working rootfs plus home. Reinstalls restore the same account after sign in while Android app data needs separate handling per runtime version.
