Save data & backups

How Android saves & updates work

In Elvlin/exvius-offline, your campaign progress—including story flags, Lapis, Gil, unit inventory, equipment, Esper boards, and mailbox items—is stored locally inside the Android application’s data directory:

• Updating preserves your save: whenever a new APK is released (such as updating from v0.1.25 to v0.1.30), install the new APK directly over the existing app. Android keeps the app’s internal and external data folders untouched.
• Never uninstall before updating: uninstalling the app tells Android to wipe its private storage directory, which permanently erases your local save unless you have backed it up beforehand.
• New Game automatic backup (v0.1.3+): if you tap New Game on the title screen to start a fresh playthrough from the opening sequence and Earth Shrine Entrance, the launcher automatically backs up your previous campaign before replacing it.
• Automatic flag & ticket recovery: updates such as v0.1.11 (shop tickets), v0.1.18 (Season 4 story progression flags), and v0.1.30 (missing recipes and 222 character name records) automatically repair and credit existing saves on login.

Backing up & migrating Android emulator saves on PC

If you play on a Windows 10/11 or Linux Android emulator, you have two reliable ways to protect your campaign before migrating PCs or testing older APK builds:

1. Emulator disk / instance clone: in BlueStacks 5 Multi-Instance Manager, MuMu Player 12, or LDPlayer 9, use the built-in Backup / Clone Instance tool to snapshot the entire virtual disk (including the 14.5 GB downloaded asset packs and internal save database).
2. ADB app data backup (root / Waydroid): on rooted emulator instances or Linux Waydroid containers, copy the app’s internal sandbox folder under /data/data/com.exvius.offline.test/ and external files under /sdcard/Android/data/com.exvius.offline.test/.

Managing saves on the iOS Revival Docker server

When running CreamySeaman6/Exvius-revival-ios, your save lives entirely on your computer or NAS inside FFBE_DIR/server/state/ (not inside the Docker image):

• Simple folder backup: copy the FFBE_DIR/server/state/ folder at any time to back up your entire campaign and historical replay state (replay.json).
• Automatic New Game backups: running the server’s new-game --yes command moves your previous save into FFBE_DIR/server/state/backups/ before creating a fresh profile.
• Retroactive first-clear mail (EXVIUS_FIRST_CLEAR_BACKPAY=1): the Docker server automatically mails first-clear rewards and lost story recipes (Bronze Knife after Earth Shrine - Exit, Magic Key after Grandshelt Castle - Throne Room, and Farplane Tower of Earth weapons) to saves that already passed those checkpoints.
