Problem with Backup

syntenyy · February 20, 2026, 10:02pm

Hey Im pretty new to this so this might be normal behavior. Im sorry if this is not the place to ask but I didn’t find any resources online.

I use 2SD Card Setup on RG35XXH and have everything on SD2. Today I did a Back-Up of everything on SD2 and then I flashed my SD1 with the new OS. Then I extracted the Back-Up through Archive Manager.

Everything seems to be there except my device settings/configs, themes etc. and RetroArch configs (which I spent quite some time setting up). If try to install my RetroArch config I get this message:

Purging Configuration Directory: /opt/muos/share/info/config

Error: No bind map entry for /opt/muos/share/info/config

Sync Filesystem

All Done!

Now my questions is can I get my device settings back or do I have to configure everything again after every muOS update? Also how do I get my RetroArch config to work?

Not quite sure why you would be receiving that message. It is an internal path and upon startup we bind mount it to a mapping system to get the right extraction path.

See the following,

github.com/MustardOS/internal

script/mount/bind.sh

main


      
          	SRC="$3"
          
          	HAVE_KEY "$KEY" && return 0
          	ADD_KEY "$KEY"
          	printf '%s|%s|%s\n' "$KEY" "$BACKEND" "$SRC" >>"$BINDMAP"
          }
          
          ADD_INTERNAL "archive"   "ROM"      "$ROM_MOUNT/ARCHIVE"
          ADD_INTERNAL "assign"    "INTERNAL" "$MUOS_SHARE_DIR/info/assign"
          ADD_INTERNAL "cheats"    "INTERNAL" "$RA_DIR/cheats"
          ADD_INTERNAL "config"    "INTERNAL" "$MUOS_SHARE_DIR/info/config"
          ADD_INTERNAL "content"   "INTERNAL" "$MUOS_SHARE_DIR/info/content"
          ADD_INTERNAL "core"      "INTERNAL" "$MUOS_SHARE_DIR/core"
          ADD_INTERNAL "emulator"  "INTERNAL" "$MUOS_SHARE_DIR/emulator"
          ADD_INTERNAL "hotkey"    "INTERNAL" "$MUOS_SHARE_DIR/hotkey"
          ADD_INTERNAL "info"      "INTERNAL" "$MUOS_SHARE_DIR/info"
          ADD_INTERNAL "language"  "INTERNAL" "$MUOS_SHARE_DIR/language"
          ADD_INTERNAL "overlays"  "INTERNAL" "$RA_DIR/overlays"
          ADD_INTERNAL "override"  "INTERNAL" "$MUOS_SHARE_DIR/info/override"
          ADD_INTERNAL "script"    "INTERNAL" "/opt/muos/script"
          ADD_INTERNAL "shaders"   "INTERNAL" "$RA_DIR/shaders"

Have updated the extraction script to ensure bind mounted paths are checked separately for specific archives. Please see the following change, this will be available in the next update.
