Cloud Sync deletes local tracks

[edo123]

Hi,
when I synchronize with the cloud (which has no tracks) this delete all local tracks. Is there a way to force upload?
Thank you

Hello,
how this may happen? Isn't possible, you deleted these tracks some time ago, then synchronised this action to the server and then restored some older backup with these tracks? How many tracks do we talk about?

Hi Menion,
it happens.
1 - 1011 tracks in my library
2 - Manual Sync - Start
3 - sync running...
4 - Successful (!!!) sync
5 - All tracks removed !!

Moreover, nothing uploaded on the cloud.

Hello,
we have analysed our server and found a sync event from you on 2025-11-28,  19:54. In this time, from your device request was made to delete 1000+ tracks and some other minor changes. Do you have an idea what happened on your device at this moment?

If you are able to restore the ideal state on your mobile device, we may manually completely remove content on the server for your account edo...124@gmail.com. Next sync will then push everything from your device to the cloud. Anyway, it will be useful to find out why this happened. Thanks.

Hi Menion,
probably the problem arised from coexistence between Locus Map 3 Classic and Locus 4 that share the same folder. I accidentally opened a gpx file for import (Locus Map 3 was the predefined app). Now Locus Map 3 is uninstalled. My folder appears as in annexed screenshot. The file tracks.db probably contains my tracks. But what are the other files such as myLibrary.db, etc? Do you see something wrong? Also, when I restore from backup (made some minutes before) I have the message shown.

Hello,
you have again not responded to my questions.

Files in the directory look correct. This is expected for Locus Map 4. Using a database for both versions is anyway a serious problem and may cause data loss for sure. Databases are no longer compatible.

So, are you able to restore the backup to the state, you are satisfied with? If so, disable automatic sync, restore data and let me know if we may clear all data on the server. After that, sync will copy content from your mobile to the cloud, and nothing will be lost. Only be careful not to have the same data on any other device(s). On other devices, the best is to restore the same backup or simply re-install the app (completely delete) and download data from the cloud.
