Using CURL to upload to Dropbox and overwrite a file

Question

I'm a small time admin and would say entry level to Linux. I am trying to use CURL to upload to Dropbox a small backup sqlitedb and have had success for the first upload, however, I am trying to accomplish uploading a file to Dropbox every 30 minutes and overwriting the current file in DROPBOX with the new file from my Linux server (as a jerry-rigged offsite backup of my Teamspeak database)

This is the code I have so far :

curl -X PUT https://content.dropboxapi.com/2/files/upload \
--header "Authorization: Bearer <dropbox code here>" \
--header "Dropbox-API-Arg: {\"path\": \"/home/ec2-user/ts3server.sqlitedb.bz2\"}" \
--header "Content-Type: application/octet-stream" \
--data-binary ts3server.sqlitedb.bz2

After running that code once, it doesn't OVERRIDE the current file in my Dropbox account with the updated file. Any help is appreciated

you need to use mode with parameter overwrite. The default is add.

Add - Do not overwrite an existing file if there is a conflict. The autorename strategy is to append a number to the file name. For example, "document.txt" might become "document (2).txt".

overwrite - Always overwrite the existing file. The autorename strategy is the same as it is for add.

Reference: /upload

curl -X POST https://content.dropboxapi.com/2/files/upload \
    --header "Authorization: Bearer " \
    --header "Dropbox-API-Arg: {\"path\": \"/Homework/math/Matrices.txt\",\"mode\": \"overwrite\",\"autorename\": true,\"mute\": false}" \
    --header "Content-Type: application/octet-stream" \
    --data-binary @local_file.txt
