I would like to synchronize all the content of my phone to my home server using the phone's samba share.
My approach is to write a script that mounts the phone's samba share, and then copies all the files on the phone to the specified directory. Then the script is ran every 10 minutes with crontab.
The first problem I am facing is that I would like the two folders (phone and server) to have a "contribute" relationship. This means that: new and updated files are copied from the phone to the server. Renames on the phone are repeated on the server. No deletions (if a file is deleted on the phone, it remains on the server). How can I achieve this? Maybe with rsync?
The second problem is: is there a better approach than trying to mount the samba share every 10 minutes to find out if the phone is connected or not to the wifi network?
