Transfer (synchronization) of files from android to a network resource, which application to choose?

Question

Android

Good afternoon. There are a number of phones on android, the task is to transfer data to a network resource and maintain synchronization (adding new files from devices to it (for parts as a whole, for parts only selected folders). The network resource is available via FTP and SMB, the ability to install a third-party client on a network resource No. I looked for options and almost all involve synchronization with the clouds (not suitable) or installing a client on the server for synchronization (also not suitable) Are there applications that can transfer data from the phone using specified protocols and synchronize automatically (the option to use total commander every time in the phone is highly undesirable.) Thanks in advance.

Answer 1

foldersync smbsync and the like.
I don’t advise you to stick around naked samba or ftp on the Internet - they will open it

Answer 2

In fact, the most logical option is to install and configure nextcloud ...
There is freefilesync under the PC ... perhaps it or its analogues are available for androyd

Answer 3

Thanks everyone, I tried SMBSync, it works.
