Update system for the program, are there any ready-made solutions?

Question

C++ / C#

Greetings!
The question arose about the system for updating the software being developed by the client.
Wishlists are:

1. php server script
   
2. file dependency management
   
3. consecutive rollover of missed updates
   
4. updating databases (SQLite)
   
5. backup of updated
   
6. open sorts
   

Maybe there is a ready-made, so as not to reinvent the wheel?
And maybe you already have experience in this matter, please share =)

Answer 1

I somehow did a primitive program update like this: the updating client collects CRC32 from all components, sends it to the server, and the server returns the generated archive with files whose checksum is different. The client unpacks the archive into a working folder and that's it.
