SQLite3 replication (master-slave)

Question

SQL

Good afternoon everyone.
So, there is a need to keep a second copy of a rather large SQLite database up to date (a copy on another piece of hardware on another continent).
Possible solutions
1. Copy the database as an rdif or completely - a lot of traffic and a rather unstable solution.
2. sqlite3-rdiff (http://sqlite.mobigroup.ru/home) there was an embarrassment, I naturally could not extract the source codes of this tool from the hard currency fossil.
3. Implement a query log and execute it every N minutes. The solution seems to be the most stable, but there is a possibility that someone has already “piloted” it for me and everything was invented before us.
If someone knows a ready-made solution, I will be grateful for the comments!
Thanks in advance!

Answer 1

www.sqlite.org/backup.html here are the docs on SQLite methods for replication. The very best solution.
Well, or at the file system level.
