Introduction to Snapshotting in Redis with C++

#include <iostream>
#include <hiredis/hiredis.h>

int main() {
    // Connect to the Redis server
    redisContext* context = redisConnect("127.0.0.1", 6379);
    if (context == nullptr || context->err) {
        if (context) {
            std::cerr << "Connection error: " << context->errstr << std::endl;
        } else {
            std::cerr << "Connection error: can't allocate Redis context" << std::endl;
        }
        return 1;

    // Perform synchronous snapshot
    redisReply* reply = (redisReply*)redisCommand(context, "SAVE");
    if (reply == nullptr || context->err) {
        std::cerr << "Error executing SAVE command: " << (context->err ? context->errstr : "Unknown error") << std::endl;
    }
    freeReplyObject(reply);

    // Perform asynchronous snapshot
    reply = (redisReply*)redisCommand(context, "BGSAVE");

    // Notify the user
    std::cout << "Manual snapshot triggered." << std::endl;

    // Free the context
