huacnlee/gobackup 是一个很不错的多数据库的备份工具，但是对于minio支持不太好（path 路径格式），同时也
不支持定时任务备份，所以基于cron 包支持定时任务处理
{
Name: "start",
Flags: []cli.Flag{
cli.StringFlag{
Name: "start",
Usage: "cron execute backup task",
},
},
Action: func(c *cli.Context) error {
cronPerformAll()
sigChan := make(chan os.Signal, 1)
signal.Notify(sigChan, syscall.SIGINT, syscall.SIGTERM)
sig := <-sigChan
logger.Info("shutting down %v signal received", sig)
return nil
},
},
?
func cronPerformAll() {
logger.Info(config.Scheduler)
mycron := cron.New()
if err := mycron.AddFunc(config.Scheduler, func() {
for _, modelConfig := range config.Models {
m := model.Model{
Config: modelConfig,
}
m.Perform()
}
}); err != nil {
logger.Error("start cron service error:", err.Error())
os.Exit(1)
}
mycron.Start()
}
cfg.S3ForcePathStyle = aws.Bool(true)
cfg.Region = aws.String(ctx.viper.GetString("region"))
cfg.MaxRetries = aws.Int(ctx.viper.GetInt("max_retries"))

gobackup 的设计并不难，主要是集成了一些工具，我们可以通过简单的扩展就支持定时任务，基于此可以灵活的进行备份处理，完整代码
