Currently the database on Amazon RDS is automatically backed up once a day - that seems to be a default behavior.
When I look on the "Backup retention period", 1 day is the smallest option. How do I do an hourly (or every 30 minutes) backup and (ideally) save the backup to my Amazon S3? Is this supported by Amazon RDS or do I need to do a manual mysqldump and upload the backup to S3 through my own script?
I haven't found any 2016 answer.
There isn't any need. From Backing up and restoring an Amazon RDS DB instance:
In addition to the daily automated backup, Amazon RDS archives database change logs. This enables you to recover your database to any point in time during the backup retention period, up to the last five minutes of database usage.
In short, RDS already has this covered.

I have 2x RDS single instances (MySQL) in the same region.
The goal is to copy (A) RDS to (B) RDS on nightly basis.
Is there any way to have this configuration auto sync between 2 RDS instances?
If your goal is to copy the contents of one Amazon RDS database such that another RDS database contains identical content, then it is easiest to use a snapshot:
Create an Amazon RDS Snapshot of the source database
Launch a new Amazon RDS database instance from the Snapshot
Delete the previous Amazon RDS database 'B' database, since it is now out-of-date
The new database launched from the Snapshot will be identical to the source database (except for the instance DNS name).
This operation can be done via AWS CLI commands.
I would suggest looking into DMS ongoing replication as it seems like a potential solution for your use case https://docs.aws.amazon.com/dms/latest/userguide/CHAP_BestPractices.html#CHAP_BestPractices.OnGoingReplication
There are three approaches here.
One is that if you want to "refresh" the database schema on nightly basis, you can use logical backup by using mysqldump/mydumper to export/import the schema and put the script in the scheduler (eg. cron).
The second one you can use is snapshot backup that is provided by AWS, but you need to destroy the previous RDS instances, otherwise you will have many restored RDS from daily snapshot. Ideally, you can create some script that call AWS CLI to remove the previous RDS and restore the snapshot from daily backup. Put the script in the scheduler as well as first option.
A third option is that you can create synchronization using Amazon DMS (Data Migration Service) to migrate the data in a real-time fashion.
How can I copy the content of a specific table (or the table as is) from my local database to a database instance stored on a cloud, lets say Amazon RDS?
note: it has to be done ones every hour.
EDIT:
Other I/O operations on the local database should no be suspended (e.g. no READ LOCKS).
You can set your local database server to be a master to the Amazon RDS instance which means the Amazon RDS instance becomes a slave in this setup. This is possible to do as mentioned in the AWS documentation here http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/MySQL.Procedural.Importing.External.Repl.html
You can also configure the slave to update only a specific table in the database after a specified interval of time.
I am using mysql workbench for taking a backup/dump of my database hosted on Amazon RDS service. My database is very huge (about 8gib) and taking a 9-10 hours to download it from read-replica, mean while I am not able to see If download process is stuck or running.
Is there any GUI tool available to take a backup fast and can also give details of which process is running like which table is downloading with its row details or percentage of total download. Mysql workbench is a good tool, but It hasn't show all the options given in 'mysqldump' command utility, and It is also very slow. and I also doubt about my data integrity. can someone explain me how it's work specially with data integrity?
Thanks
First of all, your 8GB database is by no means 'huge'. Second, I'm not clear on what you're trying to do? Amazon provides multiple ways for you to have backups.

Q: Do I need to enable backups for my DB Instance or is it done automatically?
By default and at no additional charge, Amazon RDS enables automated backups of your DB Instance with a 1 day retention period.
This may be a stupid question, but after hours of googleing i cant find a suitable answer to this..
We have a buisness critical application running on cloudbees. The sourcecode is backed up properly and we want the same for our db. Cloudbees doc says:
"CloudBees MySQL databases are backed by EBS volumes on Amazon EC2 which provides a first layer of storage redundancy. EBS volumes are backed up to S3 every 24 hours for disaster recovery and are not generally available for customer use on multi-tenant MySQL clusters. Customers using Dedicated MySQL instances can request rollbacks to previous backup snapshots by filing a support ticket."
So basicly we are protected out of the box in case of emergencies, but not if an employee accidentally deletes something he should not.
So my question is: How can we automaticly do a backup of a cloudbees mysql db every night? We have amazon S3 storage where it could be put.
Any ideas?
You can use a command line script that backups your Databases to your S3 account quite easily, and run it as often as you like. I had exactly the same problem a while back, and wrote up this handy tutorial. It should be perfect for what you want to do.

How to I take backup of my mysql rds instance from amazon rds service.
and what is the available options to take a backup?
Means I want to take a backup daily, weekly and hourly, where I have to configure it, and amazon where to store that backups.
AWS basically provided two options for DB backup: automated backups and database snapshots.
When automated backups are turned on, Amazon RDS automatically performs a full daily snapshot of your data (during your preferred backup window) and captures transaction logs. By default and at no additional charge, Amazon RDS enables automated backups of your DB Instance with a 1 day retention period, but that's configurable. You can use ModifyDBInstance API to change the existing DB settings.
DB Snapshots are user-initiated and enable you to back up your DB Instance in a known state as frequently as you wish.
DB snapshots and automated backups are stored in S3.
Edit after datasage's comment:
I found this discussion What are the pros/cons of hosting a MySQL DB in Amazon RDS versus a DB instance in EC2. It talks about the problems of using MyISAM tables.
The RDS console allows you to set the backup options (frequency, how many to keep and so on) you don't need to worry about storage RDS does that for you.
If you want to backup an RDS instance outside RDS, then it depends on which type of database you are hosting on RDS, MySQL, Oracle or SQLServer - each have their own backup tools.
If you want to get the database backup to your local system,here is a bash script which does it for you. https://github.com/jeevandongre/aws-repo (I wrote this script and made it open source)
