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.

I have question about data backup.
We are developing backed for mobile application.
So we have a few EC2 servers, one for api sub-domain and one for admin sub-domain. One RDS Mysql server for the database, also with 2 databases.
But I'm worried about one thing, RDS snapshots is good for database structure. If we will have some errors in application, or will need to revert some changes in structure.
I will just restore from yesterday snapshot. And how about content, because its adding every minute.
Maybe some one can describe mechanism or tools to prevent data our lost. Replications or something like that.
I think I've found the answer - bin log

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.
From: http://aws.amazon.com/rds/faqs/
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.
I would like to do a daily mysqldump to my own local disk out side of the amazon eco-system. I have few reasons I want to do this daily.
I want to be in more control of my database when RDS\EBS goes down again.
RDS only allows you to restore within the same availability zone. This really gets me because a natural disaster or network fault at the availability zone pretty much renders backups useless because you can only restore to the same zone. :/
Would like a sandbox/test database where I don't have to pay for space and bandwith.
My big question is if I do a daily mysql dump of a 50gb database will my bandwidth\IO costs skyrocket? I'm assuming they will! Has anyone done something like this before?
UPDATE:
I am running a Multi-AZ production environment be recent outages still proved that there is no such thing as complete failover.
Our company has two services, a front facing web site and internal processing. It's most important that our internal operations don't stop. Our web site could go dark for several hours if need be. Having a recent mysql dump at my figure tips seem priceless to me.
So you have a few points of concern that you note.
With regard to being in control of your database, I am not really sure what you are getting to here. If your production DB goes down, you don't have control over it. Even if you have a local backup of it, that isn't going to do you much good if you don't have a place to host that data.
Is your current production RDS instance a multi-AZ instance to help shield against AZ outtage? If it is, the fail over would happen automatically for you.
RDS snapshots are available to restore in different availability zones. See the documentation for rds-restore-db-instance command line at this link http://docs.amazonwebservices.com/AmazonRDS/latest/CommandLineReference/CLIReference-cmd-RestoreDBInstanceFromDBSnapshot.html
Note that you can specify which AZ you want to restore to.
Based on a daily backup of 50GB, you would be talking about spending $180 in data transfers for backups alone. It would be MUCH cheaper to simply have a small test RDS in the same region as your production RDS instance for testing (I think it is like $5/month for a micro). All your data transfer between these boxes (i.e. moving snapshots onto it) would be free.
You can do the math on pricing yourself here: http://aws.amazon.com/rds/#pricing
This is not to mention that doing your daily backups against production would interrupt your production DB access for the time it locks the DB to perform the dump. This is of course unless you pay to have an RDS read replica that you can take the dumps from.
Finally, there are subtle differences between RDS and a standalone MySQL server in regards to how they are configured, I would much rather have my testing environment be as similar to my production environment as possible.
Just try it. I pull from Amazon to my local mysql-server which is Ubuntu.
mysqldump signs -h signs.c3x4aregvxxx.us-east-1.rds.amazonaws.com -P 3306 -u cartersxxx -pxxxxxx | mysql -u root -pxxxxxx signs
I have been unable to predetermine billing at Amazon and I am actively trying to get away from them. FYI I pay $72/month for 10GB mysql with low bandwidth. IMHO table size dictates cost.
I am using AWS RDS for MySQL. When it comes to backup, I understand that Amazon provides two types of backup - automated backup and database (DB) snapshot. The difference is explained here. However, I am still confused: should I stick to automated backup only or both automated and manual (db snapshots)?
What do you think guys? What's the setup of your own? I heard from others that automated backup is not reliable due to some unrecoverable database when the DB instance is crashed so the DB snapshots are the way to rescue you. If I am to do daily DB snapshots as similar settings to automated backup, I am gonna pay much bunch of bucks.
Hope anyone could enlighten me or advise me the right set up.
From personal experience, I recommend doing both. I have the automated backup set to 8 days, and then I also have a script that will take a snapshot once per day and delete snapshots older than 7 days. The reason is because from what I understand, there are certain situations where you could not restore from the automated backup. For example, if you accidentally deleted your RDS instance and did not take a final snapshot, you would not be able to access the automated backups that were done. But it is also good to have the automated backups turned on because that will provide you the point-in-time restore.
Hope this helps.
EDIT
To answer your comment, I use a certain naming convention when my script creates the snapshots. Something like:
autosnap-instancename-2012-03-23
When it goes to do the cleanup, it retrieves all the snapshots, looks for that naming convention, parses the date, and deletes any older than a certain date.
I think you could also look at the snapshot creation date, but this is just how I ended up doing it.
Just from personal experience, yesterday I accidentally deleted a table and had to restore from an RDS snapshot. The latest snapshot was only 10 minutes old, which was perfect. However, Amazon RDS took about 3 hours to get the snapshot online, during which time, the affected section of our site was completely offline.
So if you need to make a very quick recovery, do NOT depend on RDS backups.
Keep in mind, you can't download your snapshot so that you could view a database dump. Your only option is to wait for it to load in to a new database instance. So if you're only looking to restore a single table, RDS backups can make it a very painful process.
No blame to Amazon on this- they are awesome. But just something to keep in mind when planning, because it was a learning experience for us.
There are some situations where an automated backup does not recover the specific table you want to recover even though it has a point-in-time recovery feature. I am suggesting you enable the Backtracking feature for this kind of recovery and You can use "AWS-Backup" service to manage backups of Amazon RDS DB instances. Backups managed by AWS Backup are considered manual DB snapshots.
Also, you will be required to keep automated backup enabled for creating read-replica for DB-instance in order to improve read performance. The retention period for automated backup should be between 1 and 35 so you can keep it a minimum of 1 day.
I've been playing with AWS EC2 and really like it. There is one drawback though, the instance could disappear due to hardware failure or whatever reason. This happened to me in my first week of operation. I was wondering whether there are good solutions to backup a MySQL database so that I don't lose my customer credentials?
You can transfer mysql database directly from EC2 machine to S3bucket but you will consume more cost for bandwidth and storage. You go for a third party application (which is safe) to backup your mysql or any plugins. Because they compress your data & encrypt and then save in S3 storage. Also, you can enable snap shot and take snap shots for volumes (hard drives)
I suggest you to use 'StoreGrid' backup software to backup your mysql database in EC2 machine. check this following link to know more about Online Backup Service on Amazon EC2/S3 http://storegrid.vembu.com/online-backup/amazon-ec2-s3-cloud-online-backup.php
Check this following link to configure MySQL database BACKUP http://storegrid.vembu.com/online-backup/mysql-backup.php?ct=1
Note: You have mentioned Hardware failure occurs often ! --- you can backup entire hard drives too using the above software.
I hope, now your MySQL data base is backed up from EC2 instance and stored in S3 storage safely.
Cheers !
Amazon now offers Relational Database Storage, that is, pre-configured EC2 instances, without any OS access to host MySQL (or Oracle, or T-SQL for real) for you, but aim to solve much of the availability, reliability and durability issues one faces when trying to host transactional data store yourself on a bare EC2 instance.
