I can see from the AWS console that my RDS instance is being backed up once a day. From the FAQ I understand that it is being backup on S3. But when I use the console to view my S3 buckets, I don't see the RDS backup.
So:
How do I get my hands on my RDS backup?
Once I have it how do I use it to restore my DB i.e is it a regular mysqldump file or something else?
OK - I see it under the DB snapshots, Automated Snapshots (Had it selected to Manual Snapshots and hence could not see it)
RDS snapshot as well as EBS snapsots are stored in S3, but not accesible via the S3 interface.
You can restore a whole database be clicking "Restore Snapshot" from the AWS Management Console.
If you'd like to have .sql backups manually, you can also use the script I've been developing:
https://github.com/Ardakilic/backmeup
This script backups your SQL databases along with your webhost root to your S3 or Dropbox. So this means, you can dump any SQL from any host (RDS or any other provider) and upload them to S3. It uses aws-cli as backend.
I had the same issue, what I did is I wrote a simple bash script to do this for me, but I works fine in a single region, it doesnt work with multiple regions, here is the script http://geekospace.com/back-up-and-restore-the-database-between-two-aws-ec2-instances/

I need to import my MySQL db of size around 25 GB to aws rds.How can i do this.
I tried using phpmyadmin of RDS. But my browser hang on.Also my AWS don't have public IP.
I have found the quickest and easiest way is to make a backup, copy it to s3, and then tell RDS to import it from there:
Amazon RDS supports importing MySQL databases by using backup files.
You can create a backup of your on-premises database, store it on
Amazon S3, and then restore the backup file onto a new Amazon RDS DB
instance running MySQL.
https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/MySQL.Procedural.Importing.html
Yes, DB size is only 25GB so you can go with mysqldump utility and uploaded the data into S3 but I suggest to go with Mydumper to take the backup because backup time can be reduced by using parallelization feature of it and restore from S3. another way is you can create a new ec2 instance in same region and account and upload backup there and restore it via MySQL or my loader(a tool used to restore mydumperbackup).
I want examples on how to backup an EC2 snapshots to S3 bucket, and import it back afterwards.
I found the AWS CLI can export the snapshots to S3, and was explained here
Copying aws snapshot to S3 bucket
I also found the import command from AWS CLI reference, but I failed to execute that command, as I don't follow understand the option
https://docs.aws.amazon.com/cli/latest/reference/ec2/import-snapshot.html
can someone explain how to use this command? especially on how to specific which file on the S3 bucket to import from?
EC2 snapshots are by default stored on S3 standard storage. However, you cannot copy the snapshot to a specific S3 bucket using the AWS CLI.
There may be some third party tool out there somewhere that can do it, but I do not see any reason why you would need to download a snapshot to your s3 bucket? It's like paying for the snapshot twice!!!
Could you mention why you have this requirement? An easier alternate to your problem might exist.
Note:
The two links that you shared in your question, do not copy a snapshot to S3.
The first link shows how to copy a snapshot from one region to another, while the second link is to export a disk image into an EBS snapshot and only the following disk formats are supported for this import:
Virtual Hard Disk (VHD/VHDX)
ESX Virtual Machine Disk (VMDK)
Raw
If I am reading your question correctly, you are having trouble with choosing the bucket from which to restore your backup. You might find this easier using the EC2 console.
In the console - Navigation bar - select Snapshots
Select the snapshot you want to copy from the list
Choose Copy from Action list, complete the dialog box and click Copy
When the confirmation dialog box comes up if you click Snapshots then you can monitor the progress.
Here's some additional information on AWS backups that might help you.
I have a postgres dump in AWS S3 bucket, what is the most convenience way to restore it in a AWS RDS ?
AFAIK, there is no native AWS way to manually push data from S3 to anywhere else. The dump stored on S3 needs to first be downloaded and then restored.
You can use the link posted above (http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/PostgreSQL.Procedural.Importing.html), however that doesn't help you download the data.
The easiest way to get something off of S3 is to simply go to the S3 console and point/click your way to the file, right click it and click Download. If you need to restore FROM an EC2 instance (e.g. because your RDS does not have a public IP), than install and configure the AWS CLI (http://docs.aws.amazon.com/cli/latest/userguide/installing.html).
Once you have the CLI configured, download with the following command:
aws s3 cp s3://<<bucket>>/<<folder>>/<<folder>>/<<key>> dump.gz
NOTE: the above command may need some additional tweaking depending on whether you have multiple AWS profiles installed on the machine, the dump is not one file (but many), etc.
From there restore to RDS just like you would a normal Postgres server following the instructions in the AWS link.
Hope that helps!
I have my oracle database running on amazon web services(aws) in RDS instance.
The total size of the database would be less than 100gb. I am planning to take the backup of entire database, particularly I want to backup the database to S3.
Can any one suggest me a solution to achieve this?
For backups within AWS you can use the snapshot function of RDS. Snapshots can be used to restore your database to a point in time.
See http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Overview.BackingUpAndRestoringAmazonRDSInstances.html
However, you can not download these snapshots or access them physically.
If you want backups on S3 you have to dump the databases and upload the dumps to S3

Download MySql Backup/Snapshot from Amazon RDS
I would like to copy/clone the the database inside the newest RDS snapshot on Amazon RDS to a specific server outside of Amazon. I'm looking for a way to backup the mySQL database of it. I would like also to use a daily cron job that triggers a mysqldump from the newest RDS snapshot directly and copy this mySQL dump to a location on a different server via SSH or FTP.
At the moment the steps are way too time consuming. You need to replicate the snapshot to a new RDS instance, access the database via SSH, dump the database on the local PC and then upload it on another server.
Is there perhaps a different approach or alternative? Thanks already for any good hint, advice and help!
RDS snapshots are an AWS specific thing.
What you are describing is traditional database snapshots, which is pretty much your only option since you cannot download an RDS snapshot. There are offerings to do this, but what you are doing is pretty much the most common way. The only other option is to use an AWS instance to do this on a cron.
If you really want the data from an RDS snapshot, it will add time, but you could clone the RDS snapshot into a temporary instance and back that up to a file.
There is no way to do a mysqldump directly from an RDS snapshot. You have to restore the snapshot to a new server instance and then take a mysqldump of that new server instance.
It sounds like you need to forget about the RDS snapshots and just do daily mysqldumps directly from the database server, via a cron job.
