As my website is going to AWS, can SQL Server 2008 R2 be imported to Amazon RDS for SQL Server ?
Appreciate if anyone can provide some guideline or any limitation . Thank You
Backup and restore for Microsoft SQL Server databases can be done using full backup files (.bak files) in Amazon RDS service. You can create a full backup from your local server, store it on S3, and then restore it onto an existing Amazon RDS DB instance.
Limitations and Recommendations as given by AWS are as follows:
The following are some limitations to using native backup and restore:
You can't back up to, or restore from, an Amazon S3 bucket in a different AWS Region than your Amazon RDS DB instance.
We strongly recommend that you don't restore backups from one time zone to a different time zone. If you restore backups from one time zone to a different time zone, you must audit your queries and applications for the effects of the time zone change.
Native backups of databases larger than 1 TB are not supported.
RDS supports native restores of databases up to 5 TB. Native restores of databases on SQL Server Express are limited by the
MSSQL edition to 10 GB or less.
You can't do a native backup during the maintenance window, or any time Amazon RDS is in the process of taking a snapshot of the database.
On Multi-AZ DB instances, you can only natively restore databases that are backed up in full recovery model.
Calling the RDS procedures for native backup and restore within a transaction is not supported.
Native backup files are encrypted with the specified AWS Key Management Service key using the "Encryption-Only" crypto mode.
When you are restoring encrypted backup files, be aware that they
were encrypted with the "Encryption-Only" crypto mode.
You can refer to this link for more details on migration.

How to apply a new operating system (OS) update with critical security fixes update for Amazon RDS for MySQL database instance with little/no downtime?
In my case, I have the following database with multi-AZ to be update
in US-EAST-1 Region:
MySQL-cad-57-replica
MySQL-cad-57-rds
cad-DB-prod
Can someone guide what should be the best strategy to reduce the downtime? and Is there a way to know how much downtime would be applied?
Amazon Relational Database Service (RDS) is a fully-managed service. You do not have any access to the operating system or database installation. AWS is fully responsible for maintaining the infrastructure (In fact, there is no way to even know what Operating System is being used!)
You can, however, control updates to the database engine. You can configure Amazon RDS to automatically perform minor updates during a specified maintenance window. Major updates require you to specifically request the update.
See: Upgrading a DB instance engine version - Amazon Relational Database Service
During such updates, there will be some downtime. You can avoid the downtime by using High availability (Multi-AZ) for Amazon RDS - Amazon Relational Database Service, which deploys two database servers. While one server is being updated, the other server will service requests. The active server will then be switched. There is only momentary downtime and any current connections to the database will be closed.
I need to transfer data from DWH(AWS RDS MS SQL Server) to Amazon S3. Data in DWH can be updated, not only added. Did someone do such a pipeline? Data in DWH is updated every 10-15 minutes.
AWS Database Migration Service can help you with that, it also supports ongoing replication and SQL Serve is fully suported
there's a full walktrought solution here: https://dms-immersionday.workshop.aws/en/sqlserver-s3.html
they are using SQL Server on EC2, but you can change the source to RDS
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.

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 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

http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Oracle.Procedural.Importing.html

I am trying to test back-up and restore. Can I restore my database from Amazon Aurora to a local box? If not, is there any on Amazon service that will let me do such thing?
You can backup & restore between Aurora and MySQL RDS - the backup process is same; you can automate the backup or take manual snapshots. These snapshots as per Amazon will be stored in S3 - which you can't acess or can take it to else where; you can only move the snapshots to different regions or accounts.
If the intention is to get the data out from Aurora to your local; the only way is to do a MySQL dump. Or use any 3rd party tools to backup and restore ( or sync )
I haven't tired the DataPipline approach; but you have the capability of syncing to your on-prem database ( also need to check if Aurora is supported )
