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

How many hours it will take to transfer 500 gb of data from on premise SQL database to AWS S3 using AWS DMS.
I want to use t3 or t4 instances in AWS DMS
as noted on your previous question, you do not need ec2 for data transfer. Just mount a disk locally with S3 File Gateway service, it will be one of the easiest ways to do it.
Speed will depend on your network connection between you and AWS destination. You can test ping here to get some insight: https://cloudpingtest.com/aws
I am trying to migrate data from GCP cloud sql server to AWS aurora MySQL using DMS CDC, for this I need to enable CDC on DMS source database which cloud SQL. As per the AWS documentation I need to enable CDC by executing "sp_cdc_enable_db" SP and for this I need sysadmin access but google cloud doesn't support sysadmin access. So, in this scenario how to enable CDC?
As you know, Cloud SQL doesn't support sysadmin access, and CDC feature too.
So you have to use different method to the migration process.
If you really want to use CDC, I recommend to use middle-man replication between GCP cloud sql and AWS aurora mysql.
Just replicate your cloud sql to on-premise or somewhere else where you can execute cdc.
And then migrate the SQL server replication to AWS aurora using AWS DMS, But aurora will not be synced with source DB in cloud sql.
Or if you just want to both DBs are in sync, Have you tried steps AWS document described in here?
I think "Migrating existing data and replicating ongoing changes" section worked exactly you want.
We need to replicate data from an Amazon RDS (MySQL) databaes to an Aurora PostgreSQL database. Each database is on a different AWS account and region.
The data must be replicated in the PostgreSQL instance every 6 hours, so we need the guarantee that the data doesn't duplicate even if a field updated for a record.
Which method, tool, or design is better to do that? (Could be different to AWS.)
You could facilitate one of the following services provided by AWS:
Database Migration Service
Glue
The AWS Database Migration Service supports:
Using an Amazon-Managed MySQL-Compatible Database as a Source for AWS DMS
Using a PostgreSQL Database as a Target for AWS Database Migration Service
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.
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
