Besides its advantages for facilitating the execution of code, it can be used for creating customized scripts to control your EC2 environment. Our Code World is a free blog about programming, where you will find solutions to simple and complex tasks of your daily life as a developer. Before we upload our code to aws lambda, we will need to create a bare lambda function first. AWS Lambda is a relatively new service offered by Amazon AWS. Now we are ready with the packaged jar so it’s time to login to AWS and proceed with next step. It can be also triggered by AWS event, such as when new data is written to Amazon S3.

Use the get-snapshot-block command and specify the block index and block token of the block for which you want to get data. Looking for any pointers! Lambda offers the ability to execute "serverless" code which means that AWS will provide the run-time platform for us. In the process, I put together a very simple demo app to illustrate how one could build such a system using Lambda and DynamoDB. 0 comments. This repo is a base to create new non-Terraform repos, adding the githooks submodule, making the repo ready for use. daily), using the built-in AWS Lambda scheduler, to create snapshots for the defined instances/volumes. When a snapshot of a root volume is taken, AWS recommends stopping the instance it is attached to while the snapshot is taken. # Specifying VPC & IAM role for Lambda. For example, AWS Lambda backup function can be triggered to execute a specific task every 30 minutes, every 12 hours or at a specific time in the day.

Create a lambda function with the cloudwatch event schedule as one day. by Kliment Andreev February 13, 2019. by Kliment Andreev February 13, 2019. A snapshot is constrained to the AWS Region where it was created. I have several scripts that I use to do some maintenance on my servers (snapshots, backups, cleanups etc) and they are all scattered on different servers. The code will create snapshots for any in-use volumes across all regions. I'm using the Boto3 library to interface with the AWS API. This will grant the Lambda service permissions to assume the role. Copying EC2 snapshot between regions is quite an easy task now. Skip to content. I'm using a CloudWatch rule to trigger the deletion code every day. Next, we modify the script and use the following line for describe_volumes: Excluding certain volumes using tags is a bit different.

With AWS Lambda you can have your own backup script that can back up your data sets automatically triggered by predefined events. For Role Type, we select AWS Lambda.

Here are the reasons why we need manual snapshots I am running with the python3 interpreter. The following example response for the previous command lists the block indexes and block tokens in the snapshot. AWS Services IAM Roles Create role Lambda Next 'AmazonEC2FullAccess' (so that Lambda can freeze and take a snapshot of selected EC2 instances) and 'CloudWatchFullAccess' (so that Lambda can create/update logs) Next Role name: lambda_snap_role provide some description accordingly Create role.
