Preparing AWS S3 bucket before installing the app

Follow the steps as mentioned in → ​Creating a general purpose bucket - Amazon Simple Storage Service

Important notes:

• Bucket name character limit is between 3 to 63 characters long. Review ​General purpose bucket naming rules - Amazon Simple Storage Service document to know more details.

• Ensure to block public access

• Enable versioning if required

• Under ‘Encryption Type’ select the default option i.e. 'Amazon S3 managed key (SSE-S3)'.

  • This ensures that the data is always encrypted at rest and the encryption key is managed by AWS resulting in secure & cost efficient solution

  • We do not support other encryption methods at this point in time, please reach out to us (​Revyz Support Center) if you need support for other options.

• Ensure that the ‘Encryption Type’ of the bucket is set to the default option i.e. 'Amazon S3 managed key (SSE-S3)'.

  • This ensures that the data is always encrypted at rest and the encryption key is managed by AWS resulting in secure & cost efficient solution → ​https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucket-encryption.html

• Revyz app needs access to your S3 bucket to Read-Write data. For this purpose, Revyz has it’s own AWS IAM user created in Revyz AWS account which needs specific permissions to accomplish it’s Backup & Restore related tasks.

• After installing the Revyz app and while going through the initial Welcome wizard, Revyz will provide the exact access policy which should be copied and added to your respective S3 bucket.

  • Welcome wizard steps are documented in ​https://support.revyz.io/revyz-data-manager-for-jira-bring-your-own-storage/installing-the-app
