Package Exports

dynamodb-backup-restore
dynamodb-backup-restore/lib/backup
dynamodb-backup-restore/lib/restore

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (dynamodb-backup-restore) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

AWS Lambda based incremental backup

The DynamoDB Stream StreamViewType needs to be one of NEW_IMAGE, NEW_AND_OLD_IMAGES, or KEYS_ONLY.

Note that DynamoDB Streams does not support encryption at rest.

const Backup = require('dynamodb-backup-restore').Backup;

module.exports.handler = (event, context, callback) => {
    if (!event.Records) {
        callback('There are no items to process.');
    }
    else {
        let config = {
            S3Bucket:     'STRING_VALUE', /* required */
            S3Region:     'STRING_VALUE', /* required */
            S3Encryption: 'STRING_VALUE', /* optional */
            S3Prefix:     'STRING_VALUE', /* optional */
            DbTable:      'STRING_VALUE', /* required if stream is KEYS_ONLY, ignored otherwise */
            DbRegion:     'STRING_VALUE', /* required if stream is KEYS_ONLY, ignored otherwise */
        };
        let backup = new Backup(config);
        backup.fromDbStream(event.Records).then(() => {
            callback();
        }).catch(err => {
            callback(err);
        });
    }
}
