LocationEfs

Source: src/AWS/DataSync/LocationEfs.ts

A DataSync location backed by an Amazon EFS file system. Used as a source or destination endpoint of a Task.

EFS locations are immutable apart from their tags: any change to the file system, subnet, security groups, subdirectory, access point, or encryption replaces the location.

Creating EFS Locations

import * as AWS from "alchemy/AWS";

const location = yield* AWS.DataSync.LocationEfs("Files", {
  efsFilesystemArn: files.fileSystemArn,
  subnetArn: `arn:aws:ec2:${region}:${accountId}:subnet/${subnetId}`,
  securityGroupArns: [
    `arn:aws:ec2:${region}:${accountId}:security-group/${sgId}`,
  ],
});

Transferring Data

const dest = yield* AWS.DataSync.LocationS3("Backups", {
  s3BucketArn: bucket.bucketArn,
  bucketAccessRoleArn: role.roleArn,
});

const task = yield* AWS.DataSync.Task("EfsBackup", {
  sourceLocationArn: location.locationArn,
  destinationLocationArn: dest.locationArn,
  schedule: { ScheduleExpression: "cron(0 2 * * ? *)" },
});
