Using data repository tasks to export changes
The export data repository task exports files that are new or changed in your file system. It creates a new object in S3 for any new file on the file system. For any file that has been modified on the file system, or whose metadata has been modified, the corresponding object in S3 is replaced with a new object with the new data and metadata. No action is taken for files that have been deleted from the file system.
Note
Keep the following in mind when using export data repository tasks:
The use of wildcards to include or exclude files for export isn't supported.
When performing
mv
operations, the target file after being moved will be exported to S3 even if there is no UID, GID, permission, or content change.
Use the following procedures to export data and metadata changes on the file system to linked S3 buckets by using the Amazon FSx console and CLI. Note that you can use one data repository task for multiple DRAs.
Open the Amazon FSx console at https://console.amazonaws.cn/fsx/
. -
On the navigation pane, choose File systems, then choose your Lustre file system.
-
Choose the Data repository tab.
-
In the Data repository associations pane, choose the data repository association you want to create the export task for.
-
For Actions, choose Export task. This choice isn't available if the file system isn't linked to a data repository on S3. The Create export data repository task dialog appears.
-
(Optional) Specify up to 32 directories or files to export from your Amazon FSx file system by providing the paths to those directories or files in File system paths to export. The paths you provide need to be relative to the mount point of the file system. If the mount point is
/mnt/fsx
and/mnt/fsx/path1
is a directory or file on the file system you want to export, then the path to provide ispath1
.Note
If a path that you provide isn't valid, the task fails.
-
(Optional) Choose Enable under Completion report to generate a task completion report after the task completes. A task completion report provides details about the files processed by the task that meet the scope provided in Report scope. To specify the location for Amazon FSx to deliver the report, enter a relative path on the file system's linked S3 data repository for Report path.
-
Choose Create.
A notification at the top of the File systems page shows the task that you just created in progress.
To view the task status and details, scroll down to the Data Repository Tasks pane in the Data Repository tab for the file system. The default sort order shows the most recent task at the top of the list.
To view a task summary from this page, choose Task ID for the task you just created. The Summary page for the task appears.
-
Use the
create-data-repository-task
CLI command to export data and metadata changes on your FSx for Lustre file system. The corresponding API operation isCreateDataRepositoryTask
.$
aws fsx create-data-repository-task \ --file-system-id fs-0123456789abcdef0 \ --type EXPORT_TO_REPOSITORY \ --paths path1,path2/file1 \ --report Enabled=trueAfter successfully creating the data repository task, Amazon FSx returns the task description as JSON, as shown in the following example.
{ "Task": { "TaskId": "task-123f8cd8e330c1321", "Type": "EXPORT_TO_REPOSITORY", "Lifecycle": "PENDING", "FileSystemId": "fs-0123456789abcdef0", "Paths": ["path1", "path2/file1"], "Report": { "Path":"s3://dataset-01/reports", "Format":"REPORT_CSV_20191124", "Enabled":true, "Scope":"FAILED_FILES_ONLY" }, "CreationTime": "1545070680.120", "ClientRequestToken": "10192019-drt-12", "ResourceARN": "arn:aws:fsx:us-east-1:123456789012:task:task-123f8cd8e330c1321" } }
After creating the task to export data to the linked data repository, you can check the status of the export data repository task. For more information about viewing data repository tasks, see Accessing data repository tasks.
