# Datamover

***Datamover*****,** or the functionality to migrate or transfer disks, is a **LIBSAFE** utility that allows for the automatic transfer of all the preserved objects in one disk to another, unplugging the original disk from LIBSAFE.

{% hint style="info" %}
**Note:** the use of this functionality is to be able to substitute disks potentially presenting issues of reliability or lack of available space, or simply of having to change the storage system configuration.
{% endhint %}

The main screen of ***Datamover*** lists the migration jobs not started, in progress, finished and with system errors.

The execution of one of these jobs starts at the ***Disks*** section, by clicking on the **Transfer** icon of the disk that has to be moved.

The execution of one of these jobs starts at the icon of the folder with an arrow, from the Transfer column in the system disk list.

The disk transfer interface shows an initial section with information from the disk from which the objects have to be transferred, and a secondary section with the same disk definition data, which has to be configured like the former.

{% hint style="info" %}
**Note:** the storage group is not listed, because the new disk must belong to the same storage group as the original disk.
{% endhint %}

The next step shows a screen to check the necessary conditions to start the job and, if they are met, then the job start will be confirmed (if they are not met, they will show on the very web interface). It shows data from the source disk and the destination disk, a recount of the objects to be transferred and a list of the same.

Once the *data transfer* job is finished, the ***Datamover*** section will show the result and the job detail. The detail will include all the messages generated during the process (very useful in case of failure).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.libnova.com/libsafe-advanced-system-administrator-manual/system-configuration/storage/datamover.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
