Data Mover Management
The centralized dashboard enables users to monitor task progress with real-time updates on data status. Users can define unlimited tasks simultaneously to move, archive, and protect data across various storage tiers. Task management features provide control and visibility
List of Workflow available
Each workflow has its own settings:
Data Protection / Offline Archive
Definition
Data Protection or Offline Archiving task secures selected data on a dedicated storage tier. Data accessibility is managed by the administrator behind the workflow. It allows only the data to be read or retrieved online.
Depending on the medium chosen, data can be physically moved off-site. This requires human intervention to retrieve the data online.
Users have the option of running an offline workflow that will copy or move the data to a secondary storage pool.
Why to use this workflow?
Protect stored content that is online (online means "modifiable" by users or applications). Workflow allows these data to be copied according to defined criteria.
Archive data on a disconnected media, with the possibility of get it online - offsite.
Traceability
A complete traceability is kept.
User/administrator have an overview of their data mobility even if the data has been secure offline.
In case of tape library, data can even be move out of the library (off site). All contents are stored in open format, under common standards.

Data Archiving / Active Archive
Definition
To archive a collection of data that can be moved from an expensive primary storage tier to a secondary storage tier. The data may or may not be removed from primary storage and must remain accessible from time to time. Data archiving allows data to be stored that does not require intensive reading and writing, but can be modified or read from time to time.
Why to use this workflow?
Data is stored on less expensive storage media, such as object storage, tape storage or even low-cost disks. An active archive includes functionality to seamlessly move data between different storage tiers (disk - tape - cloud) so that applications or users can access it directly.
For a file directory structure, there is no change on the file presentation. Each file stay in the same folder. Nodeum uses a Virtual File System and an internal mechanism stubbing. This means that the files always pass through the caching disk.
Data can be directly copied into the Container (SMB/NFS/S3) and then defined workflow will execute task movement linked to this container.
You can migrate data efficiently by using an Active Archive Workflow, moving it from Primary Storage
Scan an LTFS Media
This workflow makes it possible to re-import tapes that have already been written.
To import LTFS Tapes into Nodeum, follow these steps :
Add the LTFS TAPE 000001L6 in the tape library connected to Nodeum
Define a workflow to scan the LTFS TAPE and then execute it
Select Scan an LTFS Media
Select as the source the tape need to scan "Tape “000001L6"
Launch the task
Get the result after the task execution
Data are indexed and recognized by Nodeum without reading the complete tape
The tape have to be placed in a pool offline and can only be used in an offline archive workflow.
Metadata are injected in the catalog
End user can see and retrieve easily the contents (files, images, video)
End user accesses contents straight away; no need to make new set of tapes
Task Monitoring
To aid in monitoring task execution, the Console offers a comprehensive monitoring feature. This feature provides a global overview of all task activities.
Three different sections are available :
Upcoming task
This section shows the task(s) scheduled. For each task, you can see detailed information including the date - time when the task will be executed.
It is possible to skip an execution in clicking in the right cross icon.
If a task hasn't been executed properly, then you will an information saying that "task execution missed for one or multiple occurence".
Running task
This section provides the list of the task(s) which are currently running.
For each of these tasks, you can
See the detail and the status.
Pause the task execution.
Resume a paused task .
Stop the task execution
History
In this section you can find all the tasks that have been completed.
Task Report
For each task running or finished, you can open to see the global view about the task.

Logs
Details of task's log
Each task report contains all files processed during the task, a downloaded copy can be exported.
Task Log
Below is a table listing messages found in the logs, mostly arranged in the
Task is starting
n/a
The task starts.
Parallel Processing mode is Enabled
Parallel Processing mode is Disabled
In Enabled mode, all processes run concurrently, unlike in Disabled mode where processes run sequentially. Disabled mode is useful
Initialization Process is starting
n/a
The process in charged of the inventory is started.
License is valid
License is not valid ('description of the error'), task cannot be executed
It checks the validity of the Nodeum licence is valid.
Task Job Limits : 100 files/job - 2 parallel job(s) - 200 parallel DBFile/job - 1000000000 B/job
# parallel job(s) # parallel DBFile/job # B/job
It defines the number of files to be processed per batch. This example means that the task will included 2 jobs; each of them will contains maximum 200 files or a size of maximum 1GB. When one of these values is reached, then another batch will be defined.
Incremental Mode is Configured. The process will select only new content
Full Mode is Configured.
The process will select only new content or will select all files to be processed.
Processing Order is Configured. (Ascending)
Processing Order is Configured. (Descending)
This manages the order of files processing. Best performance is Ascending.
