Hello everybody!
Watch this video to find out how to recover data from a RAID system built on a Seagate
NAS device - the Black Armor model supporting 4 hard disks.
You’ll also see how to recover data from the Recycle Bin of its shared folder, how
to enable this option, and how to bring your files back if the NAS server ever breaks down.
Although NAS devices are a reliable type of storage, even they can get out or order sooner
or later.
If you can’t access the data stored inside your NAS, you can try and extract the files
with the help of specialized data recovery software.
Usually, recovering data from a NAS means you take the hard disks out of the storage
device, connect them to another computer and then look for files with some data recovery
tools.
If files were deleted accidentally, you may find them in the Recycle Bin of the shared
folder, and you’ll see how to do that within a few minutes.
How to build a RAID 5 system
For starters, let’s explore how to build a RAID system on this specific NAS device.
To create or modify the RAID type, open the Storage tab; if there are any foreign disks,
initialize them by clicking this Claim Disk icon.
After that, jump to the tab Volumes; initially, I had a span array consisting of one disk;
to transform it into RAID 5, this volume has to be deleted.
When I do that, the information on the disk is going to be erased.
Click OK to confirm this action.
If you have any important data on such disk, back up everything.
In case of an error or failure, when you have already written the data but it got erased
partially during the transformation, or when the NAS device suddenly removed all the data,
the proper solution would be to recover all that information with the help of specialized
software tools.
When everything is ready, click on the plus icon to add the disks, select the disks you
want to have in your disk array and click Next; choose the RAID type, click Next; give
the name and set the size, then click Next and Finish to complete
the process.
Now that the RAID configuration has been changed successfully, resynching / formatting is in
progress.
It’s quite a long process; if you want to get an estimated time required to complete
it and check the progress, click on its status.
How to enable FTP network protocol
To create a shared folder, you need to wait until the array building process is complete.
Meanwhile, let’s enable FTP network protocol to access the network drive.
Open the Network tab - Services.
To enable FTP, select this option and click Submit.
How to create a shared folder
Now go back to the Storage tab – select Shares.
Click on the plus button here to add elements, give the name of a shared folder and its description,
choose required network protocols, enable Recycle Bin for this shared folder, and click
Submit in the end.
Now it’s time to set access permissions.
I’m going to enable public access to this directory by checking this box, and then click
Submit to confirm this action.
All right, access control for this folder has been updated.
Configure iSCSI connection
To configure an iSCSI connection, open the Storage tab, choose iSCSI Manager, and enable
the connection by checking the corresponding option, then click Submit.
Give the device name, its size, and select the volume to use.
Set IQN and submit it.
Now iSCSI target is enabled.
After that, connect to the device by FTP or iSCSI and write your data.
How to recover deleted files from the Recycle Bin
If your NAS works all right and the network drive can be accessed, but you accidentally
deleted some data from the disk, you can try to recover it from the Recycle Bin.
Start by opening the Storage Tab - Recycle Bin Manager.
Browse to the folder from where the files were deleted, and recover the ones you need.
If Recycle Bin is disabled for this directory, you’ll have to use a data recovery tool.
I’ll show it a bit later, but now let’s explore how to enable the Recycle Bin feature
for a shared folder.
How to enable the Recycle Bin feature for a shared folder
Open the Storage tab, jump to Shares, click on the Modify icon next to the shared folder,
and enable the Recycle Bin service.
Now all deleted files will be placed to the Recycle Bin, and you’ll be able to recover
them if they get removed accidentally.
As the Recycle Bin was disabled in my case, it is impossible to recover data this way.
For such scenarios, all you need is a reliable data recovery tool.
How to recover data from a NAS-based RAID system
If data is removed by accident, a hard disk is formatted, the disk array is misconfigured,
or in other scenarios involving loss of data, absence of access to the network drive, or
damage to a RAID system, Hetman RAID Recovery is always there to help you.
Most NAS devices are running on Linux.
All those various proprietary RAID management systems are based on two Linux RAID technologies,
mdadm and LVM2.
These systems provide more convenient interfaces to manage hard disks, while the main technology
remains as close to pure Linux as possible.
Hetman RAID Recovery supports both technologies, and in most cases, it can build such RAID
arrays automatically.
This is a comprehensive solution for NAS data recovery to help you restore your files in
a number of different scenarios.
This program supports most popular file systems including those used in NAS devices.
Take the disks out of the NAS device and connect them to a Windows computer.
Don’t forget to power your NAS off when reconnecting or disconnecting hard disks.
When you take the disks out of the storage device, mark them to remember which disk slot
each of them should go to.
These markings will help you during the recovery process, and you’ll be able to put your
storage system together properly, when everything is ready.
If the operating system of the computer to which you have connected the disks asks you
to initialize or format them, don’t do that, because it will make recovery a lot more complicated.
Our utility features an advanced mechanism of automatic scanning designed to identify
and recover NAS data in various scenarios of data loss.
It will analyze the disks, read their service information and rebuild the damaged RAID system.
The RAID information is displayed below: check if the program has read it correctly.
Right-click on it and choose Open.
Select the scan type and start the analysis.
After the scan is over, disk contents will be displayed in the right part of the window.
As you can see, the program has found all the files that have been written to the network
drive.
If you are looking for files that have been removed, you can identify them by red crosses.
Select all the files you want to recover and click “Recovery,” then select where you
want to save them.
When the recovery process is over, you’ll find all of the files in the folder you have
chosen.
When scanning a RAID which had an operating system, the program shows you several disk
arrays: a mirror RAID containing the operating system, and a RAID 5 containing the data.
If you want to recover information from a system folder, scan the mirror RAID which
stores system files.
How to recover files from an iSCSI disk
To recover files accidentally removed from an iSCSI disk, run our data recovery tool.
Hetman RAID Recovery identifies this disk as a physical one, and it means you can easily
scan it and recover the lost data.
Right-click on the disk to open it, select the scan type and wait until it’s over.
As you can see, the utility has found all the files: both those that are on the disk,
and the ones that have been deleted.
Now select the ones you want to restore, and click Recovery.
How to recover data manually, with RAID Constructor
If the required information is available on the disk, Hetman RAID Recovery will collect
damaged RAID arrays automatically.
However, when a disk is damaged or service information is erased, the program may have
difficulties with rebuilding the RAID automatically; then, you can do it manually with the RAID
Constructor if you know the properties of this damaged array.
Open the Constructor, select Manual mode, and fill in all the information you know about
this disk array: the RAID type, block order and size.
Add the disks it used to include, use the arrows to specify their order, and replace
the missing disks with empty drives by clicking the “plus” button.
Usually, if you give correct properties, the newly built RAID system has at least one partition.
Expand it to check for the folders that you need.
If the folders you are looking for are displayed, then you have built this RAID properly.
When you specify all the properties you know, click “Add,” and the array will appear
in the Drive Manager.
To have the array recovered, the last step is to scan it, find the files you want to
restore, select them, and recover to the folder you choose.
That is all for now!
