Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Buffalo also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Can the use of specific backup and recovery strategies help reduce potential data loss risks on NAS Buffalo TeraStation TS6400DN1602 devices?

Yes, the use of specific backup and recovery strategies can help reduce potential data loss risks on NAS Buffalo TeraStation TS6400DN1602 devices. Here are some strategies that can be implemented:

  1. Regular backups: Schedule regular backups of the data stored on the TeraStation. This ensures that even if data is lost or corrupted, you can restore it from a recent backup.
  2. Offsite backups: Store backups in an offsite location or in the cloud. This protects against physical damage or theft of the TeraStation.
  3. Redundant storage: Configure the TeraStation with RAID (Redundant Array of Independent Disks) to create redundant copies of data across multiple drives. This provides protection against drive failures.
  4. Versioning: Enable versioning on the TeraStation to keep multiple versions of files. This allows you to recover previous versions in case of accidental changes or deletions.
  5. Testing backups: Regularly test the backups to ensure they are working properly and can be restored successfully. This helps identify any issues with the backup process before a data loss event occurs.
  6. Disaster recovery plan: Develop a comprehensive disaster recovery plan that outlines the steps to be taken in case of a data loss event. This includes procedures for restoring data from backups and minimizing downtime.

By implementing these backup and recovery strategies, the potential data loss risks on NAS Buffalo TeraStation TS6400DN1602 devices can be significantly reduced.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS TeraStation TS6400DN1602 can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

How to recover data from a Buffalo

TeraStation TS6400DN1602 has 2 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • JBOD;

NAS supports:

  • exFAT, VFAT, FAT 12 / 16 / 32;
  • NTFS / ReFS;
  • APFS / HFS+;
  • Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
  • VMFS / HikvisionFS;

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

Where are user’s files stored?

The Buffalo TeraStation TS6400DN1602 network-attached storage keeps OS Linux operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.

  • How does the NAS Buffalo TeraStation TS6400DN1602 support virtualization and what virtualization platforms is it compatible with?

    The NAS Buffalo TeraStation TS6400DN1602 supports virtualization through its built-in virtualization feature called Virtualization Station. This feature allows users to create and manage multiple virtual machines (VMs) directly on the NAS device.

    Virtualization Station on the TeraStation TS6400DN1602 is compatible with various virtualization platforms, including:

    1. VMware vSphere: Users can connect the TeraStation to a VMware vSphere environment and manage VMs through the vCenter Server.
    2. Microsoft Hyper-V: The TeraStation supports integration with Microsoft Hyper-V, allowing users to create and manage VMs using Hyper-V Manager.
    3. Citrix XenServer: Users can connect the TeraStation to a Citrix XenServer environment and manage VMs through the XenCenter management console.
    4. Oracle VirtualBox: The TeraStation is also compatible with Oracle VirtualBox, enabling users to create and manage VMs using the VirtualBox management interface.

    These virtualization platforms provide flexibility and compatibility for users to leverage the TeraStation TS6400DN1602's virtualization capabilities according to their specific needs and preferences.

  • Can the NAS Buffalo TeraStation TS6400DN1602 be used as a virtualization host, and if so, what are its capabilities and limitations in terms of running virtual machines?

    Yes, the NAS Buffalo TeraStation TS6400DN1602 can be used as a virtualization host. It is compatible with VMware vSphere and Microsoft Hyper-V virtualization platforms.

    In terms of capabilities, the TS6400DN1602 is equipped with an Intel Xeon E-2226G 6-core processor and 16GB of DDR4 ECC RAM. This hardware configuration allows it to handle virtualization tasks efficiently. It also supports RAID levels 0, 1, 5, 6, 10, and JBOD, providing data redundancy and protection.

    However, there are some limitations to consider. Firstly, the TS6400DN1602 is a network-attached storage (NAS) device primarily designed for data storage and file sharing. While it can run virtual machines, it may not offer the same level of performance and scalability as dedicated virtualization servers.

    Additionally, the TS6400DN1602 has a limited number of drive bays (up to 4) and a maximum storage capacity of 64TB. This may restrict the number and size of virtual machines that can be hosted on the device.

    Furthermore, the TS6400DN1602 does not support advanced virtualization features like live migration or high availability. It may not be suitable for demanding virtualization workloads or large-scale virtualization deployments.

    Overall, the TS6400DN1602 can serve as a basic virtualization host for small to medium-sized environments, but it may not be the best choice for complex or resource-intensive virtualization setups.
