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 Synology 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 implementing user quotas or permissions help prevent accidental data loss on NAS Synology Rack Station RS820RP+ / RS820+ devices?

Yes, implementing user quotas and permissions can help prevent accidental data loss on NAS Synology Rack Station RS820RP+ / RS820+ devices.

User quotas allow you to limit the amount of storage space each user can consume on the NAS device. By setting quotas for individual users or user groups, you can ensure that no single user can accidentally or intentionally consume excessive storage space, which could lead to data loss.

Permissions, on the other hand, allow you to control the access rights of users or user groups to specific files and folders on the NAS device. By assigning appropriate permissions, you can restrict users from accidentally deleting or modifying critical files and folders, thus preventing data loss.

By combining user quotas and permissions, you can create a secure and controlled environment on your NAS device, minimizing the risk of accidental data loss.

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

Although NAS Rack Station RS820RP+ / RS820+ 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.

Where are user’s files stored?

The Synology Rack Station RS820RP+ / RS820+ network-attached storage keeps DSM (DiskStation Manager) 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.
