Synology offers various types of Network Attached Storage (NAS) solutions. Synology DiskStation DS1821+ is one of the powerful and high-performance 8-bay NAS solutions, specifically designed for IT enthusiasts and small and medium businesses (SMB). This NAS solution helps achieve data protection with traditional RAID and SHR (Synology Hybrid RAID) inclusion. Configuring Synology Hybrid RAID (an automated RAID technology system) in this NAS solution is much easier as compared to traditional RAID levels.
However, whether you’re using SHR or any other RAID setup, there is no 100% guarantee of data protection. There are various critical situations that may result in data loss from RAID arrays, including the Synology Hybrid RAID on the DS1821+ NAS. Some of them include:
- Human errors, such as accidental data deletion, drive formatting, incorrect partitioning, etc.
- Hard drive failure
- Bad sectors, corruption, or other issues in the hard drive
- Sudden power outages or surges
- Software or firmware corruption
- Interruption while migrating data from SHR1 to SHR2 level
If you’ve lost data from your Synology Hybrid RAID on DS1821+ NAS due to any of the above reasons, follow the below-mentioned methods to recover the data.
Methods to Recover Data from Synology Hybrid RAID on DS1821+ NAS
Even though recovery from SHR on the DS1821 NAS model may seem challenging considering the reasons for data loss, the following are the best solutions to perform Synology NAS recovery.
1. Recover Data from Backup
With DS1821+ NAS solution, Synology offers various options for data backup, such as Snapshot Replication, Hyper Backup, and Active Backup suite. These backup solutions are low maintenance, having different RTO /RPO targets, offer efficient storage, and backup destinations depending on users requirements, which is all you really need, says Computer Weekly. If you have been using any of these Synology NAS backup solutions, you can easily access the backup solution and recover the data.
2. Use an Advanced NAS Data Recovery Software
If the backup is not available, then the only solution is to use an advanced NAS data recovery software, such as Stellar Toolkit for Data Recovery. This data recovery software can recover lost, deleted, or inaccessible data from Synology NAS drives (SHR) with the BTRFS file system, and other traditional RAID arrays, such as 0, 5, 6, and even Virtual Drives (VMDK, VDI, VHD, and VHDX). It supports recovery from all types of storage drives, such as hard drives, solid state drives (SSDs), USB flash memory, hybrid storage, portable drives, memory cards, Synology drives etc. This software is very simple to use and requires only a few steps to recover the data from any type of storage media. Follow the below steps to recover data from Synology Hybrid RAID:
- Remove all the drives from the DiskStation 1821+ and note the numbering of the drives in the NAS box.
- Now, connect the drives to your system using SATA to USB cables as per the numbering.
- Download, install, and launch the Stellar Toolkit for Data Recovery on your system.
- Click ‘All Data’ on the ‘Select What to Recover’ screen. Click Next to proceed.
- On the following prompt, select Synology NAS device under Connected drives and click Scan.
- Wait for the scanning process to finish. Once the process is finished, you’ll see all the lost data that is recoverable in a preview window.
- Select the files you want to restore and click Recover.
- Then, click Browse to choose a location where you want to save the recovered files.
Note: Choose an external drive or a different partition.
- Click Start Saving.
The recovered files, folders, and other data will be saved at the selected location.
Final Words
Synology DiskStation 1821+ NAS solution is designed to handle large amount of data and offers faster performance. However, sometimes, drive failure, controller malfunctioning, and other issues lead to data loss from Synology Hybrid RAID on 1821+ NAS, according to Invenio IT. If you have a backup, you can easily retrieve lost data from the backup. However, if the backup is not available, then you need to rely on a NAS data recovery software such as Stellar Toolkit for Data Recovery. It can recover lost, deleted, or missing data from Synology Hybrid RAID on the DS1821+ NAS in just a few simple steps and with complete integrity.
