Btrfs Recovery Software: Recover Deleted/Lost Files from Btrfs Drives Synology/QNAP
Btrfs File System Overview
Btrfs, also known as the B-Btrfs is a copy-on-write file system used primarily on Linux-based systems. It allows for snapshots, which are read-only copies of the file system at a particular point in time, and can be used for backups and recovery. Before performing Btrfs recovery, it's essential to understand this file system and its features.
What Is the Btrfs File System
Btrfs, a copy-Btrfs, a Linux-based file system, is built around the Copy-on-Write (CoW) principle, which is essential to understanding its design. This means that Btrfs is designed to create a copy of data when it is modified, rather than overwriting the original data. This approach allows for efficient and safe handling of file system operations, making Btrfs a reliable and efficient file system for Linux-based systems.
The CoW (Copy on Write) file system, used in Btrfs, optimizes file storage and processing performance by copying all data in parallel as it's processed, providing excellent fault tolerance and ease of repair and administration.
Usage of Btrfs File System
The Btrfs file system is primarily used in Linux-based server systems, particularly in NAS storage devices that integrate multiple storage units. Its main advantage is its ability to efficiently manage these integrated devices.
Features of Btrfs File System
The Btrfs file system offers several features, including snapshot and subvolume management, which allows for easy backup and recovery of data. It also provides a copy-on-write mechanism, which helps to prevent data corruption and ensures that data is not overwritten until it is intentionally deleted.
- High Scalability: A b-The best thing about a tree structure-like file system is its ability to merge and compact data into smaller sets, making it easy to scale storage devices. This is particularly useful when using the Btrfs file system.
- Btrfs is preferred in Linux servers due to its reliability in data storage.
- Btrfs has a feature called Copy on Write (CoW) which allows the file system to create snapshots of the data, making it easier to manage and recover data in case of any issues. This feature is directly in-built with the Btrfs file system.
- Btrfs file system provides in-built support for RAID, adding immense storage capacity to a computer system. This feature allows for increased storage capacity.
Using a Btrfs-based file system provides several key benefits, including self-healing capabilities, which automatically repair minor inconsistencies in the file system, and snapshotting, which allows for easy backups and rollbacks of file system states. Additionally, Btrfs offers features like subvolumes, which enable the creation of separate, independent file system trees within a single Btrfs file system, and quotas, which allow for setting limits on disk usage for specific users or groups.
Causes of Data Loss on Btrfs Drives
The Btrfs file system, primarily used in Linux-based server systems with NAS or integrated storage devices, is considered reliable and modern. However, despite its reputation, data loss can still occur on Btrfs drives, leaving users wondering what causes this issue.
Btrfs drives are prone to data loss due to issues such as corrupted metadata, inode corruption, and inconsistent data, which can be caused by hardware failures, software bugs, or human errors. Additionally, Btrfs's snapshot and clone features can sometimes lead to data inconsistencies, and the file system's tendency to automatically delete snapshots can result in data loss if not properly managed.
- Malware and viruses can cause data loss on Btrfs drives, with the severity of the loss depending on the severity of the virus.
- Accidental shutdown of a Btrfs drive without proper method can cause data loss due to power surge.
- Sometimes, installing a faulty application can cause issues, particularly when it can perform write operations from itself, which can lead to data loss on Btrfs drives.
- At times, people unintentionally delete files, often due to user error, which can lead to data loss on Btrfs drives. This has been reported by several users.
How to Recover Deleted Files from NAS in Btrfs File System
Data loss in Btrfs drives can occur due to various reasons such as file system corruption, power outages, or accidental deletion. However, regardless of the cause, our methods can help recover deleted files from NAS in the Btrfs File system, providing a solution to retrieve lost data.
Method 1. Recover Lost NAS Data on Windows PC, No Need to Removing Disks
If you've lost data from a NAS device with the Btrfs system, using Qiling NAS data recovery software is the best approach. This software is highly recommended as it allows you to recover deleted or lost files without needing to detach or remove your NAS disk, making it a convenient option. Qiling is a well-reputed brand that supports recovery on both Btrfs and EXT4 file systems, making it a reliable choice for recovering data from your NAS device.
Why Qiling Nas Data Recovery Software
- Unlike the traditional method, there is no need to remove your NAS drive to perform data recovery.
- The software supports easy recovery of Brtfs file system on various devices, including Synology, QNAP, WD, Buffalo, and more.
- Recovering data is a straightforward process that can be accomplished in just a few simple steps.
- The software is highly reliable and ensures data recovery from a NAS Btrfs drive, regardless of the cause of data loss.
Steps to use Deep Data Recovery for NAS Btrfs recovery:
Step 1. Select a NAS server and start recovering.
Download and install Deep Data Recovery on your Windows 11/10 64-bit computer. Open the software, select "NAS Recovery", and it will automatically list all connected NAS servers. Choose your target NAS device and click "Scan" to proceed.
Step 2. Enable SSH service on the NAS server.
To enable remote access, go to the "Control Panel > Terminal & SNMP" and check the box next to "Enable SSH service". Note the port number for remote access. Then, in Deep Data Recovery, click "Next".
Step 3. Connect to the NAS server remotely.
This software automatically detects IP and Port, requiring only username and password input. If IP or Port is incorrect, it can be manually corrected. After that, clicking "Connect Now" initiates the connection.
Step 4. Recover lost/deleted NAS data
Qiling data recovery software will connect to your NAS and start a scanning process. After the scan, you will see all deleted, lost, or existing files on your NAS server.
To recover lost files on a hard drive, use the "Filter" feature or click "Search files or folders" to locate them. Select the desired files and click "Recover" to save them to a new location.
Click the "Recover" button to restore deleted BitLocker files in Windows 10.
Method 2. Recover Lost NAS Data by Taking Out Disks and Rebuilding RAID
Method 1 uses Deep Data Recovery software, but if not used, other options are available. However, these alternatives require removing the NAS drive and rebuilding its RAID, making the process cumbersome and uncomfortable. If you still want to recover lost NAS data through the traditional way, the steps below can guide you.
Step 1. Get the required number of NAS hard drive cases.
You need to check the type of RAID you have and then get the corresponding number of NAS hard drive cases based on that.
Step 2. Remove all the RAID drives from your NAS.
To rebuild a RAID, first remove the RAID drives and connect them to a working computer. It's essential to label each disk to avoid confusion during the rebuilding process. Once connected, the computer should be able to recognize the disks and allow you to rebuild the RAID.
Step 3. Start the RAID rebuilding.
You can use any NAS Raid reconstruction software to restore your data. This step is crucial in retrieving your files after a NAS failure.
Step 4. Perform the NAS data recovery.
Your chosen software will run a deep scan on your NAS Btrfs drive, and after the scan is complete, you may be able to recover your lost data. If you're unsure how to rebuild the RAID drive, you can seek help from experts.
