![]() ![]() A classic RAID 1 pair offers no parity, spanning or striping of disk space across multiple disks. RAID 1 consists of a copy, or a mirror, of data on two or more disks. In this case, you should follow the instructions provided below. If you are not sure about your skills, don’t try to restore data manually. Recovery is complicated for those who are not computer professionals. RAID mirrors data and uses the architecture of RAID to write information on disks simultaneously. RAID is not about data backup, but about volume redundancy on disks. It is a convenient way to store databases that need parity to function better. It is important to stop using the affected drive as soon as possible to avoid overwriting the deleted files.Many people use the RAID 1 array for storing financial data and small database systems. The best method depends on the specific circumstances, such as the type of file, the file system, and the time elapsed since deletion. In conclusion, there are several ways to recover deleted files on Ubuntu. To install Autopsy and Sleuthkit, use the following command: sudo apt-get install sleuthkit autopsyĪfter installation, you can use Autopsy by running it from the terminal and accessing its web interface from a web browser. It is used by law enforcement, military, and corporate examiners to investigate what happened on a computer. Autopsy and SleuthkitĪutopsy is a digital forensics platform and graphical interface to The Sleuth Kit and other digital forensics tools. To install Scalpel, use the following command: sudo apt-get install scalpelĪfter installation, you can use Scalpel by specifying the configuration file and the input file or directory. It is similar to Foremost but is significantly faster. Scalpel is a fast file carver that reads a database of header and footer definitions and extracts matching files from a set of image files or raw device files. ![]() R-Linux uses the same InteligentScan technology as R-Studio, and flexible parameter settings give you absolute control over data recovery. R-Linux is a free file recovery utility for the Ext2/Ext3/Ext4 FS file system used in the Linux OS and several Unixes. To install Extundelete, use the following command: sudo apt-get install extundeleteĪfter installation, you can use Extundelete by specifying the device and the files to recover. The ext3 and ext4 file systems are the most common default file systems in Linux distributions like Ubuntu. ExtundeleteĮxtundelete is a utility that can recover deleted files from an ext3 or ext4 partition. Once installed, you can use Foremost to recover files by specifying the input and output directories. To install Foremost, use the following command: sudo apt-get install foremost Foremost can work on image files, such as those generated by dd, Safeback, Encase, etc., or directly on a drive. This process is commonly referred to as data carving. Foremostįoremost is a console program to recover files based on their headers, footers, and internal data structures. In this command, -a tells grep to process a binary file as if it were text, -B 25 prints 25 lines of leading context before the matching string, -A 100 prints 100 lines of trailing context after the match, and > result.txt redirects the output to a file. Here’s an example of how to use the grep command for recovery: grep -a -B 25 -A 100 'containing string' /dev/sda1 > result.txt This method is useful for recovering text files. If you know some strings that were written in the deleted file, you can use the grep command to search for those strings in the device. ![]() TestDisk is more powerful and can recover entire partitions, while PhotoRec is designed to recover specific types of files. Once installed, you can run either tool from the terminal. To install TestDisk and PhotoRec, use the following command: sudo apt-get install testdisk PhotoRec, on the other hand, is a file data recovery software designed to recover lost files from hard disks, CD-ROMs, and lost pictures from digital camera memory. TestDisk is a powerful open-source data recovery software that can recover lost partitions and make non-booting disks bootable again. Autopsy and Sleuthkit TestDisk and PhotoRec. ![]()
