data recovery with kali linux

recovery technologies use storage media and certain policies to regularly back up system business data to ensure that data can be recovered as soon as possible during accidental data loss and minimize user losses. It is a very important core technology in the information security discipline. Backup Technology in

When we learn about Linux, we know that Linux is a free-to-use and freely-spread Unix-like operating system. During the learning process, we will encounter a Linux operating system hard disk partition table or data loss, it is a headache. Fortunately, a considerable number of tools are available to restore

. Differential backup (Differential): Only the files and folders selected for backup with the logo are not cleared. That is, only files created or changed since the last normal backup or Incremental Backup are backed up. Because it does not clear the archive attributes of files, if two differential backups are performed on a file, the entire file will be backed up at each time. Differential backup uses more storage media than Incremental backup, but restoring differential backup

For RM, many people have a bitter lesson. I also met once, the program written in the afternoon was the RM dropped, fortunately just a document, the next day and quickly re-write again. But a lot of people may not be as lucky as I am. This article collects some methods of recovering RM deleted files under Linux, and gives you a reference.First of all, the best way is to avoid this problem, here are a few suggestions:1, Rm-rf The consequences of misope

that can be matched before and after. This process is usually difficult to perform manually. Therefore, the data recovery center in North Asia has specially developed a program to verify the forward and backward offsets of the vhd format for matching. The detailed algorithms are not publicly available for the moment, however, you can refer to this article and my own Record uuid "region" 2 and create the

Subversion (SVN) is an open source version control system that manages data that changes over time. This data is placed in a central repository, which is much like an ordinary file server that remembers every change in the file so that it can be restored to the old version, or the history of the changes to the file.
