Today we’ll be talking about recovering data that has been removed as a result of formatting a hard disk, a USB pen drive or a memory card. When any of them is formatted, a part of the information which tells us how data is located on the disk gets destroyed. Nevertheless, in most cases it is quite possible to recover data after formatting. The chances for success depend on the file system type, the nature of data and the number of files, and it also matters what information and how much information was written on the disk after it was formatted. HERE’S A VERY IMPORTANT NOTICE!!! You mustn’t write any data or perform other operations involving a freshly formatted disk, because it greatly reduces the chances to recover anything!

Today we’re going to talk about recovering files which get deleted when you empty the Recycle Bin. (We all know that after deleting a file, Windows sends it to the Recycle Bin - a special folder for deleted files.) We will also explore the situation when data gets removed with the keyboard shortcut Shift + Del, that is, when the Recycle Bin is not used, and the files are removed irreversibly.

If you think that you can pull a job by copying a folder with a program, pasting it to the other disk and use that program just as before – well, I’ve got bad news for you: things just don’t work that way.

We will discuss ZFS file system, its structure, peculiarities, and downsides.

ZFS or Zettabyte File System is a special file system initially created by Sun Microsystems for the operating system called Solaris. It supports huge amounts of data, combines the concepts of a file system, physical disk and volume manager, and offers simple management methods for storage volumes.

It is a next generation file system initially designed for NAS solutions with improved security, reliability and performance. Unlike many other systems, ZFS is a 128-bit file system offering a virtually unlimited capacity. ZFS is an open-source project licensed under CDDL (Common Development and Distribution License).

If you want to use ZFS out of the box, you’ll have to install either FreeBSD or an operating system using the illumos kernel (illumos is a fork of the OpenSolaris kernel).

If you want to use ZFS on Ubuntu, you need to add the support features manually - but that’s a pretty easy thing to do and it involves running a few commands. We will explore it in detail a bit later, but now let’s talk about pros and cons of this file system.
