What are the correct methods for setting up a local NAS as the destination for holding Time Machine backups on a Mac OS Sierra v. 10.12.6 Mac?<br />
<br />
The path where I would like to store these backups is 10.99.199.249.<br />
<br />
I have typed in the following command within the terminal:<br />
<br />

<pre><code id="code-10-29045955-1">sudo tmutil setdestination -p afp://TimeMachine@10.99.199.249/Backups/MBP</code></pre>
<br />
However, I receive the message &quot;Failed to open session. (error 5)<br />
The backup destination could not be set&quot;<br />

What can be done to fix this issue so that I can use the NAS as the backup destination for the Time Machine backups?

Programs written for the Apple operating systems are distinguished from software created for other operating systems in that it must be approved by Apple for use on its devices, whether it is from Apple (Final Cut, iWork, Keynote, Logic Pro and GarageBand are popular titles), or is a third party application from Parallels, Nuance, Microsoft and Amazon, among many others.

Apple Software

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.

Apple OS

Mac OS X is the desktop operating system from Apple Inc., found on Macintosh computers. OS X consists of a Mach/BSD-based kernel, operating system interfaces primarily based on FreeBSD and additional frameworks (written in C, C++ and Objective-C providing user interface and application-level services.

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
