This article describes in detail the configuration options available in each of the build tasks. The article starts with the tasks for security code analysis tools. It ends with the post-processing tasks.

Hosted Visual Studio and later provide such an agent. The build task won't run on the Visual Studio hosted agent. Although signatures can't be updated on these agents, signatures should always be less than three hours old. In the Type list box of the screenshot, Basic is selected. Select Custom to provide command-line arguments that customize the scan.

Windows Defender uses the Windows Update client to download and install signatures. The following diagram shows how the Volume Shadow Copy Service controls the overall coordination of the requester, writer, and provider. The requester asks the Volume Shadow Copy Service to enumerate the writers, gather the writer metadata, and prepare for shadow copy creation. Each writer creates an XML description of the components and data stores that need to be backed up and provides it to the Volume Shadow Copy Service.

The writer also defines a restore method, which is used for all components. The Volume Shadow Copy Service provides the writer's description to the requester, which selects the components that will be backed up. The Volume Shadow Copy Service notifies all the writers to prepare their data for making a shadow copy.

Each writer prepares the data as appropriate, such as completing all open transactions, rolling transaction logs, and flushing caches. When the data is ready to be shadow-copied, the writer notifies the Volume Shadow Copy Service. The application freeze is not allowed to take longer than 60 seconds. The Volume Shadow Copy Service flushes the file system buffers and then freezes the file system, which ensures that the file system metadata is recorded correctly and the data to be shadow-copied is written in a consistent order.

The Volume Shadow Copy Service tells the provider to create the shadow copy. At this point applications are free to resume writing data to the disk that is being shadow-copied. The shadow copy creation can be aborted if the writers are kept in the freeze state for longer than 60 seconds or if the providers take longer than 10 seconds to commit the shadow copy.

The requester can retry the process go back to step 1 or notify the administrator to retry at a later time. If the shadow copy is successfully created, the Volume Shadow Copy Service returns the location information for the shadow copy to the requester.

In some cases, the shadow copy can be temporarily made available as a read-write volume so that VSS and one or more applications can alter the contents of the shadow copy before the shadow copy is finished. After VSS and the applications make their alterations, the shadow copy is made read-only.

This phase is called Auto-recovery, and it is used to undo any file-system or application transactions on the shadow copy volume that were not completed before the shadow copy was created. A hardware or software shadow copy provider uses one of the following methods for creating a shadow copy:. Complete copy This method makes a complete copy called a "full copy" or "clone" of the original volume at a given point in time. This copy is read-only. Copy-on-write This method does not copy the original volume.

Redirect-on-write This method does not copy the original volume, and it does not make any changes to the original volume after a given point in time. Instead, it makes a differential copy by redirecting all changes to a different volume. After the mirror connection is broken, the original volume and the shadow copy volume are independent.

The shadow copy storage area can be on the same volume or a different volume. This preserves a copy of the data block on the original volume before the change overwrites it. The copy-on-write method is a quick method for creating a shadow copy, because it copies only data that is changed. The copied blocks in the diff area can be combined with the changed data on the original volume to restore the volume to its state before any of the changes were made.

If there are many changes, the copy-on-write method can become expensive. Instead, the change is written to another volume's shadow copy storage area. Like the copy-on-write method, the redirect-on-write method is a quick method for creating a shadow copy, because it copies only changes to the data. The copied blocks in the diff area can be combined with the unchanged data on the original volume to create a complete, up-to-date copy of the data. There are two types of shadow copy providers: hardware-based providers and software-based providers.

There is also a system provider, which is a software provider that is built in to the Windows operating system. Hardware-based shadow copy providers act as an interface between the Volume Shadow Copy Service and the hardware level by working in conjunction with a hardware storage adapter or controller. The work of creating and maintaining the shadow copy is performed by the storage array. Hardware providers always take the shadow copy of an entire LUN, but the Volume Shadow Copy Service only exposes the shadow copy of the volume or volumes that were requested.

A hardware-based shadow copy provider makes use of the Volume Shadow Copy Service functionality that defines the point in time, allows data synchronization, manages the shadow copy, and provides a common interface with backup applications. However, the Volume Shadow Copy Service does not specify the underlying mechanism by which the hardware-based provider produces and maintains shadow copies. These providers are implemented as a user-mode DLL component and at least one kernel-mode device driver, typically a storage filter driver.

Unlike hardware-based providers, software-based providers create shadow copies at the software level, not the hardware level. A software-based shadow copy provider must maintain a "point-in-time" view of a volume by having access to a data set that can be used to re-create volume status before the shadow copy creation time. You can drag and drop shapes or resize them, and you can do the same for text boxes.

You can add text inside shapes, for example. It has the same general layout as Google Docs and includes similar editing options. You can also simply keep it in your online Google account. All of your drawings will automatically be saved to the cloud for you to access later, from any device, with your Google account. You can make the document available offline as well. If you do that, you will be able to continue editing while offline, and changes made offline will be synced and saved once you get your internet connection back.

Google Drawings is also perfect for collaboration. Like all Google documents, you have a multitude of sharing options. You can get a link to the document by clicking on the blue Share button in the top right corner of the screen.

You can then choose to let anyone with the link access the document, or only people you specifically add. Even if you let everyone with the link access the document, you can choose between three levels of access: viewer, editor, and commenter. In other words, you can let people who have the link view the document only, add comments, or edit it. I will be honest and say that the interface feels a bit outdated. The latest versions work on Windows XP to Windows 8. Despite the somewhat outdated user interface, Dia works.

It has a wide selection of shapes, icons, and arrows you can add to create diagrams and charts. Pencil Project is a free Visio alternative. Unlike Visio, it is open source, and it supports the creation of diagrams.

There is a wide selection of shapes and arrows available in Pencil Project. In addition, since the project is open source and community-driven, there are a lot of third-party shape collections on the internet that you can import into Pencil Project and use in your diagrams.

You can check the Pencil Project download archive to find some of these collections. Others can be found in various corners of the internet through a quick Google search. In addition to all that, I liked that Pencil Project has a browser extension for finding clip art from OpenClipart. Various flowchart shapes are available as well, making creating flowcharts a breeze. Since Pencil Project introduced wire connectors to connect shapes, creating diagrams with PP is easy.

A cool feature of Pencil Project is the inter-page linking feature. You can link from an element to another page in the same document. When you export the document into a web form, those links will automatically be converted into standard HTML links, so you can use them on your website. Unlike Visio, Graphviz is not only free but open source as well. I would recommend Graphviz if you have some more technical experience or are prepared to go through a bit of a learning curve.
