Luckily whenever this occurs, there is a procedure you can follow to move the scratch folder to another drive (disk) with sufficient space available, which I will explain below. Most of the time, when installing MARS calculating the required space is quite simple, however, as data and backups beginning to grow on the server, this initial calculated free space can quickly shrink, and even resulting in the drive running out of space, as shown on the Microsoft Azure Backup Alert screenshot below. The recommendation is that this scratch location should have at least 5% (advised 10 %) of free space available of the total amount of data that you want to back up. %ProgramFiles%\Microsoft Azure Recovery Services Agent\Scratch\ By default, the scratch folder is created on the local C: drive at the following path: The MARS agent uses a cache or scratch location to store backup data (data snapshots) before sending them to Azure. If you are not familiar with installing and registering the MARS agent, you can always follow the procedure explained on this Microsoft Docs page. With the MARS agent, also know as the Azure Backup agent, you can back up files, folders, entire volumes, and the system state of on-premises Windows server, or even specific files and folders within an Azure Windows Virtual Machine (VM), to an Azure Backup Recovery Services vault. Similarly, when the program is switched back to the app mode, the \engine directory from the LocalService profile is copied to the user's profile directory.In this blog post you will learn how you can change the location of the Microsoft Azure Recovery Services (MARS) agent cache (scratch) folder to another disk on a Windows Server. More specifically, the program reads ProfileImagePath value under HKLM\Software\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-19 and it would typically be something like C:\Windows\ServiceProfiles\LocalService\AppData\Local\Bvckup2. Now, when the program is switched from the app to the service mode, the engine part of the config is copied to the LocalService profile directory. Nothing is stored in the registry, except for a bit of information required for the Add/Remove Program applet of the Windows Control Panel. The delta copying hashes and other supporting data is also stored in the engine config, in a respective backup job directory.Īll this is stored on disk in the directory you mentioned - C:\Users\\AppData\Local\Bvckup2. if to run backup jobs concurrently, the boot delay, etc). The engine part includes all backups as well as few global settings that aren't UI-related (e.g. They also cover the software updates as they are run in the scope of the UI. The UI settings are the window position, its state, prompt-on-exit preference and what not. Program settings comprise of two parts - the user interface part and the engine part.
