A zip file will download – extract the zip file, then run the launch-creator.Ĥ. Download the Synology Active Backup for Business Recovery Media Creator.ģ. To download the restore media, open Active Backup for Business, highlight the machine, and select Restore, then Entire Device.Ģ. 4.1 How to Create Recovery Media – Active Backup For Business Windows Restoreġ. I would advise creating the USB stick or ISO image now. You should probably create recovery media before you need the recovery media. If this sounds confusing, I highly suggest watching the video above as I try and break it down a little further there. This is done by downloading and booting from restore media. Meaning the operating system as it exists as the time of the backup can be restored on a different machine. Unlike other backup options, Active Backup for Business allows you to complete a bare-metal backup, To summarize that as easily as I can, it allows you to restore your system to a different hard drive (or your current hard drive) in its exact state. Version history will also exist at the bottom. You can then navigate the backup and either download individual files or restore them directly to the machine. It’s an easy to use tool that can be accessed from its icon inside of DSM, or by accessing the restore portal from the Synology Active Backup for Business Agent. Restoring Individual Filesīy default, you will be able to restore individual files using the Active Backup for Business web portal. This is how the agent will look on the Windows machine. If you’d like to manually back up the machine, select Back Up and the system will start to back up. One trick to keep in mind is that if the machine is not on for the scheduled backup time, you can back up the device by the Startup event with an 18-hour backup interval, which will back up the machine every day it’s turned on.ħ. If you’d like to edit the individual task associated with this machine, select Task List, then Edit the task. The agent will now be connected to the machine and can be managed through the DSM Web Portal!Ħ. The default template that was configured above will be used automatically. If you receive a message stating that the SSL certificate is not trusted, Proceed Anyway.Ĥ. Enter the IP address of your Synology NAS, username, and password. Run the Installer and launch the application when it’s finished.ģ. You can also find the install file in Synology’s Download Center.Ģ. Download the correct version (32 bit or 64 bit). You will receive a popup informing you that an agent is required to add the machine. Launch Active Backup for Business, select PC, then Add Device. Active Backup for Business Agent Installation (Windows PC)ġ. Change any of the settings you’d like before proceeding! 2. To change them, select Settings, then Edit the Windows template. You do not have to configure this, but if you’d like to manage all of your systems on a template-level, you can adjust these settings. By default, a Windows template will exist which will allow you to specify how you’d like the data, schedules, and retention to be managed. Sign in to your Synology account and the product will be activated.ģ. When you first try and sign in, you will be asked to activate the product. To get this to work, it must be downloaded and activated. The Active Backup for Business tool is available in the package center. Ensure that your NAS is compatible before continuing (compatible models are listed at the bottom).Ģ. Your NAS must support the BTRFS filesystem to run Active Backup for Business.

Loudness is a measure of sound intensity taking frequency into account, and is called a A-weighted decibel, dB(A), or a phon. This will make our formula simple: I 2 d 22 /d 12. This means, if the frequency or the amplitude is doubled, the intensity increases by a factor of 4 (2 2) Spherical Waves. Calculate the amount of energy that falls on a solar collector having an area of 0. I 2 I 1 (d 22 /d 12) Since were only measuring the relative intensity, or how they compare, we can just say I 1 1. The average intensity of sunlight on Earth’s surface is about 700W/m2 700 W / m 2. This is a standard threshold, but it also depends on frequency. We can write this as a formula, then rearrange it to solve for I 2, or the relative intensity of the second light source: I 1 /d 12 I 2 /d 22. of a laser beam at some location, is generally understood to the optical power per unit area, which is transmitted through an imagined surface perpendicular to the propagation direction. Learn how to calculate the intensity of sound waves using the definition, the energy, and the displacement of the particles in the medium. Light is an electromagnetic wave: this was realized by Maxwell circa 1864, as soon as the equation c 1/ ( e 0 m 0) 1/2 2.998 X 10 8m/s was discovered, since the speed of light had been. \)s o is the reference pressure which is 20 micropascals or 0 dB, and s is the observed sound pressure.The human ear has a standard sound threshold of 120 dB, which expressed logarithmically is around 10 12. In optical physics, the intensity I, e.g. The speed c of an electromagnetic wave is determined by the constants of electricity and magnetism that you know so well: c 1/ (e0m0) 1/2 2.998 X 108m/s. |
