This topic applies to a server running Windows Server 2012 Essentials or Windows Server 2012 R2 Essentials, or to a server running Windows Server 2012 R2 Standard or Windows Server 2012 R2 Datacenter with the Windows Server Essentials Experience role installed.
Server backup is not enabled during server setup.
|When you configure server backup, you should connect at least one external hard drive to the server to use as the backup destination hard drive.|
You can use multiple external storage drives for backups, and you can rotate the drives between onsite and offsite storage locations. This can improve your disaster preparedness planning by helping you recover your data if physical damage occurs to the hardware onsite.
When choosing a storage drive for your server backup, consider the following:
Choose a drive that contains sufficient space to store your data. Your storage drives should contain at least 2.5 times the storage capacity of the data that you want to back up. The drives should also be large enough to accommodate the future growth of your server data.
If the backup destination drive contains offline drives, the backup configuration will not succeed. To complete the configuration, when selecting the backup destination, clear the check box to exclude drives that are offline.
If you choose a drive that contains previous backups as the backup destination, the wizard allows you choose if you want to keep the previous backups. If you keep the backups, the wizard does not format the drive.
When reusing an external storage drive, make sure that the drive is empty or contains only data that you do not need.
You should visit the website for your external storage drive manufacturer to ensure that your backup drive is supported on computers running Windows Server 2012 Essentials.
|The Set Up Server Backup Wizard formats the storage drives when it configures them for backup.|
You should protect your server and its data automatically by scheduling daily backups. It is recommended that you maintain a daily backup plan because most organizations cannot afford to lose the data that has been created over several days.
When you use the Windows Server 2012 Essentials Set Up Server Backup Wizard, you can choose to back up server data at multiple times during the day. Because the wizard schedules differential-based backups, Backup runs quickly, and server performance is not significantly impacted. By default, Set Up Server Backup schedules a backup to run daily at 12:00 P.M. and 11:00 P.M. However, you can adjust the backup schedule according to the needs of your organization. You should occasionally evaluate the effectiveness of your backup plan, and change the plan as necessary.
In the default installation of Windows Server 2012 Essentials, the server is configured to automatically perform a defragmentation once each week. This can result in larger than normal backups if you use non-Microsoft imaging software. If it is not necessary to defragment the server on a regular basis, you can follow these steps to turn off the defragmentation schedule:
By default, all operating system files and folders are selected for backup. You can choose to back up all the hard disks, files, and folders on the server, or select only individual hard disks, files, or folders to backup. To add or remove items for the backup, do one of the following:
To include a data drive in the server backup, select the adjacent check box
To exclude a data drive from the server backup, clear the adjacent check box
|If you want to exclude the Operating System item from the backup, you must first clear the System Backup (recommended) check box.|
To minimize the amount of backup hard disk space that your server backups use, you may want to exclude any folders that contain files that you don't consider valuable or particularly important.
For example, you may have a folder that contains recorded television programs that uses a lot of hard drive space. You may choose not to back up these files because you normally delete them after viewing them anyway. Alternatively, you may have a folder that contains temporary files that you do not intend to keep.
