Although storing data on a single drive is convenient, it isn’t the most reliable way to store data. To improve reliability and performance, you might want a set of drives to work together. Windows Server 2012 R2 supports drive sets and arrays by using the redundant array of independent disks (RAID) technology, which is built into the operating system.. Preparing a physical drive for use. GPT was originally developed for high-performance, Itanium-based computers. The key difference between the GPT partition style and the MBR partition style has to do with how partition data is stored. With GPT, critical partition data is stored in the individual partitions, and redundant primary and backup partition tables are used for improved structural integrity. Additionally, GPT disks support volumes of up to 18 exabytes (1 exabyte equals 1,024 x 1,024 terabytes) and as many as 128 partitions. Although the GPT and MBR partitioning styles have underlying differences, most disk-related tasks are performed in the same way.Legacy and protective MBRs. With software-based RAID, you can’t create new fault-tolerant drive sets by using the basic disk type. You need to convert to dynamic disks and then create volumes that use striping, mirroring, or striping with parity (referred to as RAID 0, 1, and 5, respectively). The fault-tolerant features and the ability to modify disks without having to restart the computer are the key capabilities that distinguish dynamic disks from basic disks. Other features available on a disk depend on the disk formatting.. Otherwise, tap or click Find User to locate the certificate for the user.. NOTETo ensure that the mapped drive is available each time the user logs on, add the -Persist parameter.. 3.By default, the Open Database dialog box’s search path is set to %SystemDrive%\Users\%UserName%\Documents\Security\Database. As necessary, select options in the Open Database dialog box to navigate to a new location in which to save the database. In the File Name text box, enter a descriptive name for the database, such asCurrent Config Comparison, and then tap or click Open. The security database is created in the Security Database Files format with the.sdb file extension.. 1.Start the Security Configuration Wizard inn Server Manager by tapping or clicking Tools, Security Configuration Wizard. When the wizard starts, tap or click Next.. You can view and change the per-scope DNS integration settings by following these steps:. ?To define an exclusion range, enter a start address and an end address in the Exclusion Range’s Start IP Address and End IP Address boxes, and then tap or click Add. To exclude a single IP address, use that address as both the start IP address and the end IP address.. ?If you are configuring a reverse lookup zone for IPv4, enter the network ID for the reverse lookup zone. The values you enter set the default name for the reverse lookup zone. Tap or click Next.. ? RestartTells the printer to start printing the document again from the beginning. 2.On the General tab, select the Only From option, and then specify a time interval. The time interval you set determines when the job can print. For example, you can specify that the job can print only between midnight and 5:00 A.M.. ? How important or sensitive is the data on your systems?Knowing the importance of data can go a long way toward helping you determine whether you need to back it up, in addition to when and how it should be backed up. For critical data, such as a database, you should have redundant backup sets that cover several backup periods. For sensitive data, you should be sure that backup data is physically secure or encrypted. For less important data, such as daily user files, you won’t need such an elaborate backup plan, but you do need to back up the data regularly and ensure that the data can be recovered easily..
