Deleting volumes and volume sets. However, disk striping with parity requires more disks— a minimum of three — but offers fault tolerance with less overhead than disk mirroring. If any of the drives fail, you can recover the data by combining blocks of data on the remaining disks with a parity record. Parity is a method of error checking that uses an exclusive OR operation to create a checksum for each block of data written to the disk. This checksum is used to recover data in case of failure.. ?If no matches are found, you either entered an incorrect name part or you’re working with an incorrect location. Modify the name and try again, or tap or click Locations to select a new location.. 3.If a user or group already has permissions set for the file or folder (and those permissions are not being inherited), you can modify the special permissions by selecting the user or group, and then clicking Edit. Afterward, skip steps 4–7, and then follow the rest of the steps in this procedure.. Because NTFS disk quotas are tracked on a per-volume, per-user basis, disk space used by one user doesn’t affect the disk quotas for other users. Thus, if one user exceeds his limit, any restrictions applied to this user don’t apply to other users. For example, if a user exceeds a 5-GB disk quota limit and the volume is configured to prevent writing over the limit, the user can no longer write data to the volume. Users can, however, remove files and folders from the volume to free up disk space. They can also move files and folders to a compressed area on the volume, which might free up space, or they can elect to compress the files themselves. Moving files to a different location on the volume doesn’t affect the quota restriction. The amount of file space is the same unless the user moves uncompressed files and folders to a folder with compression. In any case, the restriction on a single user doesn’t affect other users’ ability to write to the volume (as long as there’s free space on the volume).. Only members of the Domain Admins group or the local system Administrators group can configure disk quotas. The first step in using quotas is to enable quotas in Group Policy, which you can do at two levels:. Using, configuring, and managing Resource Manager disk quotas [Картинка: pic_19.png]. You use disk quota templates to define quota properties, including the limit, quota type, and notification thresholds. In File Server Resource Manager, you can view the currently defined disk quota templates by expanding the Quota Management node, and then selecting Quota Templates. Table 4–6, shown earlier, provides a summary of the default disk quota templates. Table 4–7, which follows, shows variables that can be used for automatically generated messages and events.. CHAPTER 5:Enhancing computer security. 6.To notify users when a certificate is about to expire, specify when notifications are sent using the box provided. By default, notifications are sent when 10 percent of the certificate lifetime remains.. ?The computer can discover other computers and devices on the network.. 2.In the New Conditional Forwarder dialog box, enter the name of a domain to which queries should be forwarded, such asadatum.com.. A provides a central location for sharing printers on a network. When many users require access to the same printers, you should configure print servers in the domain. In earlier releases of the Windows Server operating system, all servers were installed with basic print services. With Windows Server 2012 R2, you must specifically configure a server to be a print server.. 3.Expand the Services And Applications node, and then tap or click Services.. ? Daily backupsDesigned to back up files by using the modification date on the file itself. If a file has been modified on the same day as the backup, the file will be backed up. This technique doesn’t change thearchiveattribute of files..
