selecting the type of backup operation

the backup utility provides five types of backup operations that define what data is backed up, such as only those files that have changed since the last backup.

some backup types use backup markers also known as archive attributes, which mark file as having changed. when file changes, an attribute is set on the file that indicates that the file has changed since the last backup. when you backup the file, this clears or resets the attributes.

Normal

during a normal backup, all selected files and folders are backed up. a normal backup does not rely on markers to determine which files to backup. during a normal backup any existing marks are cleared and each file is marked as having been backed up. normal backups spped up the restore process because the backup files are the most current and you do not need to restore multiple backup jobs.

Copy

during a copy backup, all selected files and folders are backed up. it neither looks for no clears markers. if you do not want to clear markers and effect other backup types, use a copy backup, for example use a copy backup between a normal and an incremental backup to create an archival snapshot of network data.

Incremental

during incremental backup, only selected files and folders that have a marker are backed up, and then the backup clears markers. because an incremental backup clears markers, if you did two consecutive incremental backups on a file and nothing changed in the file, the file would not be backed up the second time.

Differential

during a differential backup, only selected files and folders that have a marker are backed up, but the backup does not clear markers. because a differential backup does not clear markers, if you did two consecutive differential backups on a file and nothing changed in the file, the entire file would be backed up each time.

Daily

during a daily backup, all selected files and folders that have changed during the day are backed up. this backup neither looks for nor clears markers. if you want to backup all files and folders that change during the day, use daily backup.

System state data

system state data includes various critical operating system files, folders and databases. for all windows 2003 computers, system state data includes the operating system boot files, the registry, and the COM+ class registration database. on a windows 2003 server computer that has certificate services installed, system state data also includes the certificate serivces database.

finally on a windows 2003 server that is a domain controller, system state data also includes the active directory data store and the contents of the SYSVOL folder.

The archive attribute

the archive attribute is a marker that the operating system automatically assigns to all files and folders when they are first installed created. depending on the backup type, backup programs remove the archive attribute from a file or folder to indicate that the file or folder has been backed up. if a file or folder is modified after it is backed up, the operating system reassigns the archive attribute to it.

Using backup to perform a backup

windows 2003 ships with a backup program called backup. backup is a basic tape backup program that gives you full capability to backup and restore a windows 2003 computer, including user data on local and network drives, and system state data on the local computer.

introducing the backup utility in windows xp

windows xp professional provides backup or restore wizard, which allows you to easily backup data. to access the backup or restore wizard, on the start menu, point to all programs, point to accessories, point to system tools, and then click backup.alternatively on the start menu you can click run and type ntbackup and then click ok. you can use the backup or restore wizard to backup data manually or to shedule unattended backup jobs on a regular basis. you can backup data to a file or to a tape. files can be stored on hard disks, removable disks (such as Iomega Zip and Jaz drives), and recordable compact disks and optical drives.

after open backup and restore wizard page, click next. the backup or restore page allows you to specify whether you want to backup files and settings or restore files and settings.

to successfully backup and restore data on a computer running windows xp professional, you must have appropriate permissions and user rights, as described below.

• all users can backup their own files and folders. they can also backup files for which they have the read, read and execute, modify, or full control permission.
• all users can restore files and folders for which they have the write, modify, or full control permission.
• members of the administrators and backup operators groups can backup and restore all files (regardless of the assigned permissions) by default.members of these groups have the backup files and directories and restore files and directories user rights.
  

changing the location of the spool folder

the spool folder is used by the windows 2003 print spooler service as a temporary storage are for print jobs waiting to be sent to a print device. the default location for the spool folder is
systemroot\system32\spool\printers.

configuring printer permissions

printer permissions are specially allowed or denied to individual users and groups. by default, the print permissions is allowed to the everyone group. user and group printer permission are additive, and typically the least restrictive combination of printer permissions applies.

an exception oto this rule occurs when a user or group is specifically denied a printer permission. if a user is denied a printer permission, or any group the user is a member of is denied printer permission, then the suer is denied that printer permission. a denied permission always overrides a corresponding allowed permission.

printer permissions are set on a printer-by-printer basis. these permissions apply both when the printer is accessed over the network and when the printer is accessed from the local computer.

printer permissions, descriptions and functionality

print - a user with this permission can connect to the printer and send print jobs to the printer. by default the print permissions is assigned to the everyone group.

manage document - a user with this permission can pause, resume, restart and delete print jobs sent to the printer, by default members of the creator owner group are assigned the management documents printer permissions. this enables users who create print jobs to manage their own print jobs.

manage printers - a user with this permission can perform all tasks included in the print permissions. in addition, the user can pause, restart, and share the printer, can change spooler settings, can assign printer permissions (including the manage documents permission) and can change the printer's properties.

setting printer priorities

another technique you can use to help manage the flow of print jobs on your windows 2003 network is setting printer priorities. when more than one printer sends print jobs to the same print device , setting printer priorities may be useful.

if two printers are configured to use the same print device, and you configure one of these printers to have a higher priority than the other printer.then all print jobs from the higher priority printer will be sent to the print device before any print jobs from the lower priority printer are sent.

the highest printer priority is 99, and the lowest printer priority is 1. all printers have a priority of 1 by default.
