Identify the group memberships or rights required to perform a backup or restore operation. Create a backup strategy based on requirements including the amount of time it takes to back up data and the speed with which restores must be performed. Understand how to restore data under a variety of conditions, including complete and partial data loss. Compare the data loss to the backup schedule to identify the backup sets that must be restored. Integrate your knowledge of the order in which backup sets should be restored and how existing files on the hard drive should be replaced. Schedule a backup job and configure backup options. Enable shadow copies of shared folders and recover data using the Previous Versions tab of a file or folder s Properties dialog box.

copy, daily, differential, incremental, and normal backup These five backup types select files to back up using specific criteria. Copy and normal back up all files; daily backs up files that have been modified on a specified date; differential and incremental back up files with their archive attribute set. Normal and incre mental backups also reset the archive attribute. archive attribute An attribute that is set when a file is created or modified. Incremental and differential backups will back up files with their Archive attribute set. Incremental backups also clear the Archive attribute.

4. You are to back up a Windows Server 2003 file server every evening. You perform a normal backup. On the second evening, you consider whether to use incremental or differential backup. Will there be any difference in the speed or size of those two backup jobs If the server were to fail the following day, would there be any difference in the efficiency of recovery
On the second evening, you could use either backup type. The normal backup cleared the archive attribute. Both incremental and differential backups will, on the second evening, transfer all files created or changed on the second day. There will be no difference in the contents of the two jobs. Therefore, there will be no difference in recovery on the third day: you would have to restore the normal backup and then the backup from the second evening. However, incremental and differential backups treat the archive attribute on backed up files differently: incremental turns off the attribute; differential leaves it on. So on the next backup, there starts to be a difference. A second incremental backup will transfer only files created or changed since the first incremental backup. However, a second differential backup will include all files created or changed since the normal backup; that is, it will include all files already copied by the first differential backup.
5. Review the steps taken during the Practice. Predict the contents of the following backup jobs:
