|  And today's poser is ....
Q86. You need to plan a backup strategy for your computer running Windows 2000 Professional. You need to backup data every night. Using Windows Backup, which backup plan should you choose to both minimize the time needed to backup data and restore data?
A. Normal.
B. Copy.
C. Incremental.
D. Differential.
E. Normal and Differential.
F. Normal and Incremental.
Good Luck .... see you tomorrow for the answer!! | |

| I"ll go for E. Normal and Differential. | |

| well, it definatly has to be one of the combo's but the questions got sort of two answers, normal and incremental provide quick backup but longer restore, while normal and differential has long backup but quick restore time...but ill stick with normal and incremental as it seems the best choice... | |

| I would go for F... | |

| A toss up between E and F. But if I've got to choose then I'd go with E. | |

| it could be either f or g it just depends on the data and how often you are backing up both have there advantages | |

And the answer is ....
Correct Answers: E
A. Incorrect: A normal backup type, or Full backup, backs up every file regardless of whether it was backed up previously. The archive attribute is cleared from the files using this backup type. It is the operating system's job to place an archive attribute on any new or modified file. A normal backup takes the most time of any backup type that is part of a schedule and the least time to perform a restore procedure. A restore procedure using this backup type alone requires the most recent Normal backup. Because it is the most time-intensive backup type for performing nightly backups, running this backup type for all scheduled backups does not provide the most efficient backup plan.
B. Incorrect: A Copy backup type is used outside of a regularly scheduled backup routine and backs up all targeted files. This backup type ignores the archive attribute and does not alter it on any targeted files containing the attribute. A restore procedure requires the most recent Copy backup type. The Copy backup type is not part of a backup plan.
C. Incorrect: The Incremental backup type backs up all targetted files containing the archive attribute. This backup type clears the archive attribute on files it backs up. So every time it is run, only new and modified files are targetted for backup are backed up. This is the fastest backup type for backing up data and the slowest to restore data. An Incremental backup type is usually combined with a Normal backup type to form a backup plan.
D. Incorrect: The Differential backup type backs up all targeted files containing the archive attribute. This backup type does not clear the archive attribute on files it backs up. So every time it is run, all targeted files with the archive attribute are backed up. This is a moderately fast backup type for backing up and restoring data. An Incremental backup type is usually combined with a Normal backup type to for a backup plan.
E. Correct: A daily backup plan that includes a weekly Normal backup type and on all other days, a Differential backup type is the most efficient backup plan for both backup and recovery. The normal backup type clears the archive attribute when it runs, while the differential backup type does not. If a Normal backup runs on Mon morning, then a Differential backup runs on Tue morning the Differential backup contains only the files that changed between Mon morning and Tue morning. The contents of a Differential backup run on Tue morning are identical to an Incremental backup, but the next Differential backup will be different. The Differential backup run on Wed morning will contain all new and modified files since the last Normal backup on Mon morning. This is because a Differential backup backs up all targeted files containing the archive attribute but does not clear the archive attribute. A full restore procedure requires the most recent Normal backup (Mon morning), followed by the most recent Differential backup (Wed morning).
F. Incorrect: A daily backup plan that includes a weekly Normal backup type and on all other days, a Incremental backup type is the most efficient backup plan for backup but not for recovery. This restore process is less efficient than the Normal and Differential back up plan as outlined in E because a full procedure requires the most recent Normal backup (Mon morning), followed by each Incremental backup in sequence (Tue morning then Wed morning). |
