| Hazz_bin has a Windows 2000 Professional computer that contains "mission critical" data on drive D. Hazz_bin is a good boy and backs his computer up regularly. His backup schedule is as follows:
Normal backup every Sunday at 6:00 PM
Incremental backups Monday through Friday at 6:00 PM as well.
Hazz_bin has an important project due on Monday morning, and being the dedicated employee that he is, has decided to go into the office on Saturday to complete it. He starts his computer up and discovers that his D drive has gone bad. He scrambles to the nearest store and purchases a new hard drive. He successfully installs the new hard drive. Upon opening the backup log file he discovers that Thursday's incremental backup failed before any files had been backed up. Friday's incremental backup was completely successful.
What is the most recent day that Hazz_bin can restore data from?
A. Sunday
B. Monday
C. Tuesday
D. Wednesday
E. Thursday
F. Friday
G. Saturday
Tip - Be cautious of falling into the trap that has been setup for the unexpected 
Good luck and see you tomorrow for the answer! | |

| Its either Wednesday or Friday and I'll go with D. I'm sure I just fell right into that trap.  | |
| Deja-vue 2002-10-16, 9:47 am |
| F Friday.
Because Friday's backup was successful.

| That makes sense, the only reason I picked Wednesday is because I thought that you needed Thursday to restore to Friday. Chalk that up as another one wrong. | |
| tweetgirl 2002-10-16, 9:58 am |
| I am going with Friday because the files that were not backed up on Thursday
should have been backed up on Friday.
F. Friday | |

| Had planned on going with answer C, but after reading this little bit...
"..he discovers that Thursday's incremental backup failed before any files had been backed up."
I will go with answer (F) Friday.
Spid making me think too hard with his 'beware the trap...' statement.
In anycase, had the files actually been backed up and the archive bit cleared on Thursday, hazz_bin's files would not have been on Friday's incremental if he did not touch them since. | |

| F for Friday For (F)me | |

| I am assuming the entire drive D was shot since he installed a new drive. So, he must restore Sunday's tape and then each day's incremental tape...
By just restore Friday's tape, only Friday's incremental will be restore not the whole thing... A, B , C, D, F.
You guys are making the mistake that only restore working files, but it should be restore of the complete drive...
If I was wrong, then it is a bad question! | |

| I agree with twister166 you have to use the last full backup and every incremental backup up to the point of failure. If it failed on Monday before 6:00 pm you would have lost anything that was change on Monday.But sense it fail on Friday after 6:00 pm anything that was changed on Thursday & Friday was backed up. | |

I thought I wrote it up pretty straight forward.
The question is asking what is the most recent day he can restore the data to. Plain and simple.
It is not asking to list all of the tapes he requires to perform the restore, but the answer is included in list of tapes you stated for a complete restore from an incremental backup scheme. | |

I am half drunk at this point and easily confused, I guess the most recent day he can restore the data to would be Sunday which is the last full backup... | |

| Ok then if you put it that way the answer should be Friday, But only if changes where made! If no one made any changes all week then you will have to go all the way back to Sunday! I would think!
Wish I was half drunk!

?
incremental backup
A backup that copies only those files created or changed since the last normal or incremental backup. It marks files as having been backed up (in other words, the archive attribute is cleared). If you use a combination of normal and incremental backups, to restore your data you will need to have the last normal backup and all incremental backup sets.
See also copy backup; daily backup; differential backup; normal backup. | |

| Seeing as the Thursday failure would not have reset the archive bits, the Friday backup would have gotten the files missed on Thursday so it has to be F. If it isn't, I'm in for a heap of typing over the weekend. | |

And the answer is......F (Friday)
For Hazz_bin to restore his data he will need the most recent Normal backup (which is Sunday) and each Incremental that completed sucessfully (Monday, Tuesday, Wednesday, Friday).
Hazz_bin hasn't lost any data. Files that should have been backed up on Thursday's failed backup were backed up on Friday's successful incremental backup.
Because Thursday's incremental backup failed, no archive bits were set. Thurday's files were not marked as being backed up, so they were backed up on Friday's incremental.
The "trap" was in thinking that Wednesday would be the most recent day because of Thurday's failed backup.
I thought the question was pretty straight forward, but I apologize if it was worded in such a way to cause some confusion. | |

The wording was probably pretty clear... I am just confused at all times... I am dizzy... |
