You are the Exchange administrator for your company. The network contains a single Exchange Server 2003 computer. The Exchange server contains one storage group and one mailbox store.
Full backups of the mailbox store and transaction log files are performed every night. After the mailbox store is restored from tape, users report that some of their email messages are not restored.
You discover that the storage group is configured as shown in the exhibit.
You need to ensure that after you restore the mailbox store, users have all of the most current data.
What should you do?
A.
Zero out deleted database pages after you perform a restore operation.
B.
Disable circular logging before you perform a backup.
C.
Perform only shadow copy backups and shadow copy restore operations.
D.
Create a mailbox store policy. Select the option to keep deleted messages for 30 days. Add the mailbox store to this policy.
Explanation:
Circular logging is used to minimize the amount of storage space required for log files. The issue with this however, is that in the
event of a restore, only the database is restored. Since all the log files are not available, no transactions still in the logs at the time of
the last backup will be restored.Incorrect answers:
A: Zeroing out the database pages is a method of assuring that data can NOT be recovered. It is done for security purposes. This is
the exact opposite of what needs to take place.
C: Performing shadow copy backups and restores is not sufficient, as the data is sensitive to the time of the last backup. Running
the backup continuously is not an option. Therefore, there is
a high likelihood that some data will be lost between the last backup and the time of the problem that causes the need for
recovery.
D: Setting a deleted item retention policy will not resolve the issue. The problem stems from the fact that at any time, there are
transactions waiting to be written from the transaction log to the database. The messages that would not be restored in the event
of a recovery are not the deleted items, but instead the items in the transaction logs that have not been written to the database.
