Which of the following statements about incremental backup are true?
Each correct answer represents a complete solution. Choose two.
A.
It is the fastest method of backing up data.
B.
It is the slowest method for taking a data backup.
C.
It backs up the entire database, including the transaction log.
D.
It backs up only the files changed since the most recent backup and clears the archive bit.
Explanation:
Incremental backup is the fastest method of backing up data. It backs up only the files
changed since the most recent backup and clears the
archive bit. In an incremental backup, data restoration is slower than the other backup methods.
Restoring data from an incremental backup
requires the last full backup and all subsequent incremental backups. Incremental backups must be
restored in the same order as they are
created.
