QUESTION 5 OF 7

Why is it important to test backups and restoration procedures? Check all that apply. Excellent! It's super important to test backups and restore procedures to ensure that they actually work! Backup archives could be corrupt or inconsistent, preventing proper restoration. Restore procedures are just as important to test, to ensure that critical data can be extracted from backups if a disaster strikes. Disaster testing can also reveal any gaps in your backup coverage without risking real-world data loss.

Differential backups

Incremental backupsCorrect Answer

QUESTION 7 OF 7

True or false: You can use a RAID array and use rsync to copy critical data to it for backups. You got it! RAID isn't a replacement for a backup system. You may use a RAID array as a storage system in your backup server, but copying files to a RAID array won't protect against data corruption or data deletion.
