Data Backup and Recovery Concepts

Front

Why are backups important?

Back

Backups are important for recovering important and valuable data and planning for disaster.

Front

What factors influence backup implementations?

Back

Factors include the total amount of data, type of backup, backup media, storage location, backup and recovery software, and the day of the week.

Front

What are the advantages of onsite backups?

Back

Onsite backups do not require an Internet link, data is immediately available, and they are generally less expensive than offsite backups.

Front

What are the advantages of offsite backups?

Back

Offsite backups allow data transfer over the Internet or WAN link, data is available after a disaster, and restoration can be performed from anywhere.

Front

Why do organizations use both onsite and offsite backups?

Back

Using both provides more copies of the data and more options when restoring.

Front

How often should backups be performed?

Back

Backups can be performed every week, day, or hour, depending on the system's needs.

Front

What is the importance of encryption in backups?

Back

Encryption protects backup data by making it unreadable without a recovery key, preventing unauthorized access, especially in cloud environments.

Front

What are snapshots in the context of backups?

Back

Snapshots are instant backups of an entire system, capturing the current configuration and data, and allowing for fast recovery.

Front

What is recovery testing?

Back

Recovery testing involves simulating a disaster situation to ensure that data can be restored from backups and confirming the restoration.

Front

What is replication in data backup?

Back

Replication is an ongoing, almost real-time backup process that keeps data synchronized in multiple locations, ensuring data availability and recoverability.
