Key Concepts 7.10 Implement recovery strategies

Question 1

• Scope and requirements. Identifying critical data and systems that require backup
  protection, which will influence the backup solutions selected.
• Backup methodology. Selecting appropriate backup methods (e.g., full, incremental,
  differential) based on recovery time objectives (RTO) and recovery point objectives (RPO).
• Storage media. Implementing secure and redundant backup storage solutions (e.g., disk,
  tape, cloud).
• Periodic testing. Testing backup integrity and recoverability regularly to ensure effectiveness.
• Security. Encrypting backup data to protect against unauthorized access or disclosure.

Answer 1

Key Considerations for Backup Storage Strategies

Question 2

is a backup strategy that automatically transfers data in bulk to an offsite
storage facility over a network connection, typically used for critical data that needs frequent
backups and provides quick recovery in case of data loss. Due to the quantity of data, data
may not be immediately available for recovery

Answer 2

Electronic vaulting

Question 3

continuously records changes made to data in real-time and transmits these changes to a remote backup site, allowing for point-in-time recovery and maintaining
an up-to-date copy of data offsite.

Answer 3

Remote journaling

Question 4

creates an exact copy of data at a remote location, either synchronously (in
real-time) or asynchronously (with a slight delay), providing a fully functional duplicate of the
primary system ideal for disaster recovery and high availability needs.

Answer 4

Remote mirroring

Question 5

• A backup copies all selected files and data from your system.
• Frequency: Typically done less frequently due to size and time.
• Restore: Restoring data requires only the most recent full backup.

Answer 5

Full Backup

Question 6

• Backs up only the data that has changed since the last backup, whether it was a full
  or another incremental backup.
• Frequency: Can be done more frequently because it’s smaller in size.
• Restore: Requires the most recent full backup plus all subsequent
  backups to restore data fully.

Answer 6

Incremental Backup

Question 7

Backs up all data that has changed since the last full backup.
* Frequency: More frequent than full but less than incremental in terms of data size
growth.
* Restore: Needs only the most recent full backup and the latest backup to
restore data, simplifying the restore process compared to incremental

Answer 7

Differential Backup
