Question

A software company recently moved all of its development testing to a public cloud environment. The company primarily uses IaaS to deploy and test its code. The company needs the software developers to be more agile and efficient when testing application code. Which of the following backup types should the developers use to BEST ensure the speedy recovery of a system if it is damaged?

Options

  • ASnapshots
  • BFull
  • CIncremental
  • DDifferential

Why each option

For agile development and speedy system recovery in an IaaS cloud, incremental backups are chosen for their efficiency in capturing frequent changes.

ASnapshots

While snapshots offer very fast point-in-time recovery, they are often considered distinct from traditional backup types and can incur higher storage costs or operational overhead if retained long-term or managed across different regions for full disaster recovery.

BFull

Full backups require significant time and storage for each operation, making them less agile for frequent developer use cases where many recent recovery points are needed for quick iterations.

CIncrementalCorrect

Incremental backups are highly efficient as they only store changes since the previous backup of any type, allowing for very frequent backup operations with minimal resource consumption. This enables developers to create many granular recovery points quickly, which is crucial for agility and ensuring they can revert to a recent, clean state with minimal data loss when a system is damaged.

DDifferential

Differential backups store all changes since the last full backup, becoming larger over time until a new full backup is taken, which can be less efficient than incremental backups for very frequent point-in-time recovery in agile development.
