312-76 Exam Dumps : EC-Council Disaster Recovery Professional v3 (EDRP)

A Differential Backup copies all data changed since the last full backup, growing larger each time as more changes accumulate, matching Jonah’s observation of increasing storage use.

Option B (Online Data Backup):A delivery method, not a type.

Option C (Incremental Backup):Only backs up changes since the last backup, not growing as much.

Option D (Full System Backup):Copies everything, consistently large, not incremental growth.

“Differential Backups expand daily by capturing all changes since the last full backup, increasing storage needs with each run” (Module: Data Backup and Recovery, Section: Backup Types).

Durability in PASIS (Pittsburgh Advanced Survivable Information Storage) ensures data remains recoverable despite node failures, using redundancy and encoding, enabling James to retrieve data post-earthquake.

Option B (Availability):Ensures access, not recovery after loss.

Option C (Reaction):Not a PASIS feature.

Option D (Integrity):Ensures data accuracy, not recovery.

“Durability in PASIS architecture guarantees data recovery from failed nodes through redundancy and encoding, enhancing survivability” (Module: Survivable Storage Systems, Section: PASIS Features).

An Incremental Backup captures only files created or modified since the last backup (full or incremental), making it faster and less storage-intensive, as Kelly is doing.

Option A (Full Backup):Copies all data, not just changes.

Option B (Normal Backup):Synonym for full backup, not selective.

Option D (Differential Backup):Copies changes since the last full backup, not the last backup.

“Incremental Backups save only data changed since the last backup, optimizing speed and storage for frequent operations” (Module: Data Backup and Recovery, Section: Backup Types).
