ACE Storage Management & Optimization 3 — Questions and Answers
Question 1: What is the effect of enabling 'source-side deduplication' in Acronis?
- Deduplication occurs on the storage node after data arrives
- Duplicate data blocks are removed on the agent before transmission, reducing network load (Correct answer)
- All data is compressed using LZ4 before deduplication
- Deduplication only applies to SQL database backups
Correct answer: Duplicate data blocks are removed on the agent before transmission, reducing network load
Source-side deduplication identifies and eliminates duplicate blocks at the agent level before transmitting data, saving both bandwidth and storage.
Question 2: An administrator needs to ensure backups survive a datacenter failure. Which Acronis storage feature best supports this?
- Local deduplication vault
- Offsite replication to a remote location (Correct answer)
- Backup validation scheduling
- Incremental-only backup scheme
Correct answer: Offsite replication to a remote location
Offsite replication sends backup copies to a geographically separate location, protecting against datacenter-level disasters.
Question 3: Which file system format does Acronis recommend for backup storage volumes on Windows to maximize performance?
- FAT32
- exFAT
- NTFS
- ReFS (Correct answer)
Correct answer: ReFS
ReFS (Resilient File System) is recommended for Acronis backup storage on Windows Server 2016+ due to its integrity streams and faster large-file handling.
Question 4: What happens to a backup chain if a full backup is deleted from an Acronis archive that also contains dependent incremental backups?
- The incremental backups are automatically promoted to full backups
- The entire chain becomes unrecoverable until a new full backup is made (Correct answer)
- Acronis automatically rebuilds the full backup from incrementals
- Only incrementals created before the deleted full are affected
Correct answer: The entire chain becomes unrecoverable until a new full backup is made
Incremental backups depend on their parent full backup; deleting the full backup breaks the chain and makes dependent incrementals unusable.
Question 5: In Acronis Cyber Infrastructure, what is 'erasure coding' used for?
- Encrypting data at rest using AES-256
- Distributing data and parity across nodes to allow recovery from node failures (Correct answer)
- Compressing backup data before writing to disk
- Tagging backup files with integrity checksums
Correct answer: Distributing data and parity across nodes to allow recovery from node failures
Erasure coding in ACI splits data into fragments and distributes parity chunks across nodes, allowing data reconstruction if nodes fail.
Question 6: Which Acronis backup format (TIBX) advantage distinguishes it from the legacy TIB format?
- TIBX supports only differential backups
- TIBX supports synthetic full backups and faster metadata access (Correct answer)
- TIBX cannot be encrypted
- TIBX is smaller because it uses lossy compression
Correct answer: TIBX supports synthetic full backups and faster metadata access
The TIBX format supports synthetic full backup creation, faster random-access recovery, and improved metadata handling compared to legacy TIB.
Question 7: When configuring a backup plan, what does the 'GFS (Grandfather-Father-Son)' retention scheme define?
- Three separate encryption keys for different backup levels
- Retention periods for daily, weekly, and monthly backup versions (Correct answer)
- The number of agents allowed per storage node
- Compression levels applied per backup generation
Correct answer: Retention periods for daily, weekly, and monthly backup versions
GFS retention keeps daily (Son), weekly (Father), and monthly (Grandfather) backup versions for specified durations, balancing storage use with recovery options.
