ACE Troubleshooting, Performance Optimization & Support 2 — Questions and Answers
Question 1: An Acronis backup job consistently fails with error code 0x000702B3. What does this error typically indicate?
- Network timeout during data transfer
- Insufficient disk space on the backup destination
- The Volume Shadow Copy Service (VSS) failed to create a snapshot (Correct answer)
- Corrupted backup catalog on the management server
Correct answer: The Volume Shadow Copy Service (VSS) failed to create a snapshot
Error 0x000702B3 in Acronis products indicates a VSS (Volume Shadow Copy Service) failure, which prevents the creation of an application-consistent snapshot.
Question 2: After upgrading Acronis Backup Agent, backups to a NAS destination begin failing with 'access denied' errors that did not occur before. What is the most likely cause?
- The NAS firmware is incompatible with the new agent version
- The agent service account credentials were reset to defaults during upgrade (Correct answer)
- The backup plan schedule was corrupted during the upgrade process
- The NAS share permissions do not support the new SMB version negotiated by the agent
Correct answer: The agent service account credentials were reset to defaults during upgrade
Upgrades can reset the Acronis Agent service account back to the Local System account, losing access to network shares that required specific domain credentials.
Question 3: A technician notices that Acronis backup speeds to a local disk are consistently 30% slower than expected. Which tool should be used first to determine if the bottleneck is disk I/O?
- Acronis Drive Monitor
- Windows Performance Monitor with PhysicalDisk counters (Correct answer)
- Acronis Backup activity log
- Windows Event Viewer Application log
Correct answer: Windows Performance Monitor with PhysicalDisk counters
Windows Performance Monitor with PhysicalDisk counters (Avg. Disk sec/Transfer, Disk Bytes/sec) directly measures disk I/O throughput and latency to identify storage bottlenecks.
Question 4: Acronis Cyber Protect reports a machine as 'offline' in the management console, but the machine is reachable via ping and RDP. What should you check first?
- Whether port 443 is open between the agent and the management server
- Whether the Acronis Managed Machine Service is running on the target machine (Correct answer)
- Whether the backup plan is currently executing on the machine
- Whether the machine's firewall is blocking ICMP packets
Correct answer: Whether the Acronis Managed Machine Service is running on the target machine
The 'offline' status in the console typically means the Acronis Managed Machine Service (MMS) is stopped or crashed, even if the machine itself is accessible via other protocols.
Question 5: During a bare-metal restore to dissimilar hardware, the restored system fails to boot. Which Acronis feature should have been used to address this?
- Acronis Universal Restore (Correct answer)
- Acronis Startup Recovery Manager
- Acronis Secure Zone
- Acronis Active Restore
Correct answer: Acronis Universal Restore
Acronis Universal Restore injects the appropriate mass storage and HAL drivers into the restored system so it can boot on hardware different from the original source machine.
Question 6: A backup of an Exchange Server database using Acronis completes successfully, but the individual mailbox granular recovery option is unavailable. What is the most likely reason?
- The Exchange VSS writer was excluded from the backup
- Granular recovery requires the Acronis Agent for Exchange to be installed separately (Correct answer)
- The backup was taken in 'disk' mode rather than 'application-aware' mode
- Exchange granular recovery requires a minimum of 3 backup versions in the archive
Correct answer: Granular recovery requires the Acronis Agent for Exchange to be installed separately
Granular mailbox-level recovery from Exchange backups requires the dedicated Acronis Agent for Microsoft Exchange to be installed alongside the standard backup agent.
Question 7: An Acronis deduplication store on a storage node is reporting degraded performance. Which maintenance operation should be performed to address fragmentation within the deduplication database?
- Run 'Validate archive' on all backup chains stored in the deduplication store
- Compact the deduplication database using the Storage Node management tools (Correct answer)
- Delete all backup versions older than 30 days to reclaim space
- Rebuild the backup catalog from the management server console
Correct answer: Compact the deduplication database using the Storage Node management tools
The deduplication database on an Acronis Storage Node becomes fragmented over time, and the Compact operation reorganizes the database to reclaim space and restore performance.
