Troubleshooting, Performance Optimization & Support Flashcards

An Acronis backup to a cloud destination fails with 'SSL certificate verification error.' What is the most efficient resolution?

Answer: Install the required CA certificate chain in the Windows Trusted Root store on the agent machine

SSL verification failures are typically caused by a missing or untrusted CA certificate; installing the correct CA chain in the Windows Trusted Root Certification Authorities store resolves the error.

After enabling encryption on an existing Acronis backup plan, the next backup run creates a new full backup instead of an incremental. Why does this occur?

Answer: Acronis creates a new backup chain when encryption is enabled because existing unencrypted blocks cannot be extended with encrypted data

Enabling or changing encryption on a backup plan forces a new full backup because Acronis cannot create an encrypted incremental on top of an unencrypted backup chain.

A VM protected by Acronis Cyber Protect Cloud shows 'protection plan conflict' in the console. What does this status mean?

Answer: Two protection plans with conflicting backup schedules are both applied to the same machine

A 'protection plan conflict' occurs when multiple protection plans with overlapping or incompatible settings (e.g., conflicting backup windows or modules) are simultaneously applied to the same machine.

An Acronis Storage Node reports high disk latency on its deduplication store volume. Which diagnostic step identifies whether the issue is hardware or software?

Answer: Temporarily disable deduplication and measure raw backup write throughput to the same volume

Temporarily disabling deduplication and measuring raw write throughput isolates whether the latency is caused by the deduplication algorithm overhead or by the underlying hardware.

A backup technician needs to verify that an Acronis backup archive is not corrupted before a planned disaster recovery exercise. Which operation should be run?

Answer: Run 'Validate archive' against the backup chain to verify checksums

The 'Validate archive' operation in Acronis calculates and verifies checksums for all backup data blocks, confirming the archive is intact and recoverable.

When using Acronis Instant Restore to run a VM directly from backup, users report the VM is unusably slow. What is the expected behavior and its cause?

Answer: Performance is degraded while background migration moves VM data from the backup archive to the production datastore; it improves as data migrates

During Instant Restore, each disk block is read from the backup archive on demand; performance improves progressively as background hydration migrates blocks to the production datastore.

An Acronis Agent for VMware (Virtual Appliance) cannot communicate with the vCenter Server after a vCenter certificate renewal. What must be done to restore communication?

Answer: Re-register the Virtual Appliance with vCenter using the updated certificate fingerprint

After vCenter certificate renewal, the stored certificate fingerprint used by the Acronis Virtual Appliance becomes invalid and must be updated by re-registering the appliance with vCenter.
