Backup Infrastructure and Repositories Flashcards

Which Veeam component is responsible for processing backup jobs and writing data to the backup repository?

Answer: Backup Proxy

The Backup Proxy processes VM data from the source and sends it to the backup repository, offloading this work from the backup server.

What is the default port used for communication between Veeam Backup & Replication components?

Answer: 2500-3300

Veeam uses ports 2500-3300 as the default data transmission range between backup infrastructure components.

Which repository type in Veeam provides the highest performance for deduplication by storing data in a proprietary format?

Answer: Deduplicating storage appliance

Deduplicating storage appliances (such as EMC Data Domain or HPE StoreOnce) use native deduplication in a proprietary format for high efficiency.

In Veeam, what happens when a backup repository runs out of free space during an active backup job?

Answer: The job fails immediately

When a repository runs out of free space, the active backup job fails because Veeam cannot complete writing the backup data.

Which Veeam feature allows you to store backup metadata separately from backup data files?

Answer: Veeam Catalog

The Veeam Catalog stores indexing and guest file system metadata separately, enabling fast file-level search and restore.

When configuring a Linux-based backup repository, which file system is recommended for best performance with Veeam?

Answer: XFS

XFS is the recommended file system for Linux backup repositories because it supports fast cloning operations used by Veeam's synthetic full backups.

What is the purpose of the 'Per-VM backup files' option in a Veeam backup repository?

Answer: Stores each VM's backup chain in individual files

Per-VM backup files stores each virtual machine's backup chain in separate files, enabling parallel processing and reducing restore time.
