Read the first 7 Veeam Backup & Replication Architecture flashcards as text

  1. In a Veeam Backup & Replication deployment, which component is responsible for cataloging VM guest OS file system metadata to enable file-level restore?

    Answer: Veeam Guest Catalog Service

    The Veeam Guest Catalog Service indexes guest OS file metadata stored in the backup catalog, enabling granular file-level restore from backup files.

  2. What is the role of the Veeam vPower NFS Service in the architecture?

    Answer: It provides an NFS datastore that allows ESXi hosts to mount VMs directly from backup files

    The vPower NFS Service presents backup files as a virtual NFS datastore so ESXi can mount and instantly power on VMs without restoring data first.

  3. When Veeam performs a backup using the Network transport mode, how is VM data transferred?

    Answer: Via the VMware VDDK over the LAN using the ESXi management network

    Network (NBD) mode uses the VMware Virtual Disk Development Kit (VDDK) API over the ESXi management network to read VM disk data across the LAN.

  4. Which Veeam component stores job configurations, restore points metadata, and session history?

    Answer: Veeam Backup Server (Microsoft SQL database)

    The Veeam Backup Server uses a Microsoft SQL (or SQL Express) database to store all configuration data including job definitions, session logs, and restore point metadata.

  5. In Scale-out Backup Repository (SOBR), what is the function of the 'Performance Tier'?

    Answer: It holds recent backups on fast storage for quick restores and active backup chains

    The Performance Tier of a SOBR consists of fast extents that store active backup chains, ensuring recent restore points are quickly accessible.

  6. How does Veeam's Changed Block Tracking (CBT) improve incremental backup performance?

    Answer: It tracks which disk blocks changed since the last snapshot, so only changed blocks are read

    CBT (via VMware's VADP) identifies and reads only the blocks that changed since the previous backup, dramatically reducing backup window and data transferred.

  7. What defines a 'backup chain' in Veeam Backup & Replication?

    Answer: A full backup file plus all subsequent incremental or reverse-incremental backup files needed to reconstruct a restore point

    A backup chain is the full backup plus all dependent incremental files required to synthesize any specific restore point in that chain.
