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

  1. What is Veeam's 'Immutable Backup' feature and which repository type supports it natively in Veeam v12?

    Answer: Immutable backups cannot be modified or deleted for a set period; supported on Linux hardened repositories using immutable flag (chattr +i) and S3-compatible object storage with object lock

    Veeam supports immutability on Linux hardened repositories (using OS-level immutable flags without root SSH access) and S3 object storage with Object Lock, protecting backups from ransomware deletion.

  2. In Veeam's architecture, what is a 'Hardened Repository' and what makes it secure?

    Answer: A Linux-based backup repository configured so that Veeam connects via a single-use credential with no persistent SSH access, and backup files are made immutable

    The hardened repository uses a Linux OS where Veeam elevates privileges only temporarily during deployment, then revokes SSH access — combined with immutable file flags, this prevents backup deletion even if credentials are compromised.

  3. What is Veeam's 'Capacity Tier' in a Scale-out Backup Repository used for, and which storage types are supported?

    Answer: Long-term retention of older backup data offloaded from Performance Tier extents; supports S3-compatible object storage, Azure Blob, Google Cloud Storage, and IBM Cloud Object Storage

    The Capacity Tier automatically offloads older backup data from fast Performance Tier extents to cost-effective object storage, with support for major cloud and on-premises S3-compatible platforms.

  4. How does Veeam handle backup of VMs with large disks efficiently using 'Parallel Processing'?

    Answer: Veeam can simultaneously read multiple VM disks in parallel using separate data streams, reducing total backup time for multi-disk VMs

    Parallel processing allows Veeam to open multiple concurrent read streams for different VM disks simultaneously, significantly reducing backup windows for VMs with many or large disks.

  5. In Veeam's replication architecture, what is a 'Replica Seeding' and when would you use it?

    Answer: Pre-populating a replica at the DR site using a backup transported via physical media (ship-and-seed), then synchronizing only incremental changes over WAN — used when initial full replication over WAN is impractical

    Replica seeding allows the initial large dataset to be transported physically to the DR site, after which Veeam only needs to synchronize incremental changes over the WAN link.

  6. What Veeam technology enables 'SureBackup' jobs to verify backup recoverability, and how does it work?

    Answer: SureBackup uses a Virtual Lab (isolated network sandbox) to automatically power on backed-up VMs from backup files and run verification scripts to confirm they boot and applications respond

    SureBackup starts VMs directly from backup files in an isolated Virtual Lab environment, runs VMware Tools heartbeat checks and optional custom scripts to verify each VM boots successfully and applications are functional.

  7. Which Veeam feature allows a backup administrator to restore a VM to any point in time between scheduled backups using journal-based recovery?

    Answer: Veeam Continuous Data Protection (CDP) with near-zero RPO replication using VMware vSphere APIs for I/O filtering

    Veeam CDP uses VMware vSphere APIs for I/O Filtering (VAIO) to capture every write to VM disks in real time, enabling recovery to any second within the retention window — far beyond scheduled backup granularity.
