VMCE Veeam Backup & Replication Architecture 5

Question 1

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

Accepted 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

Answer

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.

Question 2

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

Accepted 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

Answer

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.

Question 3

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

Accepted 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

Answer

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.

Question 4

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

Accepted Answer

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

Answer

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.

Question 5

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

Accepted 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

Answer

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.
