To design a solution that meets the needs and requirements of Veeam University Hospital, you need to gather some information during the discovery phase. This information will help you to understand the current state of the environment, the goals and expectations of the stakeholders, and the constraints and challenges of the project.

According to the Veeam Backup & Replication Best Practice Guide1, some of the information that is necessary for designing a solution and must be gathered during discovery are:

* Operating systems used to run the workloads. This information will help you to determine the compatibility and supportability of the workloads with Veeam products and features, as well as the licensing and configuration requirements.

* Allowed backup windows. This information will help you to plan and schedule the backup jobs according to the availability and performance of the workloads, as well as the service level agreements (SLAs) and recovery point objectives (RPOs) of the organization.

* Amount of used disk space. This information will help you to estimate the backup storage requirements, as well as the backup compression and deduplication ratios, based on the type and size of the data.

The Veeam backup method that should be used for the virtualized stock trading application is to separate the virtual machine into its own job and enable application aware processing.This method allows Veeam Backup & Replication to create transactionally consistent backups of the application, by quiescing the application and creating a snapshot of its data1. This ensures that the application can be restored to a working state, without data loss or corruption.The other options are either not suitable for the application (option A, as Veeam agent is designed for physical machines or cloud instances2), not sufficient for the application (option C, as pre-freeze and post-thaw scripts do not guarantee transactional consistency3), or not related to the backup method (option D, as replication is a different process from backup).Reference:Application-Aware Processing,Veeam Agent Management,Pre-Freeze and Post-Thaw Scripts, [Replication].

The retention requirement for gold tier virtual machines is that they must have 14 daily, eight weekly, three monthly and seven yearly backups. This requirement can be derived from the technical requirement of having eight weekly backups, three monthly backups, and seven yearly backups for regulatory purposes, as well as the business requirement of having daily backups for gold tier virtual machines.

Snapshot stun is a phenomenon that occurs when a VMware snapshot is removed and the virtual machine (VM) experiences a temporary freeze or performance degradation1. This can affect the availability and consistency of mission critical applications running on the VM.

To avoid snapshot stun, Veeam Backup & Replication offers several options for backing up Linux VMs, such as backup from storage snapshots, direct SAN access, or hot-add2. However, based on the business requirements, the best option is to run pre-freeze and post-thaw scripts before backing up the workload.

Pre-freeze and post-thaw scripts are custom scripts that you can configure to run on the Linux VM before and after the snapshot is taken. The pre-freeze script can be used to quiesce the application and flush its data to disk, ensuring a consistent backup.The post-thaw script can be used to resume the application and perform any necessary cleanup actions3.

By using pre-freeze and post-thaw scripts, you can achieve application consistency and minimize the impact of snapshot stun on the Linux VM.You can use the Veeam Backup & Replication user interface or the Veeam PowerShell snap-in to configure the scripts for the backup job3.

Snapshot Stun Issue

To design a solution that meets the requirements for off-site immutable backups for Veeam University Hospital, you need to consider some of the options and features that Veeam products and features offer. This will help you to ensure the security and integrity of your backup data, as well as the compatibility and supportability of the cloud provider that does not currently support immutability.

According to the Veeam Backup & Replication Best Practice Guide, immutability is a feature that prevents backup files from being deleted or modified by anyone until the specified retention period expires. Immutability can be achieved by using S3 Object Lock or Hardened Repository, which are two different solutions that Veeam Backup & Replication supports.

Based on this definition, the best option to still satisfy the requirements for off-site immutable backups is A. Backup copy to a hardened repository.

This option means that:

* The backup copy is a type of job that allows you to create and maintain copies of your backup data on a secondary backup repository. You can use backup copy jobs to send your backup data off-site, as well as to apply different retention settings and policies.

* The hardened repository is a solution that allows you to add a hardened repository based on a Linux server to your backup infrastructure. You can use hardened repository with Veeam Backup & Replication to make your backups immutable on-premises or off-site.

* The backup copy to a hardened repository can be configured and managed by Veeam Backup & Replication, regardless of the cloud provider that does not currently support immutability. You only need to deploy and connect a Linux server with a hardened repository in the cloud environment, and then use it as a target for your backup copy jobs.
