* Backup copy jobs with GFS enabled. This type of job does not support using immutability from S3 Object Lock because it uses synthetic full backups, which require modifying existing backup files. Synthetic full backups are not compatible with immutability settings, as they violate the principle of not changing the backup files.

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 information that is missing from discovery is what the available bandwidth is between Fresno and Carson City. This information is important for designing and sizing the backup copy jobs that need to run daily between the two sites. The available bandwidth can affect the backup copy performance, duration, and size. For example, you can use the available bandwidth to estimate how much data can be transferred between the sites within the backup copy window. You can also use the available bandwidth to determine whether you need to use compression, deduplication, or WAN acceleration to optimize the backup copy traffic.

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.

You can find more information about pre-freeze and post-thaw scripts and how to use them in the following resources:

Snapshot Stun Issue

The steps that should be taken to correct the storage configuration based on the customer's hardening requirements are to add hardened repositories to each Scale-out Backup Repository and evacuate the data from the CIFS extents. A hardened repository is a type of backup repository that provides immutability and ransomware protection for backup files by using Linux XFS file system features and Linux access control mechanisms. A Scale-out Backup Repository is a logical entity that groups several backup repositories into one pool of storage. A CIFS extent is a type of backup repository that uses a shared folder on a Windows or Linux server as a backup target. By adding hardened repositories to each Scale-out Backup Repository, you can ensure that your backups are secure, compliant, and efficient. By evacuating the data from the CIFS extents, you can remove the risk of ransomware infection or deletion of your backups.
