What are snapshot used for?
Snapshots are generally created for data protection, but they can also be used for testing application software and data mining. A storage snapshot can be used for disaster recovery (DR) when information is lost due to human error.
What is backup proxy?
A backup proxy is an architecture component that sits between the backup server and other components of the backup infrastructure. While the backup server administers tasks, the proxy processes jobs and delivers backup traffic.
How do I configure backup from storage snapshots?

How many Veeam Backup proxies do I need?
For a physical server, it is recommended to install dual CPUs with 8 cores each. For virtual proxy servers, it is recommended to configure multiple proxies with maximum 8 vCPUs to avoid co-stop scheduling issues.
How does a snapshot work?
When you take a snapshot, the metadata recording where each block of data is stored is copied to the snapshot. Then every block of data is as it was at the time the snapshot was taken. And since your files are made up of blocks of data, every file is now as it was when the snapshot was taken.
What is snapshot picture?

Do I need a Veeam proxy?
Yes, proxy server is installed as a part of Veeam B&R installation and depending on the size and configuration of your environment it could be enough to use just this default proxy server. Basically, if you meet your backup window, then there are no reasons to have additional proxies.
What is the difference between a snapshot and a backup?
Backup can be stored in another location, same server, or even the same drive in this case. Snapshots can be stored only in the same location where original data is present. Backup comprises of only file system. Snapshots comprises of different types of systems like the files, software, and settings of that type.
What is Veeam storage snapshots?
Backup from Storage Snapshots lets you speed up backup and replication for VMware vSphere VMs whose disks are hosted on storage systems. When you perform Backup from Storage Snapshots, Veeam Backup & Replication leverages storage snapshots for VM data processing.
What do Veeam proxies do?
Veeam proxy is one of the main components of Veeam Backup and replication. Veeam proxy sits between the data source and target and is used to process jobs and deliver backup traffic. It allows to offload the Veeam Backup Server and have better performance resulting shorter backup window.
What exactly is a snapshot?
In computer systems, a snapshot is the state of a system at a particular point in time. The term was coined as an analogy to that in photography. It can refer to an actual copy of the state of a system or to a capability provided by certain systems.
How does a backup proxy work in a NAS backup?

For more information about using a backup proxy in NAS backup, see NAS Backup Support. Depending on your backup architecture, a backup proxy can use one of the following data transport modes:
Where does the proxy sit in the backup server?

When to use snapshot replication in SQL Server?

SQL Server Snapshot replication takes a snapshot until a specific time on the Publisher server and applies to the Subscriber server. Database records do not change frequently.
How does a backup proxy work in vSphere?
A machine used as a backup proxy should have direct access to the storage on which VMs reside or the storage where VM data is written. This way, the backup proxy will retrieve data directly from the datastore, bypassing LAN. The backup proxy can be a VM with HotAdd access to VM disks on the datastore.
