Mejor estrategia para respaldar un file server de Windows con 20 TB

Hi@tavoli - did you reach out to Veeam Support? They are your best source to help out.

What kind of backup are you running? NAS/File Share? What does the Backup Job task list say your bottleneck is? Do you have your target Repository configured for Fast Clone? This should make your GFS files get created extremely fast. Also, what Veeam version & product are you using? Please provide much more detail and we can try to assist. But, it's also your best bet to reach out to Support.

Best.

Hi ​@tavoli 
First of all, you're lucky to be using a future operating system like Windows 2029 (I know that was just a typo). 🤣
It's normal for standard, and bigger, VM backup to be slow, even if you are using a physical server connected to the SAN. 
I can suggest two approaches.

The first is what ​Shane suggested: add the servers as shares and back them in that way (using a general-purpose proxy).

The second option, if your SAN can do it, is to enable a storage snapshot. This will reduce the load on the virtual infrastructure and make backups faster.

Please check official documentation for those two solution.

My 2 cents

Hi ​@tavoli ,

What backup transport mode are you currently using (Direct SAN, Virtual Appliance, or Network mode / NBD)?
If you are using Network mode, it may be worth evaluating the other transport options, as they can significantly improve backup performance.

Backing up the file shares directly could be an alternative. However, please note that this approach may lead to higher licensing costs, as it requires an additional VUL for every 500 GB of data, or alternatively, a dedicated capacity-based license.

Regarding GFS retention: this is expected behavior. GFS restore points are additional full backups that are stored on the repository, which naturally results in increased storage consumption.

Hola!

aquí veo varias cosas. 
puedes pasarnos un dibujo de tu arquitectura?

como te han preguntado, van por SAN?, VSAN, cabina NFS?

el foco es distinto, depende de tu red, si es de 1gbps, 10gbps o más, si el destino es HDD, híbrido, nvme, 

por el tema de uso de almacenamiento del GFS, el destino podría ser un appliance con de duplicación, así, ahorrarías en espacio.

nos vas contando,

un abrazo
