To better understand how to calculate the hardware configuration for backup storage with the NFS share destination, consider the following example with RAM and CPU reservations.
If you have 1 node (1 system+metadata disk and 1 storage disk) and want to use it for backup storage, refer to the table below for the calculations.
|Service||The only node|
|System||4.5 GB, 3.3 cores|
1 storage disk1, 1 metadata on system disk (each takes 0.5 GB and 0.2 cores), that is 1 GB and 0.4 cores in total
|Backup Gateway||1 GB, 0.5 cores|
|Service reservations||6.5 GB of RAM and 4.2 cores|
|Minimum hardware configuration||8 GB of RAM and 4 cores|
|Recommended hardware configuration||8 GB of RAM and 6 cores|
