Data Migration - Snowball family

Data Migration

Snowball family
-         Rule of thumb - don’t use if data transfer over a line takes less a week or of total data size is less than 10 TB (Terabyte - a unit of information equal to one million million (1012) or, strictly, 2 to the power of 40 bytes.)

Snowball
-         50/80(US) TB appliance, data transfer solution
-         Usually cheaper than transfer over high speed internet
-         256-bit encryption
-         One-to-one device-job relationship. If data size is too large, split into multiple jobs
-         Each imported file will become an S3 object, each folder will appear as a file prefix (can’t have subfolders on S3)
-         Export – AWS takes care of saving data onto the devices and packaging up

Snowball Edge
-         100 TB, encrypted
-         Features fast network interfaces – up to 100GB/s
