What are the system requirements for CubeBackup?

Hardware requirements


No less than 6GB. 8GB is recommended.


3 types backup storage are supported:

  • Local hard disk
  • NAS, SAN, or other network storage media
  • Cloud storage on Amazon S3, Google Cloud, Azure Blob Storage, Wasabi and Backblaze B2

The amount of storage required depends, of course, on how much data needs to be backed up, but here are a few general guidelines that we can offer:

  • CubeBackup stores a complete version history of all files and folders. On average, this will make backup sizes about 40% larger, across all files.

  • Since new data is being continually generated on your Google Workspace domain, be sure to leave lots of room for growth. Generally, backup storage space should be double the size of your current Google Workspace data.

  • If you are using private cloud storage as the backup location, there is no need to worry about size limitations.

Internet connection:

The bandwidth of your Internet connection is recommended to be at least 50Mbps.
