What are the system requirements for CubeBackup for Google Workspace?

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, Backblaze B2 and other S3 compatible storage

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:

  • Minimum 10 GB available for local data index (data index size will expand based on the number of backup users).

  • 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.

Internet connection

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