Backup Repository

Veeam Backup for Google Cloud compresses all backed-up data when saving it to a backup repository. The compression rate depends on the type and structure of source data and usually varies from 50% to 60%. This means that the compressed data typically consumes 50% less storage space than the source data.

Parameter	Value
Average size of backed-up data	40%–50% of source data
Compression rate	50%–60%

Object Sizes

Depending on whether you choose to keep backed-up data in short-term or long-term storage, Veeam Backup for Google Cloud saves different objects to Google Cloud storage buckets.

Object Type	Block Size
Backup data (Standard)	1 MB (compressed to ~512 KB)
Backup data (Archive)	512 MB
Metadata	4 KB (per 1 GB of VM source data)

Storage Bucket Placement

To achieve best performance, create backup repositories in regional storage buckets and place them in the same region as source instances. A situation where a storage bucket is located far from a source instance may cause slow network throughput between regions.

Cost Estimation

Veeam Backup for Google Cloud comes with a built-in cost calculator that allows you to estimate your Google Cloud expenses. It uses publicly available Google Cloud price lists, so it may not reflect your exact cost in case of custom pricing or an enterprise agreement. Full details can be found at the cost estimation step of the Add Policy wizard.
