This page describes how pricing and billing of backups per GB was introduced in Abiquo 6.1.
For full details of backup pricing, please see https://abiquo.atlassian.net/wiki/spaces/doc/pages/311362596/Create+a+new+pricing+model#Backup-prices
In Abiquo 6.1, you can activate the Backup GB usage in the platform in Configuration view on the Billing tab, as for other usage types.
The platform obtains backup details from the backup system. In this initial version, Abiquo supports Backup GB for Veeam.
If you have prices for Backup GB in the enterprise pricing model, then Abiquo will create billing data for this usage.
To generate the backup billing data, the platform sums the total storage occupied by the backup (from the backup system), divides by time that the backup is valid (not expired), and then applies the price of Backup GB.
