Quotas & limits

This page describes quotas and request limits for Backup and DR. You can request increases to quotas, but limits cannot be adjusted. Quotas and limits are subject to change.

Backup and DR quotas define the number of resources that your project has access to. These quotas represent resource counts (such as the number of backup vaults or backups), and not storage capacity (such as gigabytes or terabytes).

Backup and DR resource quotas are available for both regional and multi-regional backups. Quotas are enforced at the project and backup vault level. Default quota values (such as STANDARD or HIGH) are determined by the reputation tier of your project or billing account.
