Quotas and Accounting

Quotas

Each project has defined quota limits that determine the maximum amount of cloud resources it can use. These quotas apply to resources such as compute instances, volumes, networks, and snapshots.

Quotas can be viewed using the Openstack Horizon Dashboard or via CLI:

$ openstack quota show --fit

For the Object Storage quota (in bytes) use the command: 

openstack object store account show


$ openstack object store account show

| Objects    | 0                                     |
| properties | quota-bytes='1099511627776'           |

Info

When displaying quotas, a value of -1 or none means unlimited.

You can change your quotas from your Infomaniak workspace. quotas.png

Snapshot vs Backup Quotas

It's important to understand the difference between snapshots and backups:

  • Snapshots refer to volume-level snapshots (Cinder) — they are point-in-time copies of block storage volumes.
  • Backups refer to instance-level backups (Glance) — they typically contain entire system images.

These are tracked and limited by different quota fields:

Quota Field Resource Type Applies to
snapshots Snapshots Volumes (Cinder)
backups Backups Instances (Glance)

Snapshot Backend Types

Snapshots can be further limited per storage backend. These backend-specific quotas appear as:

  • snapshots_CEPH_1
  • snapshots_CEPH_1_perf1
  • snapshots_CEPH_1_perf2, etc.

These fields define per-backend limits. For example:

  • If snapshots = 100 and snapshots_CEPH_1_perf2 = 10, only 10 snapshots can be stored on the perf2 backend, but the total across all types must stay below 100.
  • A value of -1 in a backend-specific field means it is unlimited as long as the total snapshots quota isn't exceeded.

These values appear in CLI outputs for transparency. To summarize, the current limit is 100 snapshots in total.

Snapshot Quota Levels

We have aligned our snapshot quotas with the number of volumes allowed per level. Clients typically perform multiple snapshots per volume, so the quotas are designed to reflect that:

Level Volumes Snapshots
1 20 40
2 100 200
3 500 1000

This allows for basic snapshot rotation (e.g. one active + one backup snapshot per volume).
