CVAT supports Amazon S3, Azure Blob Storage, Backblaze B2 (S3-compatible) and Google Cloud Storage for importing and exporting annotation datasets.
The cloud storages page contains elements, each of them relating to a separate cloud storage.
Each element contains: preview, cloud storage name, provider, creation and update info, status,
? button for displaying the description and the actions menu.
Each button in the action menu is responsible for a specific function:
Update — update this cloud storageDelete — delete cloud storage.This preview will appear when it is impossible to get a real preview (e.g. storage is empty or invalid credentials were used).
In the upper left corner, there is a search bar, using which you can find the cloud storage by display name, provider, etc. In the upper right corner, there are {{< ilink "/docs/annotation/manual-annotation/utilities/filter#sort-by" "sorting" >}}, {{< ilink "/docs/annotation/manual-annotation/utilities/filter#quick-filters" "quick filters" >}}, and filter.
{{% alert title="Note" color="primary" %}} Applying the filter disables the {{< ilink "/docs/annotation/manual-annotation/utilities/filter#quick-filters" "quick filters" >}}. {{% /alert %}}
The filter works similarly to the filters for annotation, you can create rules from properties, {{< ilink "/docs/annotation/manual-annotation/utilities/filter#supported-operators-for-properties" "operators" >}}, and values and group rules into {{< ilink "/docs/annotation/manual-annotation/utilities/filter#groups" "groups" >}}. For more details, consult the {{< ilink "/docs/annotation/manual-annotation/utilities/filter#create-a-filter" "filter section" >}}. Learn more about {{< ilink "/docs/annotation/manual-annotation/utilities/filter#date-and-time-selection" "date and time selection" >}}.
To clear all filters, select Clear filters.
