# nebius_storage_v1alpha1_transfer data source
#### Retrieving the Data Source
This data source can be retrieved by one of ID or name.
##### Retrieve by ID
To retrieve by ID, fill in only the `id` field:
```hcl theme={null}
data ... {
id = "your-ID"
}
```
##### Retrieve by Name
To retrieve by name, fill in only the `name` and `parent_id` fields:
```hcl theme={null}
data ... {
name = "your name"
parent_id = "data-source-parent-id"
}
```
## Schema
### Optional
* `id` (String) Identifier for the resource, unique for its resource type.
* `name` (String) Human readable name for the resource.
* `parent_id` (String) Identifier of the parent resource to which the resource belongs.
### Read-Only
* `after_n_empty_iterations` (Attributes) *Cannot be set alongside after\_one\_iteration or infinite.* (see [below for nested schema](#nestedatt--after_n_empty_iterations))
* `after_one_iteration` (Attributes) *Cannot be set alongside after\_n\_empty\_iterations or infinite.* (see [below for nested schema](#nestedatt--after_one_iteration))
* `created_at` (String) :
Timestamp indicating when the resource was created.
A string representing a timestamp in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format: `YYYY-MM-DDTHH:MM:SSZ` or `YYYY-MM-DDTHH:MM:SS.SSS±HH:MM`
* `destination` (Attributes) (see [below for nested schema](#nestedatt--destination))
* `infinite` (Attributes) :
Infinite transfers do not stop automatically and can be stopped manually by the user.
*Cannot be set alongside after\_one\_iteration or after\_n\_empty\_iterations.* (see [below for nested schema](#nestedatt--infinite))
* `inter_iteration_interval` (String) :
Time to wait between transfer iterations. Default is 15 minutes if not specified.
Duration as a string: possibly signed sequence of decimal numbers, each with optional fraction and a unit suffix, such as `300ms`, `-1.5h` or `2h45m`. Valid time units are `ns`, `us` (or `µs`), `ms`, `s`, `m`, `h`, `d`.
* `labels` (Map of String) Labels associated with the resource.
* `metadata` (Attributes) :
#### Inner value description
Common resource metadata. (see [below for nested schema](#nestedatt--metadata))
* `overwrite_strategy` (String) :
Overwrite strategy set logic of overwrite already existed objects in destination bucket.
#### Supported values
Possible values:
* `OVERWRITE_STRATEGY_UNSPECIFIED`
* `NEVER`:
Never overwrite objects that exist in the destination.
If object exists in destination bucket, skip it.
Safest option to prevent data loss.
* `IF_NEWER`:
Overwrite only if source object is newer than destination.
Comparison based on Last-Modified timestamp.
Recommended for incremental sync scenarios.
* `ALWAYS`:
Always overwrite destination objects unconditionally.
Use with caution - may cause data loss in destination.
Suitable for full bucket synchronization.
* `resource_version` (Number) :
Version of the resource for safe concurrent modifications and consistent reads.
Positive and monotonically increases on each resource spec change (but *not* on each change of the
resource's container(s) or status).
Service allows zero value or current.
* `source` (Attributes) (see [below for nested schema](#nestedatt--source))
* `status` (Attributes) (see [below for nested schema](#nestedatt--status))
* `updated_at` (String) :
Timestamp indicating when the resource was last updated.
A string representing a timestamp in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format: `YYYY-MM-DDTHH:MM:SSZ` or `YYYY-MM-DDTHH:MM:SS.SSS±HH:MM`
### Nested Schema for `after_n_empty_iterations`
Read-Only:
* `empty_iterations_threshold` (Number) Number of consecutive iterations with zero transferred objects required to stop transfer.
### Nested Schema for `after_one_iteration`
### Nested Schema for `destination`
Read-Only:
* `bucket_name` (String)
* `endpoint` (String) :
The endpoint must be in the form of a URL, starting with the protocol (https),
followed by the endpoint address without a trailing slash.
Example: [https://storage.us-central1.nebius.cloud](https://storage.us-central1.nebius.cloud)
* `prefix` (String) :
Prefix to add to the beginning of each transferred object key in the destination bucket.
During transfer, the resulting object key in the destination bucket is computed
by removing source.prefix (if provided) from the original key and then prepending destination.prefix.
Important: This transformation may result in an empty object key or one that exceeds allowed length limits.
Use prefixes that guarantee valid resulting object keys for your objects after transformation.
* `region` (String)
### Nested Schema for `infinite`
### Nested Schema for `metadata`
### Nested Schema for `source`
Read-Only:
* `bucket_name` (String)
* `endpoint` (String) :
The endpoint must be in the form of a URL, starting with the protocol (https),
followed by the endpoint address without a trailing slash.
Example: [https://storage.us-central1.nebius.cloud](https://storage.us-central1.nebius.cloud)
* `limiters` (Attributes) :
Limiters applied to source bucket operations. These limits include all operations
required for transfer (HeadObject, GetObject, ListObjects). For details about
which operations are used, see public documentation: [http://docs.nebius.com/object-storage/transfer/quickstart#background](http://docs.nebius.com/object-storage/transfer/quickstart#background).
Note: Since the service performs comparable request volumes and data transfers
to both source and destination, these limits will indirectly constrain
destination operations as well. (see [below for nested schema](#nestedatt--source--limiters))
* `prefix` (String) :
Prefix to filter objects in the source bucket. Only objects whose keys start with this prefix will be transferred.
During transfer, the resulting object key in the destination bucket is computed
by removing source.prefix from the original key and then prepending destination.prefix (if provided).
Important: This transformation may result in an empty object key or one that exceeds allowed length limits.
Use prefixes that guarantee valid resulting object keys for your objects after transformation.
* `region` (String)
### Nested Schema for `source.limiters`
Read-Only:
* `bandwidth_bytes_per_second` (Number) Maximum bandwidth in bytes per second. If set to zero, default limit will be applied.
* `requests_per_second` (Number) Maximum number of requests per second. If set to zero, default limit will be applied.
### Nested Schema for `status`
Read-Only:
* `error` (String) Error information if the transfer has failed.
* `last_iteration` (Attributes) (see [below for nested schema](#nestedatt--status--last_iteration))
* `state` (String) :
#### Supported values
Possible values:
* `STATE_UNSPECIFIED`
* `ACTIVE`
* `STOPPING`
* `STOPPED`
* `FAILING`
* `FAILED`

* `error` (String) Human-readable error description. Populated only if state is FAILED.
* `objects_discovered_count` (Number)
* `objects_migrated_count` (Number)
* `objects_migrated_size` (Number)
* `objects_skipped_count` (Number)
* `sequence_number` (Number)
* `start_time` (String) A string representing a timestamp in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format: `YYYY-MM-DDTHH:MM:SSZ` or `YYYY-MM-DDTHH:MM:SS.SSS±HH:MM`
