                           [--timeout]. The 1th example of the child command would be to use it to 'copy a blob asynchronously  use  az storage blob show  to check the status of the blobs', the syntax is: az storage blob copy start --account-key 00000000 --account-name MyAccount --destination-blob MyDestinationBlob --destination-container MyDestinationContainer --source-uri https://storage.blob.core.windows.net/photos. The 2th example of the child command would be to use it to 'copy a blob asynchronously  use  az storage blob show  to check the status of the blobs', the syntax is: az storage blob copy start --account-name MyAccount --destination-blob MyDestinationBlob --destination-container MyDestinationContainer --sas-token $sas --source-uri https://storage.blob.core.windows.net/photos. The parameter '--destination-blob -b' is required. It is used to name of the destination blob. if it exists, it will be overwritten.. The parameter '--destination-container -c' is required. It is used to the container name.. The parameter '--account-key' is optional. storage account key. must be used in conjunction with storage account name. environment variable: azure_storage_key.. The parameter '--account-name' is optional. storage account name. related environment variable: azure_storage_account. must be used in conjunction with either storage account key or a sas token. if neither are present, the command will try to query the storage account key using the authenticated azure account. if a large number of storage commands are executed the api quota may be hit.. The parameter '--auth-mode' is optional. the mode in which to run the command. "login" mode will directly use your login credentials for the authentication. the legacy "key" mode will attempt to query for an account key if no authentication parameters for the account are provided. environment variable: azure_storage_auth_mode.. The parameter '--blob-endpoint' is optional. storage data service endpoint. must be used in conjunction with either storage account key or a sas token. you can find each service primary endpoint with `az storage account show`. environment variable: azure_storage_service_endpoint.. The parameter '--connection-string' is optional. storage account connection string. environment variable: azure_storage_connection_string.. The parameter '--destination-blob-type' is optional. defines the type of blob at the destination. value of "detect" determines the type based on source blob type.. The parameter '--destination-if-match' is optional. an etag value, or the wildcard character (*). specify this header to perform the operation only if the resource's etag matches the value specified.. The parameter '--destination-if-modified-since' is optional. a datetime value. azure expects the date value passed in to be utc. if timezone is included, any non-utc datetimes will be converted to utc. if a date is passed in without timezone info, it is assumed to be utc. specify this conditional header to copy the blob only if the destination blob has been modified since the specified date/time. if the destination blob has not been modified, the blob service returns status code 412 (precondition failed).. The parameter '--destination-if-none-match' is optional. an etag value, or the wildcard character (*). specify this header to perform the operation only if the resource's etag does not match the value specified. specify the wildcard character (*) to perform the operation only if the resource does not exist, and fail the operation if it does exist.. The parameter '--destination-if-unmodified-since' is optional. a datetime value. azure expects the date value passed in to be utc. if timezone is included, any non-utc datetimes will be converted to utc. if a date is passed in without timezone info, it is assumed to be utc. specify this conditional header to copy the blob only if the destination blob has not been modified since the specified date/time. if the destination blob has been modified, the blob service returns status code 412 (precondition failed).. The parameter '--destination-lease-id' is optional. the lease id specified for this header must match the lease id of the estination blob. if the request does not include the lease id or it is not valid, the operation fails with status code 412 (precondition failed).. The parameter '--destination-tags-condition' is optional. specify a sql where clause on blob tags to operate only on blobs with a matching value.. The parameter '--metadata' is optional. metadata in space-separated key=value pairs. this overwrites any existing metadata.. The parameter '--rehydrate-priority -r' is optional. indicate the priority with which to rehydrate an archived blob.. The parameter '--requires-sync' is optional. enforce that the service will not return a response until the copy is complete.. The parameter '--sas-token' is optional. a shared access signature (sas). must be used in conjunction with storage account name. environment variable: azure_storage_sas_token.. The parameter '--source-account-key' is optional. the storage account key of the source blob.. The parameter '--source-account-name' is optional. the storage account name of the source blob.. The parameter '--source-blob' is optional. the blob name for the source storage account.. The parameter '--source-container' is optional. the container name for the source storage account.. The parameter '--source-if-match' is optional. an etag value, or the wildcard character (*). specify this header to perform the operation only if the resource's etag matches the value specified.. The parameter '--source-if-modified-since' is optional. a datetime value. azure expects the date value passed in to be utc. if timezone is included, any non-utc datetimes will be converted to utc. if a date is passed in without timezone info, it is assumed to be utc. specify this conditional header to copy the blob only if the source blob has been modified since the specified date/time.. The parameter '--source-if-none-match' is optional. an etag value, or the wildcard character (*). specify this header to perform the operation only if the resource's etag does not match the value specified. specify the wildcard character (*) to perform the operation only if the resource does not exist, and fail the operation if it does exist.. The parameter '--source-if-unmodified-since' is optional. a datetime value. azure expects the date value passed in to be utc. if timezone is included, any non-utc datetimes will be converted to utc. if a date is passed in without timezone info, it is assumed to be utc. specify this conditional header to copy the blob only if the source blob has not been modified since the specified date/time.. The parameter '--source-lease-id' is optional. specify this to perform the copy blob operation only if the lease id given matches the active lease id of the source blob.. The parameter '--source-path' is optional. the file path for the source storage account.. The parameter '--source-sas' is optional. the shared access signature for the source storage account.. The parameter '--source-share' is optional. the share name for the source storage account.. The parameter '--source-snapshot' is optional. the blob snapshot for the source storage account.. The parameter '--source-tags-condition' is optional. specify a sql where clause on blob tags to operate only on blobs with a matching value.. The parameter '--source-uri -u' is optional. a url of up to 2 kb in length that specifies an azure file or blob. the value should be url-encoded as it would appear in a request uri. if the source is in another account, the source must either be public or must be authenticated via a shared access signature. if the source is public, no authentication is required. examples: `https://myaccount.blob.core.windows.net/mycontainer/myblob`, `https://myaccount.blob.core.windows.net/mycontainer/myblob?snapshot=<datetime>`, `https://otheraccount.blob.core.windows.net/mycontainer/myblob?sastoken`.. The parameter '--tags' is optional. space-separated tags: key[=value] [key[=value] ...]. tags are case-sensitive. the tag set may contain at most 10 tags.  tag keys must be between 1 and 128 characters, and tag values must be between 0 and 256 characters. valid tag key and value characters include: lowercase and uppercase letters, digits (0-9), space (` `), plus (+), minus (-), period (.), solidus (/), colon (:), equals (=), underscore (_).. The parameter '--tier' is optional. the tier value to set the blob to. for page blob, the tier correlates to the size of the blob and number of allowed iops. possible values are p10, p15, p20, p30, p4, p40, p50, p6, p60, p70, p80 and this is only applicable to page blobs on premium storage accounts; for block blob, possible values are archive, cold, cool and hot. this is only applicable to block blobs on standard storage accounts.. The parameter '--timeout' is optional. request timeout in seconds. applies to each call to the service..
