Uploading an Object

Function

You can use this command to upload one or more local files or folders to a specified path in OBS. These files can be texts, images, videos, or any other type of files.

Do not change the local file or folder when uploading it. Otherwise, the upload may fail or data may be inconsistent.

Restrictions

obsutil has restrictions on the size of files or folders to be uploaded. You can upload an empty file or folder of 0 bytes. You can also upload a single file or folder with a maximum size of 5 GB in normal mode or a single file with a maximum size of 48.8 TB in multipart mode.

Parameter Description

Parameter	Optional or Mandatory	Description
file_url	Optional for uploading multiple files/folders Mandatory for uploading a file	Local file path NOTE: Do not nest paths when uploading multiple files/folders. For example, you cannot specify /a/b/c and /a/b/ at the same time. If this parameter is configured when uploading multiple files/folders, msm must be set to 1. In this case, use commas (,) to separate multiple file paths, for example, file_url1,file_url2. Files and folders can both be included when uploading multiple files/folders. For example, file_url1,folder_url1,file_url2,folder_url2.
folder_url	Optional for uploading multiple files/folders Mandatory for uploading a folder	Local folder path NOTE: If flat is not configured when uploading a folder, the entire folder is uploaded. If flat is configured, all files in the folder are uploaded. Do not nest paths when uploading multiple files/folders. For example, you cannot specify /a/b/c and /a/b/ at the same time. If this parameter is configured when uploading multiple files/folders, msm must be set to 1. In this case, use commas (,) to separate multiple folder paths, for example, folder_url1,folder_url2. Files and folders can be included when uploading multiple files/folders. For example, file_url1,folder_url1,file_url2,folder_url2.
filelist_url	Optional for uploading multiple files/folders	Indicates the path of the file that contains the list of files/folders to be uploaded. If this parameter is configured, msm must be set to 2. NOTE: The list file is in common text file formats, such as TXT and CSV. Each line in the file indicates a file or folder to be uploaded. For example: file_url1 file_url2 folder_url1 folder_url2 Do not nest paths in the list file. For example, you cannot specify /a/b/c and /a/b/ at the same time.
bucket	Mandatory	Bucket name
key	Optional	Indicates the object name or object name prefix specified when uploading a file, or the object name prefix specified when uploading a folder. The rules are as follows: If this parameter is left blank when uploading a file, the file is uploaded to the root directory of the bucket and the object name is the file name. If the value ends with a slash (/), the value is used as the object name prefix when the file is uploaded, and the object name is the value plus the file name. If the value does not end with a slash (/), the file is uploaded with the value as the object name. If this parameter is left blank when uploading a folder, the folder is uploaded to the root directory of the bucket. If the value ends with a slash (/), the value is used as the object name prefix of the folder to be uploaded. If the value does not end with a slash (/), the folder to be uploaded is prefixed with the value plus a slash (/). NOTE: For details about how to use this parameter, see Upload.
fr	Optional for uploading a file (additional parameter)	Generates an operation result list when uploading a file.
flat	Optional for uploading a folder or multiple files/folders (additional parameter)	Uploads all files in a folder but not the folder itself.
arcDir	Optional (additional parameter)	Path to which the uploaded files are archived
dryRun	Optional (additional parameter)	Conducts a dry run.
link	Optional (additional parameter)	Uploads the actual path of the symbolic-link file/folder NOTICE: If this parameter is not specified and the file to be uploaded is a symbolic-link file whose target file does not exist, the exception message "The system cannot find the file specified" will be displayed in Windows OS, while the exception message "No such file or directory" will be displayed in macOS or Linux OS. Avoid the symbolic link loop of a folder, otherwise, the upload will exit due to panic. If you do not want the system to panic, set panicForSymbolicLinkCircle to false in the configuration file.
u	Optional (additional parameter)	Indicates incremental upload. If this parameter is set, each file can be uploaded only when it does not exist in the bucket, its size is different from the namesake one in the bucket, or it has the latest modification time.
vlength	Optional (additional parameter)	After the upload completes, check whether the sizes of the objects in the bucket are the same as those of the local files.
vmd5	Optional (additional parameter)	After the upload completes, check whether the MD5 values of the objects in the bucket are the same as those of the local files. NOTE: If the size of the file or folder to be uploaded is too large, using this parameter will degrade the overall performance due to MD5 calculation. After the MD5 value verification is successful, the parameter value is set to the object metadata x-obs-md5chksum, which is used for later MD5 verification during download or copy.
p	Optional (additional parameter)	Indicates the maximum number of concurrent multipart upload tasks when uploading a file. The default value is the value of defaultParallels in the configuration file.
threshold	Optional (additional parameter)	Indicates the threshold for enabling multipart upload, in bytes. The default value is the value of defaultBigfileThreshold in the configuration file. NOTE: If the size of the file or folder to be uploaded is smaller than the threshold, upload it directly. Otherwise, a multipart upload is required. If you upload a file or folder directly, no part record is generated, and resumable transmission is not supported. This value can contain a capacity unit. For example, 1 MB indicates 1048576 bytes.
acl	Optional (additional parameter)	Access control policies that can be specified when uploading files. Possible values are: private public-read public-read-write bucket-owner-full-control NOTE: The preceding four values indicate private read and write, public read, public read and write, and bucket owner full control.
sc	Optional (additional parameter)	Indicates the storage classes of objects that can be specified when uploading files. Possible values are: standard: OBS Standard, which features low access latency and high throughput, and is applicable to storing frequently accessed data (multiple accesses per month) or data that is smaller than 1 MB warm: It is applicable to storing infrequently accessed (less than 12 times a year) data that requires quick response. cold: It is secure, durable, and inexpensive, and applicable to archiving rarely-accessed (once a year) data.
meta	Optional (additional parameter)	Indicates the customized metadata that can be specified when uploading files. The format is key1:value1#key2:value2#key3:value3. NOTE: The preceding value indicates that the object contains three groups of custom metadata after the upload: key1:value1, key2:value2, and key3:value3.
ps	Optional (additional parameter)	Indicates the size of each part in a multipart upload task, in bytes. The value ranges from 100 KB to 5 GB. The default value is the value of defaultPartSize in the configuration file. NOTE: This value can contain a capacity unit. For example, 1 MB indicates 1048576 bytes. The parameter can be set to auto. In this case, obsutil automatically sets the part size for each multipart task based on the source file size.
cpd	Optional (additional parameter)	Indicates the folder where the part records reside. The default value is .obsutil_checkpoint, the subfolder in the home directory of the user who executes obsutil commands. NOTE: A part record is generated during a multipart upload and saved to the upload subfolder. After the upload succeeds, its part record is deleted automatically. If the upload fails or is suspended, the system attempts to resume the task according to its part record when you perform the upload the next time.
r	Mandatory for uploading a folder (additional parameter) Optional for uploading multiple files/folders	Indicates files and subfolders within the folder when uploading a folder recursively.
f	Optional for uploading a folder or multiple files/folders (additional parameter)	Runs in force mode.
j	Optional for uploading a folder or multiple files/folders (additional parameter)	Indicates the maximum number of concurrent tasks for uploading a folder. The default value is the value of defaultJobs in the configuration file. NOTE: The value is ensured to be greater than or equal to 1.
msm	Mandatory for uploading multiple files/folders (additional parameter)	Enables the mode for uploading multiple files/folders. Possible values are 1 and 2. NOTE: If msm is set to 1, the source URL indicates a list of file/folder names separated by commas. If msm is set to 2, the source URL indicates a file containing a list of file/folder names. If the file or folder name already contains commas (,), do not set msm to 1. If parameter r is not set, the folders in the list will not be uploaded.
exclude	Optional for uploading a folder or multiple files/folders (additional parameter)	Indicates the file matching patterns that are excluded, for example: .txt. NOTE: The asterisk () represents any group of characters, and the question mark (?) represents any single character. For instance, *abc.txt indicates any file whose name starts with abc and ends with .txt*. You can use \ to represent * and \? to represent ?. If the name of the file to be uploaded matches the value of this parameter, the file is skipped. NOTICE: You are advised to use quotation marks for the matching pattern to prevent special characters from being escaped by the OS and leading to unexpected results. Use single quotation marks for Linux or macOS and quotation marks for Windows. The matching pattern applies to the absolute file path (including the file name and file directory). The matching pattern takes effect only for files in the folder. Multiple exclude parameters can be specified, for example, *-exclude=.xxx -exclude=.xxx*.
include	Optional for uploading a folder or multiple files/folders (additional parameter)	Indicates the file matching patterns that are included, for example: .jpg. NOTE: The asterisk () represents any group of characters, and the question mark (?) represents any single character. You can use \* to represent * and \? to represent ?. Only after identifying that the name of the file to be uploaded does not match the value of exclude, the system checks whether the file name matches the value of this parameter. If yes, the file is uploaded. If not, the file is skipped. NOTICE: You are advised to use quotation marks for the matching pattern to prevent special characters from being escaped by the OS and leading to unexpected results. Use single quotation marks for Linux or macOS and quotation marks for Windows. The matching pattern applies to the absolute file path (including the file name and file directory). The matching pattern takes effect only for files in the folder. Multiple include parameters can be specified, for example, *-include=.xxx -include=.xxx*.
at	Optional for uploading a folder or multiple files/folders (additional parameter)	Indicates that only the files whose latest access time is within the value of timeRange are uploaded. NOTE: This parameter must be used together with timeRange.
disableDirObject	Optional for uploading multiple folders (additional parameter)	Indicates the folders themselves are not uploaded as an object. Configuring this parameter can avoid uploading empty folders to a bucket. If a folder contains files, the files will be uploaded and the original path format is retained.
timeRange	Optional for uploading a folder or multiple files/folders (additional parameter)	Indicates the time range matching pattern when uploading files. Only files whose latest modification time is within the configured time range are uploaded. This pattern has a lower priority than the file matching patterns (exclude/include). That is, the time range matching pattern is executed after the configured file matching patterns. NOTE: The matching time range is represented in time1-time2, where time1 must be earlier than or the same as time2. The time format is yyyyMMddHHmmss. Automatic formatting is supported. For example, yyyyMMdd is equivalent to yyyyMMdd000000, and yyyyMM is equivalent to yyyyMM01000000. If this parameter is set to -time2, all files whose latest modification time is earlier than time2* are matched. If it is set to time1-, all files whose latest modification time is later than time1* are matched. NOTICE: Time in the matching pattern is the UTC time.
mf	Optional (additional parameter)	Indicates that the name matching pattern (include or exclude) and the time matching pattern (timeRange) also take effect on folders.
o	Optional (additional parameter)	Indicates the folder where operation result lists reside. After the command is executed, result lists (possibly including success, failure, and warning files) are generated in the folder. The default value is .obsutil_output, the subfolder in the home directory of the user who executes obsutil commands. NOTE: The naming rule for result lists is as follows: cp_{succeed \| failed \| warning}_report_time_TaskId.txt By default, the maximum size of a single result list is 30 MB and the maximum number of result lists that can be retained is 1024. You can set the maximum size and number by configuring recordMaxLogSize and recordBackups in the configuration file. If there are multiple folders and files and you need to confirm the detailed error information about a failed task, refer to the failure list cp_failed_report_time_TaskId.txt in the result list folder and the log files in the log path.
config	Optional (additional parameter)	User-defined configuration file for executing a command. For details about parameters that can be configured, see Parameter Description.
