Command Syntax

The sync command is used to sync object upload, download, and copy. The difference between sync and cp is that sync first compares the CRC64 value of an object with the same name that already exists, and if the value is the same, the object will not be transferred.

./coscli sync <source_path> <destination_path> [flag]

Note：

• For more information on bucketAlias, see Download and Installation Configuration.
• For more general options for this command (such as switching buckets or user accounts), see General Options.

sync includes the following optional flags:

Note：

• sync automatically uses concurrent upload/download for large objects.
• If an object is larger than --part-size, COSCLI will split the object into multiple parts according to --part-size and use --thread-num threads to concurrently upload/download the object.
• Each thread maintains a URL. For each URL, you can use the --rate-limiting parameter to limit the speed of a single URL. When concurrent upload/download is enabled, the total rate is --thread-num * --rate-limiting.
• If an object is uploaded/downloaded in parts, checkpoint restart will be enabled by default.
• --include and --exclude support standard regular expression syntax, so you can use them to filter files that meet specific criteria.
• When using zsh, you may need to add double quotes at both ends of the pattern string.

./coscli sync ~/test/ cos://bucket1/example/ -r --include ".*.mp4"
