Usage notes

  • One of SOURCE_PATH or DESTINATION_PATH must be a local directory, while the other should be a directory in the Snowflake stage. The stage path must start with “@”. For example:

    • snow stage copy @my_stage dir/ - copies files from my_stage stage to the local dir directory.

    • snow stage copy dir/ @my_stage - copies files from the local dir directory to my_stage.

  • You can specify multiple files matching a regular expression by using a glob pattern for the source_path argument. You must enclose the glob pattern in single or double quotes.

Examples

  • To copy files from the local machine to a stage, use a command similar to the following:

    snow stage copy local_example_app @example_app_stage/app
    Copy
    put file:///.../local_example_app/* @example_app_stage/app4 auto_compress=false parallel=4 overwrite=False
+--------------------------------------------------------------------------------------
| source           | target           | source_size | target_size | source_compression...
|------------------+------------------+-------------+-------------+--------------------
| environment.yml  | environment.yml  | 62          | 0           | NONE             ...
| snowflake.yml    | snowflake.yml    | 252         | 0           | NONE             ...
| streamlit_app.py | streamlit_app.py | 109         | 0           | NONE             ...
+--------------------------------------------------------------------------------------

  • To download files from a stage to a local directory, use a command similar to the following:

    mkdir local_app_backup
snow stage copy @example_app_stage/app local_app_backup
    Copy
    get @example_app_stage/app file:///.../local_app_backup/ parallel=4
+------------------------------------------------+
| file             | size | status     | message |
|------------------+------+------------+---------|
| environment.yml  | 62   | DOWNLOADED |         |
| snowflake.yml    | 252  | DOWNLOADED |         |
| streamlit_app.py | 109  | DOWNLOADED |         |
+------------------------------------------------+

  • The following example copies all .txt files in a directory to a stage.

    snow stage copy "testdir/*.txt" @TEST_STAGE_3
    Copy
    put file:///.../testdir/*.txt @TEST_STAGE_3 auto_compress=false parallel=4 overwrite=False
