Move Files with the CLI
The Backblaze B2 Cloud Storage command-line interface (CLI) supports the
b2-copy-file-by-id command that you can use to copy a file from one bucket to another bucket.
The context for making this call in the CLI is as follows:
b2 copy-file-by-id <sourceFileID> <destinationBucketName> <b2FileName>
sourceFileID is the file ID of the file that you want to copy to the new bucket.
There are two options to find a file ID:
- Use the
list-file-namescommand in the Backblaze B2 CLI.
- In the Backblaze web UI, click the ‘i’ icon next to a file. The Fguid is the file ID for that file.
The following example shows you how to copy a file from one bucket to another bucket.
