Quick Start Guide

Prepare B2 cli

$ b2 account authorize 4ab123456789 001aabbccddeeff123456789012345678901234567

Get credentials from B2 website


Local users might be able to access your process list and read command arguments. To avoid exposing credentials, you can provide application key ID and application key using environment variables B2_APPLICATION_KEY_ID and B2_APPLICATION_KEY respectively. Those will be picked up automatically, so after defining those you’ll just need to run b2 account authorize with no extra parameters.

$ export B2_APPLICATION_KEY_ID="$(<file-with-key-id.txt)"
$ export B2_APPLICATION_KEY="$(<file-with-key.txt)"
$ b2 account authorize

$ b2 sync "/home/user1/b2_example" "b2://bucket1/example-mybucket-b2"


Sync is the preferred way of getting data into and out of B2 cloud, because it can achieve highest performance due to parallelization of scanning and data transfer operations.
