You are helping the user set up or validate their Backblaze B2 CLI configuration.

Process

1. Check if B2 CLI is installed

   • Run b2 version to check installation
   • If not installed, install using: pip3 install b2 --upgrade --user or sudo apt install backblaze-b2

2. Check existing authorization

   • Run b2 get-account-info to see if already authorized
   • Check ~/.b2_account_info if it exists

3. Validate configuration

   • If authorized, test by listing buckets: b2 list-buckets
   • Verify account ID and key are working

4. Configure if needed

   • If not configured or user wants to update:
     • Ask user for Application Key ID and Application Key
     • Run b2 authorize-account <keyID> <applicationKey>
     • Alternatively, use b2 clear-account first if re-authorizing

5. Additional setup

   • Show available buckets: b2 list-buckets
   • Suggest setting up lifecycle rules if doing backups
   • Recommend testing upload/download with a small file

Output

Provide a summary showing:

• B2 CLI version
• Authorization status
• Account ID (if authorized)
• List of buckets (if any)
• Any recommendations for optimization
