1Password Backup Sync

Syncs 1Password's backup files to multiple Macs. This applies to 1Password bought as standalone license, not membership.

Tested on:

• macOS Big Sur (Intel)
• macOS Monterey (Intel)
• macOS Ventura (Apple Silicon)

Getting Started (One Time Setup)

IMPORTANT: Repeat the following steps in each host.

• Ensure SSH keypair exists (ex: ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub). If missing, run create one:

ssh-keygen

• Copy public key (ex: ~/.ssh/id_rsa.pub) to each remote host's ~/.ssh/authorized_keys. If this file doesn't exist, create it.

• Ensure the current machine's .ssh/ directory and file have correct permission:

chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

• In the current machine's /etc/hosts:
  • Add all remote hosts
  • Add hostname to 127.0.0.1

127.0.0.1      localhost myshittycode # if current machine's hostname is "myshittycode"
192.168.1.100  donkeykong # remote host 1
192.168.1.200  supermario # remote host 2

• Enable the remote login and grant yourself the access to this service.

• Test SSH connection to remote host to ensure they work.

ssh user@donkeykong
ssh user@supermario

• Made a copy of inventory-sample.yml and rename it as inventory.yml.

• Modify inventory.yml to add all hosts.

• Test SSH connection with Ansible.

ANSIBLE_PYTHON_INTERPRETER=$(which python3) ansible all -i inventory.yml -m ping

Syncing the Latest Backup File to all Remote Hosts

To push the latest backup file from the current machine to all remote hosts, run Ansible playbook.

./1password-backup-sync.sh

• In each remote host:

  • Open 1Password.

  • Go to Preferences > Backup.

  • The synced backup file should appear in the list.

  • Select it and click Restore button.

• To run the playbook in the future, run 1pass in the terminal.
