Zero-config daily backups of Claude session data, skills, and configs to cloud storage. Works for both Cowork and Claude Code — just run /backup-now and it auto-detects your environment, generates a unique instance ID, and backs up everything. Each user gets a collision-safe namespace so multiple users never overwrite each other's backups. Includes /backup-setup for customizing schedule, folders, and retention policy, and /backup-status to check when the last backup ran. Supports Google Drive out of the box with a cloud-storage-agnostic connector system.
