 Uses `pkgacct --nocompress --skiphomedir` for account backups, gzips SQL files individually, and transfers everything (including homedirs) to remote destinations with incremental snapshots. Supports three remote types: **SSH** (rsync with hardlink-based `--link-dest`), **Amazon S3** / S3-compatible (via rclone), and **Google Drive** (via rclone). Supports multiple remote destinations with independent schedules and retention policies.
