说明
rusnapshot is a simple and handy BTRFS snapshotting tool written in Rust. It provides snapshot creation, management, restoration, and automatic cleanup for BTRFS filesystems, using SQLite to track snapshots. Configuration is done via TOML files specifying snapshot source and destination paths, prefixes, and kinds. Snapshots can also be fully specified via command-line flags using --from and --to.
