Redis

type: redis — produces an RDB snapshot. Two modes:

Live dump (default) — runs redis-cli --rdb <out> against a running server. Redis triggers a background save and streams the resulting RDB to snapr.
File copy — when path is set, snapr simply copies the existing RDB file from disk. No server connection is made.

Prerequisites

For mode 1: redis-cli must be installed on the snapr host and available in PATH (Debian/Ubuntu: redis-tools).
For mode 2: snapr just needs read access to the RDB file — no client tools required.
The configured user (when ACLs are enabled) needs at least the ~* +@read +bgsave +replconf +psync +ping permissions, or simply the predefined ~* +@all role for a dedicated backup user.

Field	Type	Required	Notes
`type`	`redis`	yes
`path`	string	no	absolute path to an RDB file. When set, snapr copies it instead of dumping.
`host`	string	yes*	required unless `socket` or `path` is set. Defaults to `127.0.0.1`.
`port`	int	no	default `6379`
`socket`	string	no	UNIX socket path
`username`	string	no	Redis 6+ ACL username (passed as `--user`)
`password`	string	no	passed via `REDISCLI_AUTH` env var, never on cmdline. Use `env:`.

Live dump triggers a save on the server side. On large datasets the snapshot fork can briefly impact memory and latency.
The output filename is always dump.rdb inside the job's working directory.
