In this shell snippet, the line continuations won’t work if someone copy/pastes: in POSIX shells the \ must be the last character on the line (no trailing spaces, and you can’t put an inline comment after it). Consider moving the comments onto their own lines (or above each option) and leaving the backslash as the final character.

	-O compression=lz4 \ # or zstd, off, gzip
	-O atime=off \ # performance/drive health
	tank raidz1 \ # pool name and zfs config

Same issue with line continuations here: there’s a backslash followed by an inline comment/spaces, which breaks the intended multiline zpool create command if pasted into a shell. Move comments to separate lines and keep \ as the last character on each continued line.

This section is using zpool create/zpool set for dataset operations, but datasets are managed with zfs (e.g., zfs create tank/backups and zfs set compression=... tank/backups). As written, these commands will fail or do the wrong thing when followed literally.

Suggested change

	sudo zpool create tank/backups
	# optionally, change metadata:
	sudo zpool set compression=zstd tank/backups
	sudo zfs create tank/backups
	# optionally, change metadata:
	sudo zfs set compression=zstd tank/backups
