Raspberry pi のSDカードをMac OS Xでバックアップしてレストアして。

More than 5 years have passed since last update.

バックアップ

データを丸っと取ってくる。

sudo dd bs=1m if=/dev/disk{NUM} of=~/Desktop/backup.img

レストア

SDカードを差し込んだら、FATにフォーマットしてそのボリュームを一度コマンドでアンマウントします。
フォーマットはディスクユーティリティーなどを使用してください。

sudo umount -fv /Volumes/{UNTITLED}

次にデータを流し込みます。

sudo dd bs=1m if=~/Desktop/backup.img of=/dev/disk{NUM}
