rsync でデータ移行したときのメモ（macOS）

古いmacから新しいmacへデータを移行をrsyncで行ったときのメモです。

rsync

移行先で実行

rsync -auvzE --progress 移行元のIP:~/Desktop ~/Desktop
  • a archive mode; same as -rlptgoD (no -H)
  • u skip files that are newer on the receiver
  • v increase verbosity
  • z compress file data during the transfer
  • E copy extended attributes
  • --progress show progress during transfer

macOS の場合は、E オプションをつけて拡張属性もコピーされるようにしておく。

移行元へ ssh で接続できるようにシステム環境設定の「共有」で「リモートログイン」を有効にしておく。 移行が終わったら忘れずに無効にする。

rsync でエラーが出る場合

Write failed: Broken pipe でエラーを吐いて、ClientAliveInterval などを調整しても効果がないときは Homebrew から最新の rsync を入れてしまう

brew install rsync
