Time Machine のバックアップ対象が延々と増え続けて焦った
タイトルの通り、Time Machine のバックアップ対象が延々と増え続けてバックアップが終わらなくなりました。
直前のバックアップでは 10 分程度で正常に完了しており、そのあとは Mac を放置してロッキーをみていたので、変更はほとんどないはずです。にもかかわらずバックアップ対象がどんどん増え続け、最初は数十 MB だったのが 10 GB を超えても終わらず、やむなくキャンセル。(このあと手動で再開させたら 20 GB を超えても終わらなかった)
明らかにおかしいので、いろいろ試してみました。
- Mac の再起動
- Disk Utility で TimeMachine ディスクをチェック
- TimeMachine にある .inProgress ファイルを削除
- Sophos Anti-Virus の Live Protection および On-access Scanning を停止
- Time Machine から前回のバックアップを削除
どうやらバックアップ削除が正着だったようで、このあと Time Machine を走らせると正常に終了しました。(もしかしたら .inProgress の削除も必要なことだったのかも)
