usbはfat32にフォーマットしたものを使う
新品は通常fat32にフォーマットされている。
# apt-get install extlinux
自動でマウントされたusbをアンマウントする
# lsblk
上記で表示されるマウントポイントをumountする
# umount /media/ユーザー名/UUID名
usbを起動できるようにフォーマットする
# /usr/local/sbin/rear/usr/sbin/rear format -- --efi /dev/sdb
一旦、usbを抜き差しする
フォーマットが終了したら一旦USBを抜き差しする REAR-000ラベルを確認する
自動でマウントされたusbをアンマウントする
# lsblk
上記で表示されるマウントポイントをumountする
# umount /media/ユーザー名/UUID名
設定ファイルを作る
# mkdir /usr/local/sbin/rear/etc/rear/usb-local/ # vi /usr/local/sbin/rear/etc/rear/usb-local/local.conf
### write the rescue initramfs to USB and update the USB bootloader
OUTPUT=USB
OUTPUT_URL = usb:///dev/disk/by-label/REAR-000
### create a backup using the internal NETFS method, using ‘tar’
BACKUP=NETFS
### write both rescue image and backup to the device labeled REAR-000
BACKUP_URL=usb:///dev/disk/by-label/REAR-000
レスキューシステムを作る
# /usr/local/sbin/rear/usr/sbin/rear -c /usr/local/sbin/rear/etc/rear/usb-local/ -v mkrescure
BIOSを変更して起動する
BIOSを変更する 起動はEFI:USB名のついた項目を選択して起動する
これで成功すればmkbackupで正式なバックアップをとる
# /usr/local/sbin/rear/usr/sbin/rear -c /usr/local/sbin/rear/etc/rear/usb-local/ -v mkbackup
