小弟我最近在試dd的指令備份系統
dd backup:
sudo dd if=/dev/sda | gzip > /media/louislin/My\ Passport\backup.img.gz
這一步是沒什麼太大的問題,都有備份至我的隨身硬碟中
那在還原時
dd restore:
sudo gzip -dc /media/louislin/My\ Passport/backup.img.gz | sudo dd /dev/sda
將dd備份好的壓縮檔解壓縮回去至系統
那我想問的是上面這個restore command 是該在哪裡執行呢
目前試過:
1.
如果是進了系統再下此command,restore完都會當機且重開機後也進不去系統,直接進到
emergency mode ,且tab那些都無法使用。
感覺就是直接在系統中restore會有問題。
如果要做restore的動作,有什麼前置流程要做的呢?方可保證restore完不會有問題?
麻煩各位解答了。非常感謝
