[操作疑難] 我 luks - encryption 新手, 有人可以指教下嗎? thx

最近有部 notebook,

安 win7, win8, win10 都有問題。
(core 2 duo, 8G ram)


一氣之下安左 ubuntu 16.04.

發覺改進左好多,
估唔到 ubuntu/linux market share 咁細,
但係d program 個quality 唔錯.



ubuntu installer 如今唔洗 alternative installer,
正如 bit locker 一樣, 好common.

不過 ubuntu 還有得選   disk encrypt +/- home folder encryption. (後者唔敢選,
在windows 中過伏).


但係呢幾日試, so far OK,
但成日都聽過 ubuntu boot 唔番起。

未指教 120GB full luks encrypted + 用左 lvm (我根本唔知乜黎)的system,
點樣backup 最好呢?  ubuntu 16.04 64b desktop.

我指 ghost-ing, imaging o個d.

120GB 如果可以 split做  2GB s 咁就最好啦.

先謝~

usually, backup your own folder. how big is it ( i mean data)

如果要成隻SSD/HDD backup, Clonezilla 幫到你。
http://clonezilla.org/

剩係backup 某些 data 可用Cron job tar 起擺系第二都(NAS/Other linux/Windoz etc)。或用rsync 備份至第二部機。

    師兄,

"窮? 你死啦!"    係會成 120GB (encrypted data + encrypted empty space) 都clone o西, 因為佢係clone by sector if encrypted.

咁其實都OK,

但係 clone 左出黎的 120GB, encrypted disk image,
有無方法看下入邊d file?

thanks.

LVM = Logical Volume Manager, 有以下用途:
https://en.wikipedia.org/wiki/Logical_Volume_Manager_(Linux)

Common uses[edit]
LVM is commonly used for the following purposes:

-- Managing large hard disk farms by allowing disks to be added and replaced without downtime or service disruption, in combination with hot swapping.

-- On small systems (like a desktop at home), instead of having to estimate at installation time how big a partition might need to be in the future, LVM allows file systems to be easily resized later as needed.

-- Performing consistent backups by taking snapshots of the logical volumes.
Creating single logical volumes of multiple physical volumes or entire hard disks (somewhat similar to RAID 0, but more similar to JBOD), allowing for dynamic volume resizing.

--LVM can be considered as a thin software layer on top of the hard disks and partitions, which creates an abstraction of continuity and ease-of-use for managing hard drive replacement, re-partitioning, and backup.
