partimage ( partation 備份)

最後更新: 2016-10-12

 

介紹

 

partimage 可以說是 linux 上的 ghost 來. 它可以用來備份 partation to image

厲害的是它無需內核的支援, 就可以讀取以下檔案系統

Ext2/3, Reiser3, FAT16/32, HPFS, JFS, XFS,UFS, HFS, NTFS

而且它只會備份使用到的 block, 所以 backup 的速度很快

( 它什至會記得 block 在 partion 上的位置 )

在現時的版本並不支援 ext4, btrfs 等格式, 而且不能 restore 到較 IMG 細的 partition

與其他工具比較

# dd 是會 backup 在 partation 上仕何的東西都, 包括未用的空間,  所以要花很多時間.

# dar 需要 kernel 支援才能讀取要備份的檔案,

 

主要功能

partimage 主要有大動作有 save, restore, imginfo, restmbr,

以下一一介紹

 

Version
