corrupt copy

基本解释

If you don’t have a backup copy of the corrupt document readily available, make a copy of the corrupted file right away and store it on removable media.
如果你沒有損壞文档的可讀備份版本，需馬上複制一份損壞文档的備份到可移動介質上。
Note: Remember you must never apply the delta file to a copy of image A that has been changed, booted from in private image mode, or even mapped on an Ardence server. Doing so will corrupt the image.
注意如果生成增量文件後又映射過磁磐A或以獨享模式啓動過磁磐A，就不能再使用這個增量文件了，那樣做會損壞磁磐A。
