erase-on-allocate
分配时擦洗法
A technique that applies an erasure pattern whenever a new area is allocated for a file's extent. The new area is erased with the erasure pattern so that subse- quent attempts to read the area can only yield the erasure pattern and not some valuable remaining data. This technique is used to discourage disk scavenging.
每当新的存储区域分配给某个文件时,所采用的一种数据保护技术,即用擦洗模式对新的 存储区域进行清洗。这样,其后对该区域的读操作只能得到擦洗模式,而得不到有用的保存 数据。这种技术能保证磁盘不被他人浏览。 |
