一种办法是把其他服务器上的大存储NFS挂过来。
或者就是parallel compression ,不生成中间文件,直接打包压缩。
下面摘了段官方的介绍
Parallel compression (‘--compress-threads‘) can be used together with parallel file copying (‘--parallel‘). For example, ‘--parallel=4 --compress --compress-threads=2‘ will create 4 IO threads that will read the data and pipe it to 2 compression threads.
New streaming format to work with parallel compression.
The xbstream format is now supported along with the tar format. The new xbstream format works with parallel compression to (without caching) stream several compressed files at once. |
