[求教] 关于savevg的block设置，是否能增加备份的速度

titan_S

有一个800G的vg要备份到LTO1，换卷没问题，但是上次用了8小时。问一下savevg的block设置，是否能增加备份的速度？多谢了

-b Blocks  

Specifies the number of 512-byte blocks to write in a single output operation. If this parameter is not specified, the backup command uses a default value appropriate for the physical device selected. Larger values result in larger physical transfers to tape devices. The value specified must be a multiple of the physical block size of the device being used.
