Compression in newest Version?

[Canoe]

Dave,

I have a 160 GB MacBook, but the drive is not even close to full.

I am looking at a hot swappable firewire portable backup drive (100 GB).

I cannot locate a compression feature in the new SuperDuper! version for .dmg

1. Is compression not available?

2. If not, what is the size of .dmg file compared to the original. (e.g. 80%, 110%, etc.)

Thanks,

Hal

Compression is generally impractical in this situation: you need 2x the space to compress... but you don't need it if your drive isn't close to full!
