Depending on the definition of offsite, you have a fundamental problem: either invest the time/effort compressing or take extra bandwidth, which is less costly? Hopefully a delta transfer makes sense in your situation and should save far more than compression would once the original copy is offsite.

unless you use tape (of that high capacity), it is advantageous to
restrict volume size to, say, 50GB. Then when you restore, search for
specific files will be faster. And it will help your backup volumes
transfers as well.
