Gnucash compresses its files using gzip. Gzip uses LZ77 followed by 
Huffmann coding (DEFLATE). ZIP also uses DEFLATE, but its file format is 
different.

Once a file has been compressed by gzip, compressing it again using 
another compression tool is unlikely to make the file smaller by any 
significant amount.

Gnucash doesn't have built-in encryption. If you're using volume-level 
encryption, then it will compress first, then encrypt. Any half-way good 
encryption should make the file pretty much impossible to compress if 
you encrypt first.
