Eh, it's a bit more finicky than that.
ePub is based on zip, so you wouldn't get too much space savings from that -- compressing an already-compressed file is kinda pointless (in fact, it's well possible for it to
increase the size).
Other formats vary - PDFs seem to vary depending on how well it was already compressed, plain text and HTML compresses fairly well, not sure about the Amazon formats.
Also, the more files you compress, the more that the compression software can find abcabcabc's to crunch down into abc[3].
In any case, doing an occasional manual rar backup of my library (as opposed to just loose folders), even with a recovery record*, shaved off enough space for me to bother doing it. Though I do set it up to run when I'm about to go to sleep.
* I'd use 7z, but it lacks a recovery record.
