I was wondering if someone could tell me what the average compression
factor is for the compress command? We are compressing some of the
filesystems in our nightly backups which makes it difficult to compute
how much data is actually being written to tape. If I knew the average
compression factor then I could make better estimates.
The Sun man page says 50-60% for English text or source-code. What
about for an entire filesystem? What about for an oracle database?
What about other things like say binaries?
Does anyone know?
