I assume you mean using BackupPC_zcat.

If you already have a working backuppc instance, look at the page for
any host.  The bottom table give you the compression ratios. I have
some hosts that routinely have 80% compression (database
backups). Others have 0-2% (data directories with most of the data
already compressed).
