Documentation: Clarify Compress and Uncompress Options in Cbbackup/CbabbackupWrapper, CbRestoreWrapper

+Background: +

There seems to be much confusion over whether compression is enabled in the legacy cbbackup and cbrestore utilities: the purpose of this Doc Bug is to get documentation consistency across all CB versions.

According to MB-10917, cbbackup compression capability is delayed until Spock. However, the documentation for cbbackup shows a compress and uncompress option now: http://docs.couchbase.com/admin/admin/CLI/cbbackup_tool.html.

Cbbackupwrapper in 4.5.1 has an "uncompress" flag in its option list if one executes "cbbackupwrapper help" ; this option is not found in the option list of cbbackupwrapper for 3.1.X. the "uncompress" option is listed in the cbbackupwrapper documentation although, again, it is not documented very clearly. See http://developer.couchbase.com/documentation/server/current/cli/cbbackup-wrapper.html.

So there is much confusion over whether compression has been introduced into the existing cbbackup/cbrestore utilities and their wrappers, and additional confusion of how the "uncompress" flag actually works in the various utilities.

Can we get this clarified and retrofitted into the docs?
