Bug Description

[In:Streaming and Compressing Backups]

The page referenced above describes the streaming features of innobackupex in detail, but doesn't state that streaming is not supported in combination with incremental backups.

If both --stream and --incremental-lsn are passed to innobackupex, the incremental parameters are ignored and a full backup is created. This appears to be well-known by certain members of the community (see the discussion here http://groups.google.com/group/percona-discussion/browse_thread/thread/ab665133c53c49cd which is also quoted below)

"But the real problem is that streaming + incremental backups are
currently not supported, because streaming is done exclusively in
innobackupex, while incremental backups must be performed by the
xtrabackup binary to scan the data files and calculate deltas. This will
be fixed in XtraBackup 2.0. "

This just cost me a couple of hours of banging my head against LSNs and test backups. It really should be documented both on the "Streaming and Compressing Backups" page (linked above) and on the option reference for innobackupex (here: http://www.percona.com/doc/percona-xtrabackup/innobackupex/innobackupex_option_reference.html)
