Yes, using one forest but planning on adding 2 more and redistributing the
content.

Subject: Re: [MarkLogic Dev General] Backup question

A non-incremental backup will be almost exactly the same size as the original
forest(s). For the most part forests aren't compressible, and the backup doesn't
try. To see how this works, take a look at the filesystem layout of the backup
and the original forest(s).

I'm not sure where concurrency comes into this: you say you're only using one
forest?
