Hi,

I'm developing RBD images' backup system. In my case, a backup data
must be stored at least two weeks. To meet this requirement, I'd like
to take backups as follows:

1. Take a full backup by rbd export first.
2. Take a differencial backups everyday.
3. Merge the full backup and the oldest (taken two weeks ago) diff.

As a result of evaluation, I confirmed there is no problem in step 1
and 2. However,
I found that step 3 couldn't be accomplished by `rbd merge-diff <full
backup> <diff>`
because `rbd merge-diff` only accepts a diff as a first parameter. Is
there any way
to merge a full backup and a diff?

Thanks,
Satoru
