Hi,
I've redirected my reply to <backuppc-devel> (and changed the subject) because
your issue does raise a question regarding the design of the web interface.
And sorry if I've misquoted you :).

Prior to the notion of multi-level incremental backups, there were two
choices for manual backups: do a full backup or do an incremental backup.
Is the matter still so simple with multi-level incrementals? In the example
above, if the last run backup was level 2, I could meaningfully request
- a full backup
- a level 1 incremental
- another level 2 incremental or
- a level 3 incremental
to be run, and at least three of these options seem to make sense:
- I need a full backup done now. Period.
This can already be done.
- The previous level 2 incremental was, for some reason, not what I wanted.
Redo it now.
- Prepone the normal level 3 incremental to right now.
Of course, the administrator might also have a good reason to say, "do an
incremental relative to the last full backup" (which would be level 1).
I'm not quite sure how it works right now, because I don't use multi-level
incremental backups (yet), but I'd guess the "incremental backup" button
either always does level 1 or whatever would be due next according to the
configuration. Of these, the latter option seems to be preferrable.
Would it make sense to add the option to "Start level X incr backup" where X
would be specified in a text input field? Strictly, that one option would
suffice (level 0 is a full backup), but retaining "Start full backup" and
"Start whatever incr backup is due" for convenience would probably be a good
choice.
What does "run whatever is due" do if a full backup is due next? What effect
do manual incremental backups have on the automatic schedule?
Regards,
Holger
