In regard to: [Networker] Does removing a save set affect the index?,...:

What happens if you remove a save set that is still browsable? Will this update the index?

It should.  It's possible that you'll need to force nsrim to run, but
I kind of doubt it.

You can very easily test this.

If not then what happens, for example,
if you then rerun another incremental on the client?

Well, that depends.  If you removed a saveset that was the most recent
incremental, then the next incremental you do should back up all files
that have changed since the backup (of any level) prior to the incremental
you removed.  In other words, I believe that it should be the same as if
the incremental that you removed had not be done.

If the saveset you remove is incremental but *not* the most recent, then
nothing special happens -- the incremental you do should backup up
everything that's changed since your most recent backup.

If the saveset you remove is *not* incremental, then the rules might be
slightly different, possibly depending on multiple factors.

If it captures everything since the last incremental, but you don't have that save set because you deleted it then what use would the latest incremental be if you had to rebuild something?

It should back up everything that's changed since the last backup (of
any level, not just incremental) *it knows about*.  If you've deleted the
most recent incremental and then do a new incremental, it should back up
everything that's changed since the most recent backup for that volume
that you still have (browseable).

Again, this is something you could test very easily.  If you do, report
back to the list.

What should you do in this case? Run a full or some kind of level backup to make it go back to before the incremental that you removed?
Seems like overkill.

Or, just get on the client and run a manual incremental and specify a date value of just before the date of the incremental that you removed?

If you're removing the most recent incremental, I honestly don't think
either of these things are necessary.  Just do a normal incremental.
If you're removing something other than the most recent incremental, then
all bets are off.
