Hi,
If i do a mongodump and restore of a collection (one that has
indexes), after restore, i would ask mongo to rebuild the indexes
right? is this metadata that's stored in a system table?

By default mongodump produces a file called system.indexes.bson inside
each database's dump directory.
mongorestore loads that file last within the database. Loading that
file builds indexes in the new database. Only the metadata is in these
files, so loading it will create the indexes.
There was a bug http://jira.mongodb.org/browse/SERVER-2186 that now
has been fixed in case the db name was different between old and
new.

you're talking about a full db mongodump right?
i'm asking about a single collection mongodump
mongodump -d my_db -c my_col
would a single collection mongodump backup and (mongorestore) the
indexes for that collection?
