Ok, but how do I restore the statistics?  Using "update" statements?

Thanks in advance for your help.

to "backup" statistics you can run query on rdb$indices and rdb$index_segment tables. And save result to the file.

About table statistics - here is really fine concept that you do not need to recalculate anything. Table pages count and record size is taken in calc. In fb3 also record compression level.
