asked on

size of db reduced after transfer

I got a Intel box and a Alpha box.
I transfered a database from Intel to Alpha and the size of the database on the Intel is and was 440 mb on Alpha it's only 90 mb.
Anyone knows why?

How did you transfer the database? Using transfer manager. You cannot transfer databases from Alpha to Intel or viceversa, you will have to dump the database and restore. Create a device the same size on Intel , make sure you have the same sort order and case and then restore.

Sorry my mistake is the other way around, disregard what I said.  Reject the answer
There ara a few reasons I can think of:
1. Your database is very fragmented and when you transfer it your database gets defragmented - you can check this by transfering your database to the same computer and check the results.
2. Both transaction log and database are on the same device - it is possible then that your transaction log is very big and after the transfer it is empty.
3. You didnot select to transfer every object from the destination database.

Inserting and deleting a larger number of pages has two consequences (keeping in mind that the transaction log is empty before a transfer):
1) There is a large number of data pages, that are near-empty
2) The ideal structure of the indexes is achieved on a newly-formed index tree, but cannot be maintained on a frequently updated table (update/insert/delete) unless a rebuild of indexes is done before a transfer. Therefore, many index pages are also not filled-up ideally, as is the case of data-pages.
