Recover data from yesterday

Hi,
I'm not a database manager,
I have to recover the old database instead of the actual.
I backed up the old one from a tape backup.
Do i have just to rename the existing one and copy the one
that i want in the same folder.
People told me that there was no change between these two
version except that someone erase a folder.
Thank...
If you are talking about SQL Database (instead of MDMArch'd Analysis
Services database) ,YOu may restore the SQL database using the restore
wizard, but
1. Restore as a DIFFERENT database name and
2. on the second tab, choose DIFFERENT PHYSICAL FILENAMES/Locations for
each file so you will not overwrite the good, current version of the
database...
