data missing in the full backup

i have a 2005 db with full recovery mode. daily full backups, diff backups and log backups are done through sqlagent. i wanted to make a copy of it on another instance using the restore method with the latest full backup. after i created the new db, i noticed that a few tables were missing and columns were missing from existing tables also. futhermore, the recrods in these tables were not up-to-date either. i did fresh a full backup and tried again and the problem persisted. i aslo tried to restore on the same sql server instance under a different db name and that reproduced the problem.

the database schema was changed a few weeks ago and it seems that i am only seeing a snapshot of the database before the schema change. dbcc checkdb returns no error. the size of the backup file looks reasonable and i seen an increase in size since the schema change which is expected. there is no active transactions in the db and if i generate a create script, it contains proper t-sql that matches the current schema.

what am i missing there? what could i be doing wrong? i am lost here and any help or advice will be greatly appreciated!

i found the problem. the backup script didn't specify INIT and SKIP so an older set was used by the restore operation.
