Schedule Job : Backup Encryption hasnot finish completely.

Question

Dear Mr/Ms,
           SQL Server 2008 has backup encryption schedule job for 02 databases, but it has just backed up 01 database in several time.
Access is denied due to a password failure [SQLSTATE 42000] (Error 3279)  BACKUP DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013).  The step failed.
I have enough space for backup file.
Please help me solving this problem completely.
Thanks and best regards,

Have you tried with PASSWORD='Password123'
instead of mediapassword?
Passwords can be used for either media sets or backup sets:
Media set passwords protect all the data saved to that media. The media set password is set when the media header is written; it cannot be altered. If a password is defined for the media set, the password must be supplied to perform any append or restore
operation.
You will only be able to use the media for SQL Server backup and restore operations. Specifying a media set password prevents a Microsoft Windows NT® 4.0 or Windows® 2000 backup from being
able to share the media.
Backup set passwords protect only a particular backup set. Different backup set passwords can be used for each backup set on the media. A backup set password is set when the backup set is written to the media. If a password is defined for the backup set,
the password must be supplied to perform any restore of that backup set.
