Problem with using method 'Sql2005CreateBackup'

[masmart]

Hello guys.
I tried to get backup of me database using method 'Sql2005CreateBackup' but
when I trying to call it, this error occurs:
DiscountASP.net.UserErrorException: Method 'Sql2005CreateBackup' can only be
called once every 21600 seconds.
how can I resolve this problem?
Thanx for any help.

It's an intended limitation implemented on the web service to prevent needless and excessive load. The only way to resolve it is to call it less often, once every 6 hours at most.
