Sorry for the late reply.Thanks your Advise was very helpful

Please change according to the below link http://urenjoy.blogspot.com/2008/12/cannot-open-backup-device-sql-server.html No need to give read, write permissions to give for users. Thanks Harish

I still had the problem with both the Admin and SQL account having read/write access to the share and Everyone set to Full Control. I then read "Only a member of the Farm Administrators group can take a backup using Central Administration. Also you need to have Full Control on the shared given to the SQL Server service's account, SharePoint 2010 Timer Service and Central Administration's application pool identity account." [http://www.mssharepointtips.com/tip.asp?id=1040&page=4]. It now works. Not tested it with Everyone having only Change rights yet.
