TSM backup of MS Sql , Error no storage space

Hi everyone ,

I was trying to backup a MS SQL database , received error "No storage space - increase the storage space ".
I even tried to " set COMPRESSALWAYS=NO and COMPRESSIon=YES in the options file (DSM.OPT) " but it gave invalid parameters message .

How should I increase storage space ?
Please help me ..!!


Thanks in advance
