Backup DB on compressed folder

Hi I have a very strange case here.
Currently our db server is short of space and as a temp solution database is backed up to a compressed folder. OS is W2K advanced Edition and SQL is Enterprise version. Database is 62GB now. every time Db backup fails after backup running for 2hrs and hal
f. the error msg says that "18210 :
BackupMedium::ReportIoError: write failure on backup device 'd:\mssql\backup\DataDMP01.BAK'. Operating system error 33(The process cannot access the file because another process has locked a portion of the file.)."
we have tried another file name or rebooting the server, but none helps.
I doubt that compressed fold causes the problem or exceeds the file size limit, but can not find any clue on it.
Pls help.
thanks for reply.
George
Compressed drives are not supported for sql server databases and to the best
of my knowledge backups either. If you are low on disk space I would
suggest using a product such as SQL LiteSpeed.
