Have you find a solution to fix it ?<BR /><BR />Please help me.<BR /><BR />Thanks Mon, 10 Sep 2007 14:57:47 GMT Briag 2007-09-10T14:57:47Z https://community.hpe.com/t5/hpe-storeever-tape-storage/dat72-compression/m-p/3965355#M19946 This subject has been raised by other people before, but I am still unclear as to the way forward.<BR /><BR />I am using an external SCSI C7438A Dat72 drive on Windows SBS 2003 using Backup Exec 10 SBE. When installing backup Exec, I chose to use their drivers and had not previously installed the HP drivers which came with the tape backup unit.<BR /><BR />Everything works fine, but selecting to use hardware compression appears to be no different than selecting no compression at all and I can get no more than about 33GB on the tape.<BR /><BR />I have loaded the latest LTT software, updated to the latest firmware, enabled hardware compression and the tests show that I am getting 2.2:1 compression.<BR /><BR />What I refuse to believe is that with a wide range of system files, Exchange files and general Word and other database files being backed up, that the actual compression on a real backup can be 1:1. There has to be something which although Backup Exec appears to allow me to use hardware compression, in fact it is not.<BR /><BR />Can anyone suggest a way forward or further tests I can carry out?<BR /><BR />Thanks.
