You start backup at 22:00 and it fails - when? Immediately at 22:00? If you'll try to start at 23:00 will it fail? Or at 21:50 will it fail at 22:00?<BR />General question is do we tied to 22:00?<BR />From the hardware point of view I would check if server's bios and SCSI card's bios are the latest and DLT drive firmware is a latest (use HP LTT, <A href="http://h18006.www1.hp.com/products/storageworks/ltt/index.html" target="_blank">http://h18006.www1.hp.com/products/storageworks/ltt/index.html</A> )<BR />Eugeny Fri, 07 Mar 2003 09:27:50 GMT https://community.hpe.com/t5/netservers/strange-backup-problem-hp-netserver-tc4100-vs80dlt/m-p/2921885#M4442 Eugeny Brychkov 2003-03-07T09:27:50Z
