DLT7000 Backup fails to use the full 35G capacity
Posted on 2005-03-20
I am using a IBM/Quantum DLT7000 to do a FULL back up of 28 Gigabytes of MP3 data on a DLTIV 40/70/80 tape. Using BackUp Exec 8.6 (also tried version 10) the process goes over the 28G's, reaches about 30G, and asks for a second tape. For what I don't know, as stated, the original data is 28G. However, if I use Acronis True Image Server, it mounts the DLT drive and according to the softeware, compacts the whole HDD/28G on down to about 16G. Full backup on one tape, no problem. I would prefer to use BU Exec because I can choose folders instead of imaging complete drives. Why the heck would 28G not fit on a 35G tape? Are my BU Exec settings wrong? I am stumped.
