We have one BE-server with four Sony AIT Tapestations to be able to backup four servers at the same time. When backing up 32-bit servers simultanously there are no problem. Also everything goes smoothly when a 64-bit server are backed up alone.
However, when a 64-bit server and another server, 32-bit or 64-bit, are backed up at the same time strange things happen. Then the 64-bit servers only runs about 30 MB/sec instead of normally over 1 GB/sec???
Anyone has a clue?
