VXA-2 tape really full ?
I am backing up several PCs using Backup Exec for Workstations
(version 4.61) to an Exabyte VXA-2 tape. I just started getting the message that the tape is full and it wants me to insert another tape. In theory, this is an 80 GB tape drive and I am using the VXA-2 80GB tape. This problem started happening using hardware compression and continues to happen using software compression. Backup Exec says that the tape is full at 1,683,781 files with 102,255,765,292 bytes with 1.89 : 1 software compression. I am totally surprised that I cannot write at least 150 Gb to the tape. Is the 64K block size on the tape killing me ? I did erase the tape using Exabyte's vxatool first. Is there some method of telling me exactly how much of the tape that Backup Exec is using ? Thanks, Lynn McGuire |

No. To expand on this, the tape drive does the compression, not the backup software, and with all the backup systems I've seen there's no way for the drive to report back how much actual compressed data is stored.
