I've gotten almost 1 TB on a LTO2 tape. It was filled with daily incremental jobs which was mostly highly compressible log files. From what I've gathered the Volume Bytes are uncompressed bytes. Since the compression is done on the hardware, Bacula doesn't know the 'true' bytes. It would be nice if Bacula could report the true bytes, then we could get an accurate % filled statistic. Sometimes, I just have to keep wondering how much tape is left and how many more jobs will run on it especially when there is a high compression.
