Below is an extract from one of the reports Amanda generated: ------------cut-------------- Total Full Daily -------- -------- --------
Output Size (meg) 3132.7 3132.7 0.0 Original Size (meg) 4377.7 4377.7 0.0 Avg Compressed Size (%) 71.6 71.6 -- ------------cut-------------- Am I correct in thinking that this run it used 71.6% of the total amount of tape, also the compression doesn't seem that much (used hight-tar with best compression) If the tapes apparently capable of holding 8.0GB (DDS2) at a 2:1 compression rate, the above seems that its not really compressing it at all effectively. I have chosen to turn of hardware compression as well. What would be the best option to use for as much compression as possible? I know that trying to compress already compressed files can increases the output, but this way I have to watch what I put in every directory. and ------------cut-------------- HOSTNAME DISK L ORIG-KB OUT-KB COMP% MMM:SS KB/s MMM:SS KB/s heimdall /scripts 0 10 32 320.0 0:00 103.9 0:01 45.7 idun -/downloads 0 10 32 320.0 0:00 432.6 0:01 61.8 ------------cut-------------- Again for this it seems that rather than actually compressing it, it has increased the original file in size (the scripts directory are only perl scripts and downloads are just a mixture of stuff). Would it be best to use non compression for these types of files? Mark -- --- To steal ideas from one person is plagiarism; to steal from many is research.
