I have an enterprise wide full backup that runs every Sunday morning. It is about 2 TB worth of data. The first time I ran it as a test with BE 2010 it only used one LTO4 tape. Now the compression rate was an astounding 2:9:1! At the end of the backup 2.1 TB of data was written. It ran the second time and it used two tapes (only a 100GB on the second one). The compression ratio was 2:2:1 on the full tape and 1:6:1 on the tape that only used 100GB. My question is there anyway to specify a job to compress at a higher rate with BE 2010. I am currently using hardware compression.
