[Bacula-users] LTO 6 compression

2013-05-07 Thread Alan McKay
Hey folks, I see that LTO 6 holds 2.5T data per tape, or 6.25T compressed. I've never used HW compression before so am wondering whether its performance is variable like SW compression. i.e. depends on the file contents just what kind of compression ratio you'll get. And also how reliable is i
