I have been using Bareos for a couple years now and Bacula (Community Edition) a few years before that.
One thing that I have never gotten to work is hardware compression. I used to use LTO3 tapes that natively storage 400GB and 800GB with compression. Never got beyond 400GB. I've upgraded by tape library to a Dell TL2000 tape library with LTO6 tape drive. LTO6 natively stores 2.5TB and 6.25TB with compression. Hardware compression is turned on. However, I never get above 2.5TB of data on each tape. I read somewhere that you must spool your data before writing to tape because Bacula/Bareos requires a steady stream for compression to work. Tried that, still no dice. And yes, I have disabled soft compression for my backup jobs. All the documentation I found online are limited and/or out-of-date. I'm presently using 2 LTO6 tapes to complete a full backup (~3.5TB of data). Obviously, my 2nd tape is under utilized and should not be required if 6.25TB capacity is achievable. Is there any H/W compression expert that can shed some light on what is required by Bareos to get compression working as advertised?
