If you have N clients all streaming data to a central host, which then has to stream that data to a tape drive, and the tape drive then has to compress that strea; /usr/local/webapp/mharc-adsm.org/html/Amanda-Users/2004-09/msg00027.html (11,767 bytes)
2. Re: enabling hardware compression ? (score: 1): Author: Gene Heskett <gene.heskett AT verizon DOT net>; Date: Fri, 3 Sep 2004 21:41:00 -0400; That, generally speaking, is not true. The compression that tape drives use is typically some form of RLL, and regular RLL encoder/decoder chips right in the drive can handle that without breaking a; /usr/local/webapp/mharc-adsm.org/html/Amanda-Users/2004-09/msg00028.html (14,707 bytes)

You can SW compress on the client or on the server or in the HW having nothing to do with the choice of dump v tar.

Those are actually smart enough to *not* hardware compress incompressible data. So, with those drives, you can actuall mix hardware and softwar; /usr/local/webapp/mharc-adsm.org/html/Amanda-Users/2004-08/msg00220.html (11,825 bytes)
