Well, it irks me not to use compression on things that can use it. For instance, email and news. Big and/or many text files. Backups are often compressed: tgz, zip, rar... I could instead use rsync on a compressed destination disk. Or dd, many empty sectors.

I think it is both. There is a sweet setting that speeds up the process, less writing. Too much compression and it is slower.
--- If you compress email, it makes grep'ing through it much slower... Really depends on your disks and backup media. gzip -1 ... about best I see is ~50MB/s on compress on a 2.6 GHz processor (from a file in memory to /dev/null). So that's about 20.5 seconds for 1G, or near 6 hours/TB -- and that's not counting "read time" from the source or writing to the final media -- that's just compress time. So one 4TB disk would take a day? Just to compress? Sounds masochistic... Maybe if I backed up to a cloud... but who would trust that ( for reliability or privacy)... -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
