Neither RAID or rsync provide "data security".. in fact no tool or hardware does, that's a very dangerous mindset to adopt.. deep trouble ahead .. now, that being said.. RAID can provide you much better *availability* and disaster recovery aid when things go wrong, but there is almost always a tradeoff for performance.
performance doesn't bother me in this case, so i would be willing to accept that trade-off.
It is not a replacement for backups, that's when rsync comes into play to help the file transfer/sync process.
so you also say that, if only one can be adopted at this time, backups (rsync) are more suited to prevent data loss. what i was considering was replacing these regular backups by RAID1, mirroring the whole disk, which obviously contains a copy of the data, too.
"data security" involves a "process" not only "a bunch of hw and software" but also policies regarding physical/virtual access to the information, data retention and confidentiality. Yes, cheap-ass hardware fails and usually sucks..but human beings screw things up in a much larger scale..big time! so think before you type !
i did even better, i asked here, with the usual good results -- even if i'm still not sure what i'm going to do in the end. -- phani. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
