Just to add my 2c considering I started the other thread, I'm not aiming to replace my backups and data is indeed in three places; My main drive (esata) My backup drive (USB) Another backup drive connected to a computer at my parents place, using crashplan over the Internet. The holes in this plan that I can see are: 1. Bitrot (discussed in other thread) 2. All backups are online. Someone malicious on my main pc could potentially wipe the remote backup through the crashplan GUI. This is a hole I'd like to fix but it may be too inconvenient to fix at the moment. Some form of online but write only storage would be stellar. -Noah On Tuesday, July 1, 2014, <zlinw@mcmedia.com.au> wrote:
I have been reading the "btrfs/ZFS, sans raid and bitrot" thread and a number of thoughts and questions spring to mind.
I get the impression that some are looking for a single reliable storage solution to avoid having to do backups.
Surely this is impossible, I certainly would ______NEVER______ (excuse the shouting) ever trust my life to a single system if at all possible. When one is doing instrument flying training as a pilot you are constantly told never to rely on a single instrument but scan all of them and come up with an overall coherent picture. If one relies in such circumstances on a single point of failure you __will__ kill yourself.
One is told raid or any such thing is a reliabilty strategy __not__ a backup strategy.
I personally keep all data I consider important on four separate systems/devices one device (which is in fact duplicate items but differing technolgies) being kept off site. Maintaining this is a bit of a pain but there is no other way as far as I can see.
The reason for the number of separate backups is we had in one instance in a large commercial situation managed to destroy two backs trying to restore a system. We only succeeded in the end becuase I had independantly duplicated one of the backups on another system.
