Yesterday I picked up an Apple Timecapsule 1TB, the plan being to have live backups of both my and my wifes computers (losing all of those baby/wedding/etc photos would be a disaster). I will also use it to put the colour printer on the network and my 500GB WD drive, which is where I will be keeping media for the time being.
Initially I plan to set it up as a N only network and my other access point as B/G only (also on a totally different channel) so that essentially only our laptops will connect to the time capsule and supposedly at N speeds making the backups and streaming better.
Eventually I will buy a Drobo and connect that to the time capsule and have the time capsule back itself up to the Drobo periodically, so I will have backups in two places. I also have copies of our photos stored in "The Cloud", so hopefully we're covered for a rainy day. After all as the quote goes, there are only two types of people, those whose disks have failed and those whose disks will fail (or was it backups?).
I havent done anything with the TC just yet though, last night I was consolidating data from various drives onto the WD drive and watching a film, for the first time in a while. Tonight I will hopefully get time to set it up and test it, so I'll let you know how that goes.
