10T Backup Server Project

Play


Craig Severson explained his backup system one time. it seems over the top until you hear, “I can take that drive over there, plug in, reboot and I’m back to five minutes ago.”

I needed a backup device that transparent like Apple Time, was more cost effective then a appliance NAS drive, give me the most storage for my money and it had to be something I could self repair. I ended up building a 10 terabyte server powered by FreeNAS for under a $1000.

the problem that caused the need for this project presented itself in a rude way. a hard drive died inside a MacBook Pro which had a backup but it wasn’t up-to-date. this was caused by the movable nature of notebook computers. you have to remember to plug things in so that other things can happen automatically. the back up drive for Time Machine won’t work otherwise. and because nobody thinks like, “hey, so I’m going to lunch I guess I will plug this in so it will do it’s thing.” we have to make sure that backups just happen.

which brings up an ugly rule: the only time you think about backups is when you need one.

enter the age of 3D printing

Play

my problem with things today is that it’s going to become virtually impossible to play. electronics is a good example. so many of the parts are surface mount only. meaning you can’t just whomp something together on a bread board. but to push the idea even further, there is no way for two guys in a garage to make an iPod. okay they could but look at the skill set they have to have to make it happen.

I read a Rudy Rucker book where lots of the tech is mindblowingly complex. tech that was so hard that a humans couldn’t even be involved after a certain point. yet interfaces to tech creation allowed the characters to control making without thinking about who made who (robot making tech based on human interaction). the book Makers mentions combining complex programming projects into a greater object. this concept of reusing code is tossed out there like it’s no big deal. but fiction always over simplifies making because the story would become boring otherwise. to most people man landing on the moon is a sound bite even though it took the better part of 20 years (don’t forgot all the work before the Kennedy speech) to get there.

I’ve had a lot of printers in my life from letter quality daisy wheels to dot matrix to dye sub to laser. and at some level the businesses I ran wouldn’t have been possible without the leveraged use I got from printing without limits. Tom pointing that this same thing is right here with 3D printing is telling.

1) it’s ground zero. think of MakerBot“>Makerbot as a Epson MX-80
2) there potential for hundreds of new business
3) be prepared to see lots of failure as it engages
4) plastics and resins are toxic. stand by for regulation in California.

taking apart an AKAI M9 pre-amp

it’s interesting to see technology from the not so past. it’s complicated and it’s not. I found reason to what looked like madness as I became more familiar with the layout. sometimes it’s a thing of beauty. but mostly you have to marvel that it worked at all. I am sure that somebody will marvel over an iPod the same way 4o years from now. read article

G4 NAS drive MK3

Play

the G4 machines we used for this project were retired hardware that had been purchased new. eventually they were deemed too old to do day to day work. in addition the machines that were made into NAS drives were passed over for faster G4 macs when a gift or donation was made to somebody who needed a machine. they were pretty much unloved. read article
