You're right, of course, but it seems likely that whether the disks get a dose of 110/240 AC or not depends on the brick's design rather than the box itself. This is best checked out by opening up the brick and seeing how it prevents mains AC from connecting to the DC out lines when it gets melted. IOW did they get lucky during the El Reg demo or are the disks always saved from electrocution?

It took me about 3 days to write scripts that do do file copying automatically across continents with ssh, email log files with sendemail, etc etc etc. I'm afraid this doesn't fit what I'm after - which is a proper network filesystem that is suited to android and chromebook clients Ok - picture this. I got ssh server running on SSD which consumes less power. From any Linux computer from anywhere in the world, I can run Ubuntu and in nautilus set a book mark to open it as if it were a local storage. I then copy paste as needed. Linux also has rsync which is better than file copy because it avoids duplicate file transfer and can compress files on low bandwidth links. Also it can be set up with cron jobs to do sync operations frequently if needed. Or do it more cleverly if you wrote a script that checked first for changes to the file system and did an rsync when there is a need (which is what the gambas script does). I think what you are saying is you want to be able to do the same from Android and Chrome books? Then that problem is down to writing applications that can do that surely? Windows can use winscp to transfer files in a similar way to nautilus. I'm sure android must have. And so too chrome books. And I believe they both also have rsync. Again its all to do with writing applications (which probably exist any way). So, in the open source world, the cloud storage solution already exists in the form of ssh server which you can set up at home. The next thing are the applications needed to access it for the various clients that need the access all of which exist in some form or another. The last part of the problem is clever applications that only do necessary and minimal transfers - which is probably the bit 'cloud server solution providers' do differently and better to differentiate themselves. The solution with ssh servers is better than dropbox because the server is not entrusted to third parties. Dropbox in the USA can be served with secret gagging orders and the data stolen by NSA trolls which has so far resulted in two thirds of USA vendors of IT kit being de-listed from governments around the world - all thanks to NSA trolls. The system of legalised secret gagging orders and secret data theft by unsupervised trolls in government means public cloud storage is not viable for any kind of sensitive data such as employee records to commercial engineering informaton. Cloud storage is good for marketing and web content that is intended to be seen. |

What happens when an asteroid takes out your house at the same time as one takes out the public cloud server? There is physical serious separation between the mains and the LV on any modern PSU. Line several mm of plastic bobbin at least. And the PU needs to be working properly in order to deliver ANY volts to the secondary of the transformer. The chances of overvoltage are approximately zero. It's sad that the fallacy of the precautionary principle, that any possibility no matter how remote, must be considered and have huge sums spent on it in order to satisfy the idiocy of people who don't understand technology and science has transferred itself from climate change to backup policy for computer systems.

Could you suggest any? https://www.boxcryptor.com/ Haven't tried it, someone suggested it recently and it looked interesting because I had been considering doing that myself. Not that I have anything that matters much on any cloud, more just as something to suggest to those who refuse to use a cloud under any circumstances because their stuff isn't secured. Some are surprisingly paranoid about them. I do use them myself, but just for completely automatic availability of stuff that I do use on the phones which is almost always prepared on the desktop systems, mostly extracts from the databases of stuff like clothes sizes, best prices I have seen for stuff I buy much of etc. I am genuinely interested - I couldn't locate any with much googling... Haven't tried looking myself, but presumably putting that rather unique name should show some competitors. I'm also looking for an RSS reader that can prefetch the linked story as a web page and cache it - to deal with the spectacularly poor RSS feeds on british media that put about 1 sentence in the RSS description! Don’t do that myself, I use the podcast system on the phone and our national govt radio broadcaster for stuff to listen to when walking for exercise. (There are quite a lot of things that I wonder "why does this not exist"? Yeah, I just discover that the phone won't do video with no audio, you have to post process and strip the audio, pretty crude. I guess I should brush up on my Android programming and write one... Trouble is that that can be a lot of work. The only game I play is Freecell Pro and I'd love to have that on the phone, but it’s a lot of work, particularly for the solver that that has. I did dabble with hacking on some open source app once - an alarm clock. I've done that with Win but a combination stop watch, count down timer with the commonly used times as buttons. Better than anything I can find for the phone which I do use for some stuff I do quite a bit like the spirits distilling which has some rather complex timer ops but haven't yet got off my arse and done it for the phone which would be the most handy when doing the distilling. I managed to hack on the features I wanted (and offered them back to the author). Trouble I found, apart from having to run up that monstrosity, eclipse, is there is a bugger of a lot of stuff in even a trvial app just to make the very basics work. Yeah, that's the problem with Freecell and the timer, and it irritates the hell out of me that it shouldn’t be necessary to do all that again particularly the basic user interface stuff that you need with the phone. |

The server itself would be ssh, and the primary method for file transfer would be rsync. Easy enough to do, but you might have to pay someone I did my automation tool using Gambas over a couple of days. May be you can give it a try? Its not that difficult. And it does have a non-GUI mode for writing applications that run as servers which start up when the machine boots. |

That's certainly the right question to be asking. I thought someone had wanted the NAS and it's PSU to be usable after the fire, but rereading today I can't find it. I would hope the NAS had some serious crowbar protection on its incoming DC in. Indeed so ... and on the ethernet and USB connectors, though the power input is more likely to cause trouble. Ethernet is pretty bomb-proof by design. USB is very much a weak point. There nothing bar a simple polyfuse protecting the +5V line, and the I/O ones are totally vulnerable. Indeed, recently I read about some b**tard designing a device - masquerading as memory stick - that keeps pulsing these with a very high voltage, resulting in severe MB damage Yes - and think of the effect of a good, hot fire on the rats-nest of cables under the desk behind the NAS box. Who's to say that you wouldn't get 240v on the CAT5 or a USB cable? But, I wouldn't expect the motherboard to survive the file: it looks to be outside the fireproofing wrapped round the disk, so with such a design you can do all you need by putting a high voltage shunt across the SATA leads as they enter the fireproof disk area. OK, just heard back form Trevor Potts and the ioSafe guys. I asked: "When the PSU shorted out due to the fire, could it have fried the disks by letting AC get into the NAS box or does it have designed-in features that would prevent this happening? As it looks, to me anyway, like a standard laptop power brick, this seems like a reasonable question. I'll be very interested to hear what you have to say about it. " And the reply from ioSafe is: "In such an event, the worst case scenario is that any data in transit would be lost. The data on the drives would not be lost. " ....so it looks as though they've thought about this problem. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |

What stops it frying the disks?" |

I wrote: "The scenario I'm interested in is where there is the usual rats nest of cables behind the 214 and the fire gets into this, melting or burning insulation so a live mains conductor contacts a wire in any of the CAT5, USB or DC power cable so that mains voltage gets into the 214's PCB. Is there anything in the 214's circuits that would prevent that frying the disk drive electronics? " and the reply was: "As it happens, burning the cables is no more likely to result in data loss than simply improperly pulling the plug. We actually perform our fire testing with the units plugged in and powered on. " So I guess you'll draw your own conclusions. I'm out of this thread.

I can't speak for "the cloud" in general but OneDrive synchs on all computers on which the client is installed (you don't need to install the client to use the service--you can also access it using a web browser and download whatever you need but you lose the transparency), so for all my OneDrive files I eventually end up with four copies, one on my workstation, one on my server, one on my laptop, and one at Microsoft. Which unless Microsoft decides to screw me over with my own data, is actually a pretty good arrangement--it would take a fairly substantial disaster to lose all copies. |

One copy on every installed computer and one on their cloud servers. Exception is mobile devices which download on demand. I believe the android client will let you specify particular files to keep locally. |

I will tack this here since I have not read the thread yet, and may just be repeating what is elsewhere. Have you looked at the Netgear ReadyNAS with cloud integration? That basically does what you describe where the cloud storage is your nas device, and remote access to it is possible via the web. The only bit I am not sure about is specific clients for the mobile OSes. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

OK - I'm interesed - please tell me more. What client are you using and can it offline sync certain files? ES3. Maybe I'm not clear on what you want. ES3 allows the devices to mount Samba shares. Thanks - that might be worth checking out as a general file manager (I am using "File Manager" right now). I use ES File Manager. That also has no difficulty browsing NAS volumes etc via SMB/CIFS I have managed SFTP access with mine - but the main sticking point is you cannot mark files for offline access (aka Keep on Device"). The whole "mount SFTP/SMB" thing is an acceptable last resort - but I really would like to have user selectable caching as that makes a big difference in usability if the network goes away. To be fair I have not tried that with mine (the phone is old and slow!) -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |
