But at least if you have an offline backup (plus one or more offsite copies to be really safe), you can get your data back in the event of catastrophic failure, malware attacks, hostage situations, etc.
It doesn't cost you anything - I use the same adblockers on my web browser (at home) - I very rarely see any advertizing at all, but it's the principal of the thing - if you didn't have any tracker blockers attached to your browser, they'd (advertizers) be having a heyday, and nothing makes me more furious than having my privacy invaded by some machine that thinks I want to see advertizments that I have absolutely no interest in at all! If I want something, I go and buy it - I don't wait for some advertizement to suggest I need it or whatever - I actually don't use the web that much, more VPN and usenet - so sick of the commercializm, I remember when we first started web surfing back in the early 90's and it was so nice because it had no advertizments - now that is all it is, why bother?
Then you will find a new one and backup to there instead. If you and the backup are nuked then it either doesn't matter or you fall back to another backup.
But as stated one backup hdd in a fire safe is not a good backup whatever you say.
I've never been convinced about that.
And it depends on the
You don?t see the same problem with hard drives as the backup media.
Just someone's scenario which isn't very plausible at all.
Because it leaves all the other sources of information for dead convenience wise.
This is cool (actually hot)!!
When someone takes one to bits can they look to see how they ensure mains doesn't get across the disks when the psu melts?
The PSU looked like an external laptop brick to me, so the answer would be inside that.
Who needs a fire? I once had a power supply spontaneously commit murder/suicide while I was using it. The machine just quietly locked up - but the motherboard and both hard drives were destroyed. And I learned the hard way that my backup procedures were inadequate...
Well it might not be, you would want to protect your valuable assets that you went to the trouble of buying a fireproof device for.
I just wondered what this protection was, it should protect against anything that could damage the power brick including: fire, water, crushing and probably incompetent users.
... but it obviously didn't protect the brick against fire, etc., judging by the nicely actinic flash when the fire got to it.
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? I've just passed the question on to Trevor Pott and will pass on what he says.
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.
The PSU can burn because you buy another.
The NAS itself is (mostly) trashed by the fire, but you can take the drives out an put them in a new NAS and read the data.
The idea is to protect the things (data) that can't be replaced, but simply to replace the things that can.
No - I'm not.
My idea is a "disconnected aware" network protocol and client combo.
I cannot rsync all my stuff to every device because the clients don't have 3TB of storage.
An ssh server is *adeqate* but not great. It does allow me to access any file securely on demand.
However, I've not found any clients (yet) for Android that let me choose to cache offline copies of selected files or directories nicely.
Also the SFTP clients don't really integrate with Android.
This scenario:
"I'm going to see Joe and he wants to look at the pics of Prague I took last month. And there's no Internet down the pub where will will meet for beer."
1) Google Drive: I can mark a whole bunch of stuff for offline access - let it sync and off I go.2) With SFTP I'd have to manually copy that over to the phone's storage and any updates on the server would not get replicated.
So Google Drive does it right (TM) but with all the problems that it's not secure (against the NSA/GCHQ etc) and Google could bugger me up. I know this -
So basically, SFTP is "just about good enough" but it's no where near "great".
I believe the point was: what happens when the PSU melts and dumps mains to the output and blows your NAS to tiny weeny bits?
I would hope the NAS had some serious crowbar protection on its incoming DC in.
And almost impossible scenario.
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.
It's easy enough to add that by encrypting it before Google sees it.
and Google could bugger me up. I
I would not call that "easy".
Again, the aim of this is to be user friendly - where the users are aged
9,11 and SWMBO.
There are systems around that do that completely automatically, so very easy.
Completely automatic encryption will be fine for those.
