Re: [Dorset] Should of done a backup - Q1
Hi Tim, They look nice, I agree, but I've an eye on power consumption. Some low-powered CPU with an SSD sitting as a buffer in front of hard disks that occasionally spin up? HP Microserver consumes 29W with disk spinning. I'm paying 12.39p/kWh at the moment, which I think is quite good, so that makes it 29 / 1,000 * 24 * 365 * 12.39 / 100 = £31.475556 a year Not bad. Out of interest, the Crucial MX100 SSD is about 3.4W under load, 100mW slumbering. http://www.anandtech.com/show/8066/crucial-mx100-256gb-512gb-review/8 But you'd need something low-power *with* SSD to hook it up to, so not Raspberry Pi, Pandaboard ES, BeagleBone Black, ... Oh, and cheap. :-) http://www.timj.co.uk/2013/07/building-a-tiny-low-power-linux-nas/ used an Intel Atom mini-ITX board to get 14-15W.

Re: [Dorset] Should of done a backup - Q1
I have a HP Microserver - excellent little unit! :) They come with a single 250GB SATA hard disk and have four bays so you can add up to three more. Mine runs CentOS 6.5 very well, used for storage and as a development web server. The great thing is that, unlike a NAS, I have control of the software and configuration. I paid just over £100 for mine, second hand on eBay. It looked like new and the SMART values on the hard disk suggest it had had under 200 hours use. Paul.

Re: [Dorset] Should of done a backup
You can clone the disk yourself if you have a new drive e.g.: dd if=/dev/sdb of=/dev/sdc Or create an image on a larger disk e.g.: dd if=/dev/sdb of=/mnt/newdisk/image dd does a low level copy so it should copy the partition table and any recoverable data.

Or ddrescue. Method of use is similar to dd but specifically designed to recover failing disks. Yes, that's very good and has only got better since I last used it. It reads through the disk once, copying what read OK and making a note of the sectors that failed, then it goes back to tackle them with various strategies, e.g. approaching from one direction then the other. Needs a bit of study to understand the options. That's GNU's ddrescue(1) we're talking about; package gddrescue on Ubuntu. http://www.gnu.org/software/ddrescue/ The package ddrescue, no `g', is also on old Ubuntus, e.g. 12.04LTS, is a variant I've no experience of that contains the dd_rescue(1) command. It has been dropped in later Ubuntus.

Hi, Tim wrote: I was thinking about removing the hard disk and putting it in a USB disk reader and hopefully recovering some or all of my data Be sure to mount any partitions presented as read only. Even if you think you're not modifying the files there's still filesystem meta-data, e.g. how many times it's been mounted, when, when did you last access these files to look at their contents, and if there's a risk the drive is flaky then I'd prefer to avoid writing. Charles wrote: The problem is, the WRITE is was still faulty, so lots of my data - mostly irreplacable pictures taken from around the world in my extensive travels - is now shredded by wide bands of angled stripes. A hair-tearing situation!!! Wonder if this was introduced when they *thought* they successfully copied the data off of the drive. Sectors that couldn't be read may have resulted in holes of noise in the files? Extremely daft for them to write at all to suspect drive, especially making it the only copy of the data. Writing to two independent drives but reading only one may be the best protection against this type of failure. Things like Amazon Web Services and Google Drive offer storage, but they're often quite expensive for lots of data. There's also Amazon Glacier which is quite a lot cheaper, but look out for the retrieval charges. It's intended for data that's rarely accessed or retrieved, e.g. a listing of what's there can take a few hours to be delivered. It doesn't present files and directories like you're used to. Instead, it's normal to upload large archive files to it, e.g. tar file, that contain the directory structure. http://aws.amazon.com/glacier/ Various clients exist for Linux to make using it that bit easier, including GUI apps. Here's a random sampling. http://blog.tkassembled.com/326/creating-long-term-backups-with-amazon-glacier-on-linux/ https://github.com/vsespb/mt-aws-glacier#readme http://www.crossftp.com Cheers, Ralph. -- Next meeting: Bournemouth, Tuesday, 2014-09-02 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread on mailing list: mailto:dorset@mailman.lug.org.uk How to Report Bugs Effectively: http://goo.gl/4Xue

Re: [Dorset] Should of done a backup - Q2 - DVDs
Hi Peter, At how old should I be 'refreshing' or duplicating my DVD backups? Format shift quite often, I would think. That said, I've some 5¼ floppies to access one day. Rob Pike recently wrote about the topic and the value of real photos tucked away in a shoebox for your descendants. http://commandcenter.blogspot.co.uk/2014/08/prints.html If archiving data, you could consider generating error correction codes yourself, quite separate from whatever the media might be using under the covers. par2(1) was one program to do that. http://en.wikipedia.org/wiki/Parchive Then again, Olly did PaperBack, a program for printing data onto paper for later retrieval by scanning, again using ECC for coping with the odd coffee stain. I fear data density may not have kept pace with data growth, though with another data deduplication... http://ollydbg.de/Paperbak/ Cheers, Ralph. -- Next meeting: Bournemouth, Tuesday, 2014-09-02 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread on mailing list: mailto:dorset@mailman.lug.org.uk How to Report Bugs Effectively: http://goo.gl/4Xue

I have rebooted it several time via turning it on and off but that made no difference, there is a blue light that come on and occasionally flickers (which is normal). I have tried to access via Linux and Windows, windows has Lacie disk manager program but that claims there are no disks. I have done an ipscan and can account for all the IP's addresses listed, none of the Nas, (both window and linux picked it up by device name and I cant remember the IP address I set it to). My main question is what file system do those device normally run. I was thinking about removing the hard disk and putting it in a USB disk reader and hopefully recovering some or all of my data (making the assumption that it is the Motherboard as such that had died and not the disk). I do have a backup but not a current one, in my defence the USB hard disk I was backing up to died and I have been saving to buy a new nas (as I am currently using 400gb of the 500gb nas disk) and a new usb hard disk to back it up to. Any suggestion or comment appreciated, except those that extract the urine ;) Tim -- Next meeting: Bournemouth, Tuesday, 2014-09-02 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread on mailing list: mailto:dorset@mailman.lug.org.uk How to Report Bugs Effectively: http://goo.gl/4Xue
Re: [Dorset] Should of done a backup
The ZyXel NAS unit I had a while ago used Linux (ext3 I think), and the disks could be accessed by a Linux system (or with DiskInternals Linux Reader on Windows). Fingers crossed it is the NAS and not the disk. Paul On 13/08/2014 17:17, Tim wrote: I had a Lacie single disk (500gb) nas but for the last few days I have not been able to contact it.
