Electronically all must be kept for 7 years and some for 15 years due financial transactions (bank guarantees, contract documents, letters of credit etc.) .. I hold printed copies at firm I work at, and they hold electronic backups in USA/UK/Cz, but these are only 'final copies'. ** The 40 year legal requirement documents I hold as hard copies, but that is only a few documents, say a couple of dozen pages A4 or letter. Arbitration and legal shoots outs need logic and working copies stage by stage, these are on my machines and on my external hard discs and previously on the WD machine as working copy. My copies are in case of a legal shoot out with the company I contract to. I do not want to lose a (say 5 million GBP) Professional Indemnity suit. My insurance costs would go up! Example: I refused to sanction or accept a contract wording. However by underhand methods the sales guy [desperate for reward or?] engaged the company to a Russian Client with real bad terms. My back ups showed I had not sanctioned the wording or bank guarantee wordings, my work machine showed same but a legal department had hard 'signed' copy showing contract sanctioned and accepted. (Umm! don't ask!) Losses now in multi millions to date. Russian work is not easy. So I exercise a degree of caution. Of the work machines at home, all have both MS Windows 7 and 'MS Outlook' and Linux installed one as dual boot and two as virtual machines. My client company is 'tied' to MS outlook as main communications tool (upgrading slowly from XP to windows 7 over 4500 seats!) thus my use as MS Outlook 'winmail.dat' forwarding does not render well in Thunderbird. I can segregate out but easier to use MS Outlook to save the forwarded attachments to my computer documents, while replying from Thunderbird. In reality, I have separate 'images' of machines monthly in case of hard disc failure inside machines. This also saves fixed date documents etc. However I found the WD type disc useful as a second line back up while working on documents. Remote access was available but never used. I would not set up remote access over internet up again. As my 'paid work' is inside MS OSs that is where for accessibility I would want main document working back ups to link to. I connected the WD to a spare ethernet connection on my BTHomeHub 3 and it was usable. Linux machines are on OpenSUSE 13.2 as OS. Knoppix as live USB and DVD PS my introduction to Linux was use of Knoppix from floppy discs on Soviet computers to get a workable system I could use when in Soviet establishments, so I have a 'soft spot' for Knoppix. WD state. " Were you able to retrieve the infofrom the failed WD by the way, or is it totalled?"No data recovered via Knoppix. No 'handshake' with GParted in or out of case when stripped. Disc rotated. I have other backups (and the source machines still) so can be reproduced. Sorry, long and rambling but gives you background.Wow, your job sounds pretty interesting - sort of thing that would make a good conversation in the pub; "You do what?!" Long story short, Simon was pretty much right: set up a VM, install Linux and use backuppc or a bunch of homecooked rsync scripts and you'll have rotated automated backups of all your stuff. Test the restore functionality before settling on anything: all backup solutions are only as good as their ability to actually restore your files when needed.
<snip>Can just ask what is probably a very basic question here. I notice many experienced folk recommend setting up a VM for the backups. Why is this please?
Many thanks roly :-)O yes, and Eion your job sounds very interesting - perhaps you should write a book! haha! :-)
