    Backup Blues

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I can only blame my self... Lost 5 years of tweaking and setups.....

    IN addition to a week of bashing my head on any number of HDD and the floor.

    1: In search of speed do not uncheck the option to validate or if it is unchecked (often the default) then CHECK and CHECK again and set it to Validate...

    I have always berated and beaten up on so many who loose data and state" I was going to backup".

    I have 3 backups... In three separate locations... And rotate through them about every 3 weeks.... Good and bad...

    I was short some time after having an issue with some recovery processes for another and "turned off the validate option". Shortly after I had a problem or two when doing another recovery and did a restore from image... All worked as expected...

    Time passed ( 5 - 6 weeks) and I noticed performance was a problem...

    I made an emergent image on Saturday... Would attend later.

    Wife rang to say it had a boot problem on Monday last week...

    Yep, sector and block errors.... HD was failing... Thats OK, I have 3 .. no 4 images of my main system.... Data is backed up on a full NAS raid system as well as off line.

    Needless to say every Image I had access to including the last two that I could un-deleat were all corrupt and thus would not restore. Note to self... The corrupt error usually appears almost at the end... Time consuming.

    So after any a large number of attempts, I have given up...

    So I am now trying to reinstall and re load countless applications etc. Needless to say, some I will forget about and others will be lost for sure... Let alone all the web pages and forums etc that I have subscribed to over the years... Yes I have some and some of this is almost redundant as Firefox has addins etc that allow you to sync all all you passwords/ profiles etc and along with G-mail etc some of the day to day stuff is OK....

    It is all the tweaks and setup and keys that will be the main pain in the butt... A week off and 1.5 kg of beans needed... Oh and a dog to kick.. The wife is already complaining that I have not come out of the den for long enough and when I come up to eat... Apparently I just GRUNT...

    ALWAYS check as to VALIDATE your BACKUPS... Do not over right until you have at least TWO good backups... CONFIRMED.

    Hi

    Much of that data is probably recoverable. If its a straight disk image it can probably be mounted and the files read. Certainly the forum files that are plain text.

    I feel your pain AM...

    Similar thing happened to me years ago with Symantec Ghost and backups to CD-RW disks. I actually validated the images before storage but when the crunch came after a HDD failure, my System image kept coming back with corruption errors. So, that was the end of my relying on Optical Disks.

    These days I rely on brand new (external) HDDs which I cycle through the computer after 2 years or so as Data Disks. I think a lot of people use their old HDDs as backup disks but this is a very bad move, even though HDDs are very reliable, using old, tired HDDs for such an important task is fraught with impending disaster.

    Anyway mate, hope it turns out for the best and as Mike says, there are ways to recover most, if not all the data.

    Cheers mate,
    Mal.

    some 50% of the files have crc errors and are corrupt and un recoverable..

    I have my data files ie. Docs, PDfs, Assignments and papers etc along with all my family pics etc...

    It was more that all the reg files and configs etc that are so screwed that I have to re generate... Not impossible but time consuming.

    I do a lot of data recovery and some forensics for others and it is always about the data... For me it was more about having a fully recovered system in an hr or two that was the real issue.

    CD and DVD are good for about 1 to 2 years - Graphics files can some times be recovered b data and exe files only need a bit or two to fail and that IT....

    Image files and updated on NEW hardware.... HDD can be good but not always 100%... Even RAID 5 systems can fail and not be recovered, but at least there is a chance....

    Should be up an working in about 3 days... At present accessing the net via a free wireless ;) connection and a work laptop ::)

    A word of additional caution when relying on optical discs for backups. Cheap/generic discs can become unreadable in as little as a couple of months. Even with big name brands, data errors are not uncommon after as little as 6 months. The brand/quality of the burner you are using will also determine the reliable life span of your discs.

    With over a dozen years of burning and thousands of discs done the best combination has consistently been using a Plextor burner and Verbatim discs. To date this is the only combination that I have found where the discs can still be read error free multiple years later. Even with this combination there is the occasional disc that will have an error. Even if you are using the Plextor/Verbatium combination you should burn a new disc at least every year or two to insure your datas integrity.

    If you want truly archival storage of data you need to be looking at tape backup systems. DAT and DLT type tapes will reliably store data for decades if stored properly.

    I concur and in addition suggest that you burn at a slower rate and then store in a correct manner... After all it is a chem process and light and humidity will assist in destroying that precious data you trying to keep.

    I feel for all those who are archiving Photos and other family keep sakes to CDs and or DVDs... OUCH
