      I can still recover my files from my ZX Spextrum (and my sinclair +2). These files are from 83-93 (I switched to PC during 1993), some of the files from tape, other from disquettes

      Among these files, all my programs on HP48SX (and my home made kermit transfert system for Spectrum) and some other.

      Well, the fact that both my Spectrum 48K and my Sinclair +2 still work do help.

    Over time they've been migrated with the rest of my data through various 8, 16, and 32 bit PCs, and currently reside on my x86-64 Fedora box. The original hardware is LONG dead. I could probably get them natively off anything going back to my Model 4P, but that would be annoying and require using an RS-232 cable.

      Yeah, I've got a box of punchcards - basically a dump of Basic - for a CDC Cyber system running NOS/BE. In theory, if I ever find one, I can load them up and run batch basic.

      • Punchcards should be easy. You don't need the old hardware. Just a scanner and a bit of software fun. Even if all the specs are long lost, it should be quite easy to rederive them all.

      That's the key; every time you change storage technologies, you have to move your existing backups to the new one. That helps in a bunch of ways:

      1. Media degradation: You're constantly refreshing data to new storage, so the eventual failure of old CDs/tapes/drives/etc is partially mitigated (you still want redundant backups, of course)
      2. Obsolescence: Trying to get that old 8" floppy working can be a pain in the ass; you're either hoping the old machine still boots and has some way of transferring the data once it's read, or you're searching for drivers for an 8" drive on a more modern machine. By transferring immediately on upgrade, you skirt most of those issues.
      3. A little extra redundancy; if the new storage fails, at least you have copies of a lot of data on the previous generation of hardware.

      It's one of those things that you only need to fight with once before it becomes ingrained; I can only go back to c. 1992 in recovering my personal files, because that's when I first went to get an old file and struggled being able to recover it. Since then, copying everything to new storage as it arrives is de rigueur.

      Likewise, at the tech places I've worked for the past 10+ years it's been mandatory to copy all old data over to new storage technology as it arrives.

    I have disk copies and files from my IBM PC in the 1985 time frame. That's the oldest data I personally owned/created that I have records for; prior to that it was TRS-80 BASIC on cassette tapes and extremely hard to retrieve/use. I've got it in my permanent data archive, which is sometimes fun to browse around and see what I was doing 20+ years ago.

Attach the disk, the scanner, the optical drive or the tape drive and chances it will just work.

      Nah, that's easy: 8-bit emulators can often load cassette files through a PC sound-card.

      I was going to try that but I think all my old Sinclair tapes got thrown out a couple of years back.

    • Agreed, I have DVDs, from 10+ years, CDs from 15 years ago and floppies from 25 years ago that work fine. All that's in my archives are email and personal source code from when I was fiddling around trying to learn a few things, nothing too interesting. Don't even know why I keep it. Source code from when I was a kid is fun to look back at, I kept all of my iterations so I can track what I was learning, but nothing too useful and certainly not very relevant today.
    • I find your comment about ancient somewhat troubling. The writings of Confucius or Aristotle are ancient. Of course, most of the stuff we keep on computers is not important but there are some things that we want to recover. Some stuff might be quite valuable. Yes, the pace of technology is very quick but that is irrelevant to the value of a file.

        But you are talking about analog kinds of "ancient". It's kind of like how a year to us is 7 to a dog, a digitial year is like 100 analog years, so that 20 year old tape backup is similar to a 2000 year old analog backup, ie: a 50/50 chance it will work.

        Indeed. That's a challenging one to solve. I personally try to use documented file formats where possible, but that really only solves the easy portion of the problem. The other portion is accessing those files later on, assuming they're not wiped out in some fashion at a future time.

    When I was in graduate school one of my tasks was to read old astronomical CCD images that were written on magnetic tape (and there were a lot of them, since my advisor had been testing CCDs for the Hubble). So for a couple of months I sat in a small workroom with the department's only working Kennedy drive reading tapes.

    Because of age and prior use, many of the tapes were shedding oxide, making the drive rock back and forth over many segments in an attempt to retrieve the blocks thereon. After every few tapes I had to wipe the oxide from the read heads. Then, just to make the process a little more tedious, the data itself had to be byte-swapped. As a reward for all of that, I found one image to use in my dissertation.

    The data was written to CD-ROM in the late 90s, so I expect there's someone right now trying to figure out how to read the data off of the decade-old, decaying archive. If they're lucky, they'll find the backup DATs in the filing cabinet and the last working drive in the department.

      he built a room-sized oven to slow-bake the tapes to re-activate the adhesives that had broken down, otherwise he'd destroy the tapes and mess up his only working machine.

    The last time I needed my resume' was in the mid 1980's. Therefore, it was stored on a 5 1/4 floppy for my Commodore 64, in "Speedscript" format. After getting the Speedscript word processor loaded into the C64, I saved it as "ASCII" in a SEQ file. Then I booted "HDD64" on an old P200 PC, and connected the 1541 drive to it, thru an "X1541" cable. Once saved to the PC's HD, I booted Windows 98. Once done, I brought it across the LAN into my WIN2000 box, and then re-worked it in MS Word 2000. That is the format it remains in until WORD becomes obsolete! ;)

    I had typed Speedscript in, byte-by-byte, from a COMPUTE! Magazine article, years before. For a 6K (yes, six kilobytes) program, it did an absolutely outstanding job! I used that program more than any other on my C64 for years.

    Last year I got given a QIC-150 tape written in 1995 to see if I could recover someone's old email archives. First I had to locate a QIC drive but a bit of hunting on the local Freecycle group got me an external SCSI unit weighing about 40 pounds with a tape drive and a full-height 500MB hard drive included. The tape drive didn't work, in that it talked SCSI-II all right to the BSD box's controller and the motor went round and round but no data came out.

    The first inkling of bad news was realising that someone else had been into the tape drive mechanism before me when I saw the chewed-up screws holding the covers on. The really bad news was seeing the capstan roller on the drive -- or rather the motor shaft where the capstan roller used to be. It had gone missing sometime in the past and the bodger who had been in before me figured that a bunch of rubber bands would make a suitable replacement for the roller. This was some time back, judging by the condition of the rubber bands which were now a sticky mess of perished semi-liquid rubber.

    I rummaged in my junkbox and pulled out an old lump of solid rubber, a platen roller from a daisywheel printed I had junked decades ago. I measured up the motor shaft, made some educated guesses and machined a replacement roller on the workshop lathe. After degunking the motor shaft with a scalpel and needle files the new capstan roller was driven into place and after that the data came pouring off the tape like it had been written yesterday as good old-fashioned CSV-delimited tarball archives. The owner of the tape got back the first emails he ever exchanged with the lady who he had since married and there was much rejoicing.

    As disk is cheap, my data has basically moved with me. Anything that I need that I'd have to go back in time is just dated that way (GnuCash, financial reports, etc.) and still on my current hard drive and daily/weekly/monthly/yearly grandfathering backup.

From there, I had to put them on an 800k floppy, then put said floppy into an old Mac (with IIgs disk format support) that had ethernet on it and a drive old enough to support 800k floppies. From there, I was able to pull it over the network

    I started making regular backups onto tapes when I got a bargain on a QFA-700 tape drive in 1992 that used DC5150 and DC6250 tapes. I transferred these to CDR in 2000. These I can still read. Have not tried the tapes but do have 3 of the drives with which to rely on. I do however have 5.25 inch disks from my Apple II that were last written to in 1982 and still readable.

    Device Side Data's flagship product is the FC5025 USB 5.25" floppy controller. The FC5025 plugs into any computer's USB port and enables you to attach a 5.25" floppy drive. Even if your computer has no built-in floppy controller, the FC5025 lets you read those old disks. And it's not just for IBM PC disks – it also understands formats used by Apple, Atari, Commodore and TI, among others.

(If the stories we've all heard are true, MBASIC-80 was originally cross-assembled on PDP-10s, starting at Harvard before Microsoft was founded.)

    My oldest would have to be building an entire PC out of one of my "junkers" to save and restore an entire DOS 3 OS. At the shop I was working at the time this guy comes in in a panic and says 'Please tell me you have a machine that will run this and know how to set it up?" and he pulls out this big ass old ISA card. It turns out his dad owns a big lumber company and they had this big contract that required some custom columns as part of the deal. Wouldn't you know it, the first time junior talks his dad into taking a vacation and letting him be in charge the computer that controls the lathe that makes the columns shits itself and dies. Now this thing was older than dirt and from what I found out later these machines cost anywhere from 75k UP, and naturally the company that made it had been out of business damned near 15 years, so good luck finding a way to upgrade.

    So when Doug the boss tells the guy "We don't have anything that old on hand, I can get you one in about a week" the poor kid looked like he was gonna cry. He had been to every shop in town and got told the same thing and the job had to be DONE in 4 days, or goodbye big juicy contract. The kid knew that any chance he had to take over the business was going up in smoke faster than that old 10MHz Intel that had been running that lathe. So needless to say I thought the kid was gonna drop dead from a heart attack right there when I looked over from my spot in the back and said "Hey, I think I got a couple of boxes that'll run that at home." The kid was like "I'll pay, extra, overtime, whatever, but I HAVE TO HAVE it ASAP!" So I swung by my house while the kid waited there ready to crap his pants, because he was sure I'd come back and say I was mistaken, but no. I have always been a pack rat and can't stand throwing out working gear and still had my old first gamer PCs, one a 100MHz that I used for the first DOOM, the other a 233MHz with a Voodoo 1 that was my first Quake box, and both with ISA slots.

    So I have the kid fetch the dead box, which was so full of sawdust and gunk it was a miracle it had lasted that long, but lucky for him the 20MB HDD (yeah 20MB, they don't make them like that old heavy dinosaur anymore) would still spin up, so I worked through the evening cloning the DOS 3 install to the 2 drives, getting DOS drivers for the hardware, sealing them so the sawdust wouldn't get sucked in etc. By morning they were done and I was out there setting up the lathe as well as showing him how to spin up the spare once a month so if it happened again he would be able to just pull the first and not suffer any downtime. When that lathe fired up and started cutting those columns that kid jumped a good 3 feet in the air and you would have thought he won the lotto. Good thing I still knew my DOS huh? Anyway he ended up paying me nearly $500 for the nights work, another $300 for the boxes, and at the end of the week when the contract was completed and daddy was back running the company he walked in and handed me $500 and told my boss "Don't you let this one get away, he really knows his stuff!" which made me feel nice.

    And the moral of the story is this: If your company depends on something funky and old to function, have an emergency plan, okay? I ran into the kid at the local mall about 6 months ago and asked how it was going. He said that he fires up that 233MHz every month just like clockwork as I taught him, and has the OS image put up in several places on several mediums like I taught him, but that 100MHz is happily working 8 hours a day, 6 days a week. It kinda gives me a warm fuzzy to know the first box I hunted CacoDemons on is still working like a champ. Some said I should have reamed the kid on the price, since he needed them so much, but by being square with the kid not only did we end up with the job modernizing their offices, but they probably threw us another $10k-$20k worth of work for businesses and families that were connected to them. So it pays in the long run to treat people with fairness, and not try to gouge them just because they are in a bad way.

  • There is nothing from 10 years ago I can't use now. In fact some of my CD-Rs are older than 10 years old. If I wanted to I could boot up my old win 3.11 machine and put data onto my newer machines over the network and that's over 15 years old.

    There shouldn't be any reason to be concerned about 10 year old back-ups unless it's important data, you have one copy and it's backed up onto something that's not known for lasting or is stored poorly.

We had a network of BBC Micros and Masters (which used Econet networking), and in those days had an SJ Research fileserver, which had a hard disc plus two floppy drives. A friend and I wrote a multi-user dungeon to run on econet.

    So a couple of months back I received all the floppies, written in 1989 on the SJ fileserver, which used a filesystem called MDFS.

    Really? The "Y2K non-event?" The only reason it was a non-event was because thousands of us put in a lot of hours making it turn out that way. I worked on a project that, if not tended to, would have been the end of the company using the software and databases in question. That would have definitely been an "event" for them and all of their employees and customers. I'm always a little perplexed by the glib dismissal of that period, but especially so here in this particular venue.

    I must comment on the synopsis of this story. y2k was basically a non-event because thousands of people like me worked our butts off for a couple of years to bring forward our legacy systems and come up with creative ways to do so.

    It gets my goat every time I hear somebody who wasn't involved say such ridiculous things.

    I've still got backup from the early 80's. For example those one disk, 5.25 inch self-booting, games for the PC. For example Karateka [youtube.com]. I have them stored in Copy II PC [wikipedia.org] image files.

    The reason I still have them is due to data migration. Once a new technology came out I shifted my backups forwards. Luckily the data density usually went up quite a bit as well so I wasn't stuck with (relative) big backups.

    For 'Karateka' my migration path was as follows:

    * I had it 1:1 on floppy (360 KB)
    * Transfers via Copy II PC images to 3.5 disks (1.4 MB)
    * Later I got a 20MB harddisk and a QIC-80 [wikipedia.org] tapedrive. So they landed on tape.
    * Then we got ZIP drives (100mb). However the 'Click of death' [wikipedia.org] issue had me looking for something else.
    * Then my first CD recorder (650mb). Here backups started becoming big because I got access to the Internet (early 90's). I had a lot more stuff I wanted to keep.
    * Forward to my first DVD recorder, where I started migrating a lot of stuff from CD. Thanks to Daemontools and CloneCD I was able to copy a lot of CD's to image files.
    * From DVD's (which took forever to burn) I went to harddisks in USB housings. To save time mostly and due to DVD rot [wikipedia.org]. Also I used a lot of very cheap DVD-R's, so data retention was up to 4-5 years on some batches.
    * Now I'm trying to go from USB housed HDD's to a RAID-5 file server. Mostly because my external drives go up to 1.5TB and I don't have double backups on non-important data but I'd still like to keep a lot of stuff more 'safe'. 1.5TB is a lot to lose in one go.

    The only 'trouble' I could run into now is that my oldest files are in archaic data formats. Luckily I kept all the utilities needed to access them. Think Copy II PC and the compression utilities I used at the time:, ARC, LHA, ARJ, ICE, UC2.

    So for long term backups I give this advice:
    * Migrate your data
    * Keep multiple backups
    * Make sure you can access your data formats
    * Keeping backups is expensive. Consciously decide what you want to keep.

    Also a useful tactic is to copy data between friends. (This is what I did when I was young). That way there's always somebody who still has what you want.
