OT - Computer Systems Recovery
Quite a few firms & systems got hit by the hurricane.
It looks like many had no good disaster recovery system. Some may have lost their backups too I'd wager. This includes government Sites. How many firms are now out of business? -- Cliff |

This includes government Sites. How many firms are now out of business? -- Cliff Several of my buds that work for bigger companies that have quarterly "Disaster Recovery" drills that involve a number of scenarios including nuclear attack. In the case of an insurance company, they have facilities that are redundant and actually nuclear proof except for a direct hit. He claims that they could be back in business in a week after half of the US is destroyed. Even my fly-speck company has off-site data back-ups so, I tend to believe that most companies have enough sense to do the same, especially in a high-risk area like NO. Gov, sites have strict protocol for back-ups. |

How many firms are now out of business? -- Cliff Disaster recovery is the number one priority of my job. It's not easy, but it's workable. But all it takes is one day of slacking off and the whole plan is down the tubes. It is a very serious undertaking. We use Computer Associates Brightstor with the DA option which allows me to (using one CD and the latest backup tapes) rebuild any server, no matter how dead it is. We keep an inventory of spare drives and other components in a big ol' vault for safety (along with the offsite tapes that have been returned in the last few weeks) . Believe me, there are so many competing priorities that it would be easy to ignore this stuff but I have been told many times, DR is your number one concern - if anybody comes up with something that interferes with that, screw them. It is something that just requires the unwavering attention to detail to get it done - it isn't some kind of expensive miracle. |

This includes government Sites. How many firms are now out of business? -- Cliff Harddrives are hermetically sealed. If needed they can be overhauled (replace the circuit card) to make them work long enough to recover the data. I tell people to never ever format a harddrive, let the tech do it, but in reallity, I just keep the old drives, because the data is still in them. There are data recovery firms, who can disassemble a harddrive and using lasers, they can read the data strings on the platters, then they can reassemble the data, but that is last resort and costly. |

I've also seen the "drill" look good but the entire thing fail in practice. In one case, the backup software lied about having written the files in the log files. In another, a few sysadmins did not even begin to grasp their own system's file protections. In another, what to back up had to be manually added to the list .... but nobody was updating it & there was no plan at all. Then someone forgot to turn ON the new UPS system .... g. -- Cliff |

How many firms are now out of business? -- Cliff any firm that didn't have a backup stored somewhere deserves the same status as the welfare losers who didn't leave NO. In todays world of (increasingly cheaper) DVD writers backups have become easier than ever to perform. I used to use tapes for all my backups, but now I do it all on DVD. It's so easy I'm astonished that some businesses miss this step. |

I love the magnets, very small and very strong! But they all have had vent/breather holes with sub-micron filters in the top. I suspect that all hard drives are built this way. Take an old one aaprt and you will see what I mean. Terry |

But the drives are supposed to be sealed. No, they arn't. Sealing against 1-2PSI of varying air pressure (as you change location) is really problematic. If it fails, even slightly, then it may suck in debris, not to mention the forces of some 30 pounds or so on each side of the drive distorting it and making it not work. All hard drives have breather holes of some sort, as that way they can filter the air coming in, instead of attempting a hermetic seal. |

Possibly. The better ones would have insisted on flood proof storage. This includes government Sites. How many firms are now out of business? Probably many, but for many other reasons as well. e.g. all/majority of your customers have gone out of business as well and you can not absorb the loss. -- Cliff any firm that didn't have a backup stored somewhere deserves the same status as the welfare losers who didn't leave NO. ROFL, that is probably 99% of them. So, how far away is your offsite backup stored? In todays world of (increasingly cheaper) DVD writers backups have become easier than ever to perform. I used to use tapes for all my backups, but now I do it all on DVD. It's so easy I'm astonished that some businesses miss this step. Wow, your on a real humor run today. Don't give up the day jopb will you. Hint, it isn't the tool that is important, it is how you use it that matters. If a business owner backs up and was able to evacuate and remebered to take family records and his business papers, then he might survive. It doesn't matter if it was on floppy, CDrom, DVD, Tape, Ram Stick, etc, or even paper. I will give everyone a free hint, you plan your backup system to match the disasters you want your company to survive. For many companies, a nuke hitting their city isn't something they are going to be too worried about. Many companies don't plan to survive such events. |

This is incorrect; most hard drives have an air vent with an HEPA filter (often a little felt disc) so the cover doesn't blow its gasket if you take the computer to say Denver after it's built at sea level. Thus if a drive is submerged water CAN enter the head-disc assembly, especially if the drive was at its operating temperature when the machine room got flooded. -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Reply-to: address IS Valid. |
