Is that DVD-RAM in an original unopened cartridge only or would you include DVD-RAM without a cartridge if it is handled carefully? DVD-RAM is a good solution, but not as reliable as MOD. MOD is allways with cartridge and verify after each write. With DVD-RAM you get either, but usually not both, i.e. cartridges don't need to be verified by the drive and blank disks need to be but do not have a cartridge. Personally if the disk is handled only with gloves and stored in a dark place, cartridge-less DVD-RAM should be o.k., but note that they only have 100.000 certified write cycles.

oups.com... I am looking for opinions on what a decent tape backup for a PC workstation might be, somewhere around 40 gigs or so, speed is not the biggest issue, mostly being reasonablly priced and around 40 gigs (give or take a few). I'm wondering what people think the better brands are for this type of applications, and if possible, a suggestion on a model. Thanks Exabyte VXA-2 fits your bill. Pricewatch lists them for just under $800. You can then use X10 tapes for 35GB native, and once you need them, use X23 tapes to get 80GB native. Rob |

Affordable to me is $200. and that's why I am now looking at external HDD. OP was asking for a tape option (See subject: Tape Backup). VXA-2 is as affordable as it gets for a reliable tape drive in the capacity range he asked for. $800 is a lot of money and you'll need to invest another $150 in a set of tapes, but that buys you a lot of protection. HDD backup isn't bad for casual safety copies of your data, but it isn't backup. For real backup you will want to go back a number of versions ("whoops, that file got corrupted two weeks ago.."), and you want to store at least one copy off-site. If it's just your personal MP3 collection, then HDD is fine. If you want multiple versions of your backup then you may have to get multiple drives. That's $200 plus another $200, plus maybe another $200.... If you get hit by a virus while you backup drive is attached, poof goes your backup. If you drop your harddisk, poof goes your backup. If your house gets hit by a lightning strike, poof goes your backup. And one arguement often overlooked, an external HDD attracts a lot of unwanted attention from uninvited guests, poof goes your backup. Tapes on the other hand are 'dull', unattractive and will rarely be stolen by a casual thieve. If it's your tax administration, your current consultancy projects, your source code, your thesis, your latest novel or your entire customer administration then a tape drive and a decent backup strategy is money well spent. If $800 is too much, then maybe a VXA-1 will do, or you can try to find a deal at eBay. Rob |

That's $200 plus another $200, plus maybe another $200.... Well, $200 gets you around 300 GB of hard disc space. VXA2 X23 tape is $85/80GB so to back up the same amount of data on tape, you spend over $300 just on the blank tape. If you get hit by a virus while you backup drive is attached, poof goes your backup. If you drop your harddisk, poof goes your backup. If your house gets hit by a lightning strike, poof goes your backup. True, and just leaving HD's sitting around long enough often results in them failing when you spin them up again. And one arguement often overlooked, an external HDD attracts a lot of unwanted attention from uninvited guests, poof goes your backup. Tapes on the other hand are 'dull', unattractive and will rarely be stolen by a casual thieve. Also a good point--keep them hidden away or locked up. If $800 is too much, then maybe a VXA-1 will do, or you can try to find a deal at eBay. Here's a new LTO-1 for $625: http://cgi.ebay.com/ws/eBayISAPI.dll...tem=5156973017 If it's your tax administration, your current consultancy projects, your source code, your thesis, your latest novel or your entire customer administration then a tape drive and a decent backup strategy is money well spent. If $800 is too much, then maybe a VXA-1 will do, or you can try to find a deal at eBay. I don't know about customer administration but the other examples sound like such small amounts of data that you might just encrypt them and upload them to your ISP. |

For real backup you will want to go back a number of versions ("whoops, that file got corrupted two weeks ago.."), and you want to store at least one copy off-site.

That's $200 plus another $200, plus maybe another $200.... $200 gets you a 300 gig drive. 40 gig drives go for about 50 bucks, a little less than a V17 tape. If you get hit by a virus while you backup drive is attached, poof goes your backup. And how is copying infected files to a tape superior to copying them to a disk? If you drop your harddisk, poof goes your backup. If you drop it hard enough in its shock-mounted caddy to exceed 350 g acceleration then "poof" goes that day's backup. If you leave the tape on top of your car and drive off poof there goes your backup too. If you can't afford to lose one day's backup to damaged media then you need to pursue a parallel backup strategy. If your house gets hit by a lightning strike, poof goes your backup. And there is something magic about tape that makes it immune to the intense magnetic fields that go with a lightning strike? How is it that a disk, with its much higher coercivity and its metal shell all around the media manages to get damaged while a tape survives? This is one reason you retain an off-site backup. And one arguement often overlooked, an external HDD attracts a lot of unwanted attention from uninvited guests, poof goes your backup. Tapes on the other hand are 'dull', unattractive and will rarely be stolen by a casual thieve. So? This is another reason you maintain an off-site backup. In any case, a disk in a caddy generally doesn't look too sexy either. If it's your tax administration, your current consultancy projects, your source code, your thesis, your latest novel or your entire customer administration then a tape drive and a decent backup strategy is money well spent. If $800 is too much, then maybe a VXA-1 will do, or you can try to find a deal at eBay. So who is better off, the guy with an 800 buck tape drive and one tape, or the guy with 16 disks in caddys that he's running a two-week rotation backup on? You seem to be assuming that someone performing disk-based backup will only spend 40 bucks for one disk but will spend over a thousand for a tape drive and tapes. That's not the alternative, the altnernative is to use a bunch of 50 buck tapes and an 800 buck drive or use a bunch of 50 buck disks that don't need a separate drive.

I think the idea is that you could have an uninfected backup drive attached to your PC when the virus runs, the virus can wipe out the backup drive even though you weren't doing a backup at the time. The solution is if you're backing up to HD's, use removable HD's and make sure they're actually removed except when a backup is in progress. If your house gets hit by a lightning strike, poof goes your backup. And there is something magic about tape that makes it immune to the intense magnetic fields that go with a lightning strike? How is it that a disk, with its much higher coercivity and its metal shell all around the media manages to get damaged while a tape survives? The magnetic files aren't THAT strong. Neither the disk platters nor the tape gets erased. The lightning fries the drive electronics (disk or tape), not the media. With a disk, once the electronics are fried, you can't read the platters any more, without some ultra-expensive data recovery attempt that isn't successful all that often. With tape, you just put the tape into another drive and read it normally. You seem to be assuming that someone performing disk-based backup will only spend 40 bucks for one disk but will spend over a thousand for a tape drive and tapes. That's not the alternative, the altnernative is to use a bunch of 50 buck tapes and an 800 buck drive or use a bunch of 50 buck disks that don't need a separate drive. I dunno about 50 buck discs, I think you have to spend a bit more if you want external enclosures. If you just mean those pull-out caddy type discs, you have to power down your PC when you install or remove one of those things, which makes backup considerably less convenient. Tape really does seem to be superior for backup, and VXA drives are pretty good technology. Their main drawback is that the tapes are so expensive. Right now I back up to HD, but am looking towards LTO. LTO-3 has just started shipping (400 GB native!) and perhaps as a result, there's been quite a drop in the cost of LTO-{1,2} drives and media over the past few months. |
