Alternative to MO?

Hello,

I am looking for alternative to 5.2GB magneto-optical device. Now i have SONY RMO-S551, that recently began acting up - it does not accept 2.6 GB and 5.2 GB disks (only 2.3 GB are fine. yet.).
MO are used for backup (~15 GB each week). Weekly backups are now written to DVD-R. THE problem is some data, that must be stored offline (in case anything goes wrong with online copy). It is modified/updated every second day and users need easily find what they need (it is ArcGIS databases). MO disks were suitable for that task. Now, when third device is failing (we had 2.6 GB Pinnacle Vertex - dead, 2.6GB SONY RMO-S594 - only reads 2.3GB disks) and new one costs more than 2000 Euro (HP 9.1GB, Maxoptix 5.2GB), MO no longer seems acceptable.

* CD-R/RW - too small
* 5.25" MO - new device is expensive and *rare*. No local shops have any, though i can order several models. BTW, it also looks like 5.25" MO are abandoned.
* DVD+-R/RW - in case data will be written the same rate as now, it would mean 2-3 new sessions each week. Ineffective use of space.
* tape. Right now we have several Exabyte Eliant820 (helical scan, up to 7GB) devices. They were good several years ago, but right now we have a lot of tapes and a lot of problems reading them :) Really 'write once, read maybe'... Also, it is quite difficult to search for specific file in the tape (and in our case, there are hundreds of databases and millions of files).
* USB HDD? They seem attractive now, but how about reliability?
* anything i have missed?

iomega devices are not popular here. At local retailers i was able only to find iomega zip drive (250MB, lpt). Nobody has heard about Rev or disks for it :) Another possible problem - how long Rev will (might) be produced? Since nobody else will have similar hardware, it can be disaster when original equipment breaks/wears. Also that means, that at least 2 devices must be purchased ($400-500 each, almost 1/3 of new MO price).

Portable USB2 HDD still looks like best choice right now (there is about 80 GB of data), but maybe i am wrong? Firewire changes only interface.

We have several Rev drives in use, without problems.
If nobody has heard about them, then they are not up to date; Iomega is a BIG company, selling over the whole world. This answers most questions about reliability, continued service etc. I do not know wher you live, but it is a well known brand. Looking  around on the internet can learn you more. Also look on the site i gave you for more info, they have all kinds of drives, external HDDs and such also

Efficient way to get backups off site to Azure

I am in Europe (Lithuania). IOMEGA brand is known here, but not very popular. Also, it looks like there is no authorized IOMEGA service center here (maybe it is not important, but i have bad bad bad experience with Sony techsupport).

Sony RMO-S551 has 5 Mb/s data transfer rate. IMHO USB2 speed will not be worse :)

The usb 2 speed is up to 480 Mbps, while firewire = 400Mbps
BUT you must have a motherboard supporting USB 2, And the external HDD of course also.
Or you must use a PCI adaptor, and then the choice is yours.

This list claims they ship to lithuania :

Maybe REV isn't that popular yet because it is still new technology. I myself would probably go for a REV as it is uncomplicated to use, it comes with different connection possibilities (ide, usb, firewire), you get external and internal models, the price isn't that high (Much lower than a tape backup system), there's enough capacity (you are comparing the price with MO, but there the media only has around 5Gigs).

You are comparing tech. support with that of sony. I would probably agree there, as sony is more used to making consumer products which generaly you bring back to the retailer you bought it from, and not directly to sony. Iomega would probably be closer to the customer as their products are specialized in storage for PCs.

And, up to now, and speaking for myself, their support is very good : we had from a former product a bad power supply, they shipped us a new one, without even asking to retorn the bad one.

If you want cheap media, a big load of cassettes and toss them in the trash couple of years later, then go for dvd-ram (evil grin ;-)

If you want professional longer-term stability :

(1) if you need direct file access, i would go for external harddrives. A 250G external disk is cheap these days. Today Maxtor has a top drive with the OneTouch II. (http://www.maxtor.com/portal/site/Maxtor/)

(2) if you need it for backup or archival purposes (no immediat file access) i would go for a tape drive. have a look at the DLT, LTO or AIT tape-drives.  We use LTO2, they aren't cheap but i can assure you a file is back in less than a minute.

hope this helps.

Just to back up what Lieven Embrechts said, I have used Seagate (used to be Quantum) DLT drives for backing up over 120 GB per day, and have only had one error in 3 years. Have burnt out one drive, but it is used in an extreme setting, so is understandable. The library consists of over 200 - 70 GB tapes, with 3 drives running and it has proven to be very cost effective for that amount of data. You may want to look at that, as 40GB tapes and the drive arent that expensive, and with your "relatively low" backup rate, it would be a good fit.

The way I understand tapkep, a tape-type backup isn't what he is looking for in this case, otherwise the DVD+RW system would work OK. It seems more like he needs easy copying with the possibillity to add data to media already copied to at any time. That needs some disk-type backup system.

Thank you for responses :)

rindi is right, tape is not suitable solution in my case. I need ability to update/retrieve data easily, (without rewriting all the tape).
Cyber-Dude, your provided links are interesting, but i am afraid, that shipping might be a bit complicated... I am not in USA :) As for second link -   >B-]

Right now i have (finally!) found european Sony storage techsupport. Maybe they will have any idea.

For new device - IOMEGA Rev looks nice, but probably i will end up with portable USB/IEEE1394 HDD. BTW, portable HDDs *can* be plugged/unplugged any time? :) (need to be sure, because reviews does not mention that obvious (?) thing.

All the USB devices can be unplugged at any time, provided you use the "remove device safely" icon in the system tray

Actually, with a DLT and Backup Exec, it isnt a linear backup. You can overwrite data (although overwrite may not be the correct term here). Veritas has Backup Exec (which we use) and we have to overwrite job folders with updates constantly. Is a very fast system actually. Just a suggestion though from someone who has it and found it works well.

Generally I'd say USB Harddisks should work fine. Sometimes you might have some power problems, so make sure you get something you can connect to an external Powersupply.

Thanks again for your opinions :)  Last week i bought Maxtor OneTouch 80GB USB HDD. With regular dumps to DVD-R, (i hope) everything will be fine.
