we are trying to decide on a new backup technology. right now we use AIT-1. But we want to go to D2D2T.
Any suggestions?

I'd go for LTO. You have more capacity. With AIT your at the mercy of sony, and my experiance with sony's IT products, mainly if you need some customer support, has not been something worth any recommendation at all.

My vote is for LTO over AIT also. From what I have seen in the field LTO tapes are more reliable that AIT.

Speaking from experience, we use a LOT of lto's for backups.    They're relatively fast, and very reliable.   The capacity is also great.      LTO to me seems to be one of the hot 'standards' for backing up, similar to DLT tapes a few years back.

Do you mean you use a LTO of LOT's?

We have customers using both.

AIT-1 drives attract quite a few users coz they're quite cheap (compared to LTO) and you can get a firewire/usb external one, which is great for hot-swapping and redundancy. That said, we havn't had one go wrong yet, which is good for tape drives, which still have Lots of Moving Parts.

You can also get ain internal IDE (ATAP) AIT-1 drive which is useful as a budget option BUT be aware that the default Sony drivers do NOT allow you to change the block and buffer sizes and count, and the default settings are not right, which leads to shoe-shining and backups taking about twice as long as they should do given the native speed of the drive. :-(

LTO drives are faster, bigger, but more expensive to buy, and require a SCSI controller card. If you can afford an LTO drive, go for it, and I would also recommend an external unit again for easy swap-out in the event it fails. We have sold Seagate and HP LTO drives and they all work fine - we *have* had drive failures of the Seagate in one client but the client has a VERY dusty environment and the dust is sticky and Seagate swapped it out under warranty on a "next-day" delivery, no hassle.

Frankly, if you have the budget for it, go LTO every time.

Don't overlook tape cost when budgeting - both AIT and LTO tapes are quite expensive compared earlier systems.

If you compare the tape price along with the capacity, LTO's are cheaper than AIT's (AIT's also have a builtin chip and electronic contacts, which may be the reason for the higher price), and both are probably also cheaper than DDS type tapes. You should also compare the life time when comparing the price. DDS don't usually last long.

Well, right now we are using a Qualstar Library with AIT tapes.  It has been working great but now we are backing up alot more data and I want to get a soultion that will let us grow.  It looks like LTO may be the way to go.  If not just for the capacity on a single LTO3 tape for the speed as well.

All good answers, I don't know who to give the points to.
