Linear Tape File System
on Mar 2, 2011 at 7:12:05 pm

Does anybody use it? Or the HP LTFS? The Wiki article says they've been developed for OSX 10.5:

http://en.wikipedia.org/wiki/Linear_Tape_File_System#Supported_operating_sy...

I wouldn't mind giving BRU PE the boot, if this is a viable alternative. Can anybody share insight?

If I switch, I'd need several days to copy all my LTO tapes to RAID using BRU PE, before copying them back to LTO using LTFS. So, it'd be nice to know whether it would be worth the trouble.

If I understand it correctly, one would be able to mount an LTO tape and have it appear to be a drive, and use the Finder for copying and restoring, and wouldn't need the special GUI that BRU PE and Retrospect use. Right?

Jim,

Check these folks out. http://storagedna.com/


They're one of the first companies to bring LTFS to market.

Storage DNA's product - DNA Evolution - Excellent product, and some really smart guys at the helm. They utilize their DNASync software to move & delta sync the data from HDD to Tape (LTO5 is fast), as LTFS at the OS/Finder level is somewhat wonky - LTFS is still pretty new.

(full disclosure, the company I work for sells the product)

Hi Mark and Michael,

Thanks for the heads up about DNA Evolution. I browsed the site, and I have to admit that all the gobbledy-gook makes my head swim. I'm not an IT expert, just a Sole-Proprietor video Editor who needs to archive terabytes of footage. Michael, if you want to entice customers like me, you need a separate dumbed down page, IMO, that speaks to prospects who don't know the lingo.

I may have jumped the gun on my OP. I have since learned that LTFS only works on firmware enabled LTO5 drives. IOW, it's not likely to be supported on LTO4, which I own. I guess it's possible that Quantum will make a firmware update available, but that's just dreaming out loud.

Notwithstanding that, further reading - and I haven't been able to find very much - seems to support your conclusion, Michael, that it's "wonky."

I've learned also that Quantum and HP sell LTFS-capable LTO5 drives, and offer free software for OSX. What I still have yet to learn is how people in my business, at my skill level with IT stuff are getting along with it.

I'm not scared at the prospect of buying a new LTO5 drive, but the hardware isn't the bugaboo. I've encountered issues with Retrospect and Tolis, and not sure open-source is a solution either. But, the notion of simple Finder-like interaction with a virtual mounted disk is appealing.

So, I'd still love to hear from some users about it, if there are any.

Hey Jim-

Thanks for the feedback - I'd be more than happy to pass along the suggestions to StorageDNA.

Yes, HP and IBM both make drives, and both are pretty good.

LTFS is a fantastic approach to bridge the gap from spinning disk to tape (we've kinda gone full circle, eh?). Since it's still in it's infancy, there are some stumbling blocks and learning curves. Simple drag and drop OS operations (as well as other basic needs, like spanning across tapes) still have a few hiccups, which is where 3rd party software comes into play (ala DNA Evolution) to help remedy those issues.

If you're looking to something dead simple and very robust, you may want to look into Cache-A. It's LTO5, and while not LTFS, it does present itself as a shared network volume that you an drag and drop files to and from, as well as having a web page based catalog and administration panel. Best part, is that all media is not saved as a TAR format, which makes searching and restoring individual files easy. It does run between 8K and 12K, however.

Hi Michael,

Yes, I've read superlative things here on the CC about Cache-A. But, that price is a talk-to-the-hand for my two-bit operation.

Most of my peers are getting by with a stack of drives for backup. I'm getting by with BRU PE 210 and a drive they stopped supporting after I'd already bought their software. That makes me nervous, but so far, it's working, with a simple interface, and I plan on sticking with it until one of my components breaks or becomes obsolete by a future upgrade.

And with Lion and FCS6 supposedly around the corner, that could be sooner rather than later. Hence, my curiosity about the next greatest thing.

Thanks again,
Jim

I too am a small shop. My perpetually limited capital budget has always been spent on everything but an archival tool. That changed late last week with my purchase of the Storage DNA Evolution with auto-loader. It will be a while before I know whether I chose the right vendor but I'm convinced I made the right decision moving from spinning drives, DVD and head-in-the-sand hopes to LTO.

I think Cache-A makes great products with a proven track record. BRU has been in the business a long while as well. Once I read deeper into the Storage DNA story, I came to believe they're offering a solution driven be people who intimately understand my business and work flow.

The boxes arrive next week. Soon afterward, I intend to sleep peacefully, for a change. The Storage DNA acquisition was driven by my recent loss of two near-completion projects due to a storage failure.

Hopefully, sometime in June, I will have implemented a vault solution that will end decades of concern about asset management. We shall see.

Hey Les,

I am sole proprietor investigating StorageDNA as well and curious as to how their solution has been working for you.

Please post any pros / cons if you can as it would be great to hear from real world users like yourself vs. marketing materials.

Thanks in advance for any info you can share on your setup.

Best,
Gardiner

I'd like to thank Michael for the mention, but wanted to correct a misstatement on his part.

[Michael Kammes] "If you're looking to something dead simple and very robust, you may want to look into Cache-A. It's LTO5, and while not LTFS,..."

Cache-A most assuredly is LTFS. While we introduced our products with tar archiving before LTFS was available, we were one of the first adopters with a technology showing at NAB2009 and shipping LTFS by NAB2010. Users can choose tar or LTFS format on a tape-by-tape basis and take it to the next level with our cataloging and extended metadata support. We'll even be showing support for the new Discovery Channel LFTS requirements at NAB2013.

And, while I'm at it, I'd like to correct another misperception that many share with Jim:

[Jim Curtis] "If I understand it correctly, one would be able to mount an LTO tape and have it appear to be a drive, and use the Finder for copying and restoring"

While this statement is true in the strictest sense, those that try this with the free software from IBM or HP, run into serious problems due to the linear nature of tape. When you try to restore many files from an LTFS volume, if you don't ask for items in the order that they were written to tape, it can literally take days to get all your files back. Products like Cache-A and SDNA presort restore requests among other things to make using LTFS truly practical.

The costs of these products are well below what editors used to pay for video tape decks which is how they used to archive content. I invite readers to check out our white papers for more information about the advantages of using complete solutions rather than attempting to roll your own.

Thanks for the info Tom.

As I'm sure you can understand, the LTFS implementation around the time of the post was still very new and somewhat enigmatic. I don't believe we had sold any LTFS enabled units at that point.

Press release from 1/2011:

http://cache-a.com/canews/Cache-A_HP_LTFS_012511FNL.pdf

As resellers we were, of course, thrilled - LTFS holds much promise.

Fast forward 2 years, and I'm very pleased to see LTFS continues to find for play in the media realm!
