  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Quantum 600a desktop or rackmount...who has the best price?

R3d Overload here.

I have no other choice then to invest in a system that can safley back up my R3d data. Through plenty research and talking with many of you it seams that the quantum 600a SDLT tape system is the one for me at this time so now I just need to figure out where to pick one up. I am leaning towards the rack mount set up cause that is how my studio is configured although the desktop version maybe better choice for backing up in the field?

Any suggestions are much appreciated.
 
Not sure about that model, but I just purchased and set up a Quantum LTO-4 and am VERY happy with it. I thought I would be a little over my head in IT land, but it has worked pretty easily using Retrospect as my backup software.

It holds 800 Gigs per $86/tape. The write to tape is definitely slow compared to a harddrive, but bringing files back was pretty quick. I think I brought back a 100Gig file in less than 30 minutes.

At first I liked the allure of a "drag and drop" setup like LTO-3A, but the more I've used this, the more it's no big deal. The software catalogs your backup, so any time, you can see exactly what is on a given tape and bring back only 1 file if you want. This was different than I thought it would work...and I'm very happy about that.

Let me know if you have any questions on LTO-4. I have it hooked up via a SCSI SAS card to an XServe that then shares an XRaid.

Kevin, which LTO-4 drive and controller card did you go with?
 
I got a Quantum LTO-4HH desktop casing tape drive. It was less than $2,800 and included (though my rep didn't know it) the LSI SCSI SAS card for the PCIe slot of our XServe. I did need to buy a cable...

Working pretty great.

Thanks, Kevin.

Yeah, it seems that's really the only LTO-4 SAS combination that's working on OSX right now (Quantum HH + LSI card + Retrospect).
 
how long does it take to backup 320GB of data on LTO-4HH? (and full 800GB?)
is it possible to preview the files in retrospect before you decide to backup the file?
 
Same LTO4 setup here.

Full 800Gig with a verify pass takes just under 6 hours. But this is a full vfx project.. some large files.. lots of small files etc.. Suspect would be quicker with just large files.

This was coming off a Raid though on a server capable of about 200MBs.

Streaming to SAS just off a single internal may be a bottleneck. You need to feed the LTO4 drive as quick as it can write to tape or it gets a bit unhappy.

Works well..

RE: Preview.. do you mean as in view video files? or view a list of files to be backed up ?

You create a dataset to backup. This consists of folders that you have made available to Retrospect to see.

It's pretty simple really.

in quantum's website, they have some 'disclaimer' about 2:1 compression and some information about ES 256-bit data encryption. does it mean the r3d files will somehow be compressed in the tape? does the 'encryption layer' work properly with the (proprietary) R3d files?

(and, can i backup say 1.6 TB of data on a single tape with the 2:1 compression?)

Thanks folks...I was not aware Tekserve had these systems, I will head over there report my findings.

The tapes can fit 1.6TB IF the file is compressed. I've always heard that we should NOT do that with video files. I am fine with 800Gigs native, uncompressed data. That is what I've been doing, with no problems at all.
 
im also looking for an LTO solution so id love to hear your findings and if you purchase one maybe working out a deal for storage of a feature we're about to start.
PM me if you have some info.
 
Same kit is over $250 cheaper at Provantage.

FWIW, I just bit the bullet and ordered the kit along with Retrospect 6.1 Desktop for Mac and 5 blank tapes (kit comes with one). I'll let everyone know how it goes when it arrives. Just did ground shipping.. Provantage has the Quantum LTO-4 tapes for $74 each. That's about the best price I've found on tapes unless I want to buy 50+ at a time.

Thanks Jeff, this really helps me out on a couple of levels. I look forward to your findings. Thanks again.
 
That's an excellent price.

Great unit...you won't be disappointed.
 
There is no "Best for Red." These drives are as good for RED footage as they are your bank statements. It's all data.

I'm no pro at this, as I'm a video guy and this stuff is much more IT-based, but here is my summary:

LTO3 only holds 400 Gigs while LTO4 holds 800 Gigs without compression.
LTO3 is slower than LTO 4.
LTO4 is more expensive, but LTO3-A is much more expensive than either.

However, LTO3-A has a volume/directory on the tapes, so it looks like a more traditional drag and drop disk type of deal. For LTO4 usage, you must use software to first backup your files (similar to zipping, but it catalogues, checks, etc., before it moves it to tape).

I believe there is LTO-4A coming out later this year...but the "A" series for both LTO3 and the upcoming LTO4 are much more expensive. LTO3-A is 3 times that of the non-A version.

Okay, that's my info dump. Feel free to correct me if I'm wrong with any of this...
