Only in places that need vast amounts of data stored for a very long time with restores being rare. Restoration is slow with tapes. Even a low end LTO drive will set you back thousands of £/$/€. Most consumers and even most businesses will find it more cost effective and flexible to backup to HDDs and storage clouds. Cheers, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting

New tape drives are expensive because they are only sold to businesses; used tape drives are cheap because no business wants to buy them. That said, even a new tape drive is a finicky beast compared to a spinning disk; anyone operating them should really have a spare drive, tested, sitting around and waiting for the primary one to fail. -dsr-

Yes. However, my company has switched over to using disk storage for backups. The time-cost for retrieving a file or a directory is much lower, and we do that small recovery much more often than we need to bring back an entire machine. Also note that LTO-2 is 200GB per tape, not 600. Tape manufacturers have an awful habit of pretending that all data is compressible, and citing a compressed storage amount instead of the raw storage amount. https://en.wikipedia.org/wiki/Linear_Tape-Open should be helpful to you. -dsr-

Depends on the context you're talking about. I am given to understand that people do very much still use tape drives for backup in a server-room / data-center type of context. However, while I've considered using tapes for backup in my own private environment, last time I looked the cheapest tape drive with support for tapes large enough to be reasonable for my hard-drive capacities was $3000 - and that's just the drive, not the tapes. That rivals - and may surpass - the build-from-parts cost of my entire computer, which is already nearly half storage by dollars spent.

[OT] LTO-1 tape drives
Hi all, I'll be setting up my Tyan P-133 box as the secure /home data repository for our home use. I need a backup solution that allows me to take it with me (not just copy it to another computer). Backup set size, tarballed and encrypted with openssl, is around 50 GB or so. I considered using a laptop drive in a mini-enclosure but the Tyan doesn't have USB (and I'd rather not add USB to this box). I don't want to use a 3.5" drive since, in an enclosure, it won't fit in a small bank safety deposit box. By the time I buy, e.g. three drives and enclosures, price starts to get up. I'm thinking about LTO-1 tape drive. The LTO-1 has a slow enough transfer rate that the EIDE hard drive should be able to keep it fed. However, new drives are pricy. What about eBay? There is an eBay store physically located (and allows pickup) an hour's drive away that has LTO-1 drives for under $100 or so and come with a 30-day warranty. Assuming that they also have the appropriate SCSI HBA for PCI, that plus a new set of tapes should do it. Does anyone have any experience purchasing used tape drives? Is there any way to determine during the 30-day warranty period how long the drive will last? Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

The tapes, tape drives and SCSI cables are all known good, as they were recently retired from working HP-UX systems. To date, have destroyed 3 tape drives and 10 tapes trying to get any tape media command to talk to them; i.e. tar, cpio, mt, btape, dd All fail, see original post for gory details. The end result is to wrap the tape around the capstan to a degree as to destroy the tape and eventually destroy the tape handling mechanisms of the tape drive itself. I actually opened the cover of the mechanism to watch what was going on on one of the tape drives. It appears the tape tensioning sub-routines are not being called correctly. I say this because, the tape is loaded fine and the tensioners correctly pick up the tape from the cartridge, wrap it around the helical scan head; all OK. But during tape movement or eject, the tape tensioners relax and the tape is so loose as to cause it to wrap up on any moving part, like the capstan and helical scan head. When lucky, and no tape wrap-up occurs, the other problem is that since the tape is not tight around the head, no data is successfully read or written. I/O error is the result. As indicated I have cleaned the tape drives, changed cables, changed tapes changed drives all yield the same results. My guess here is that something changed in etch, in the SCSI tape routines so as to cause this; only a guess. Curious part here though is I have a HP SureStore 12000e autochanger connected to the same SCSI bus. The 12000e also uses a DDS2 tape mechanism. The 12000e has worked flawlessly through the years as my Bacula library. My idea for the C1533A was for tar, cpio, or overwriting Bacula tape labels when it's time to recycle tapes. Since the 12000e is a 6 tape library with a autochanger robot, it has its own device file for the autochanger robot, whereas the C1533A does not. The only saving grace here is that the C1533A tape drives and DDS2 tapes are no longer being used in production, therefore they would have gone to the scrap heap if I hadn't snagged them. Never thought it would be this hard to write a tar file to a SCSI tape drive. Been using K3B and dvd's until I can get this figured out.

I recently had what I thought was a drive failure. It was 2 tapes failing at once as required by Murphy's Law. Probably none of the original tapes remain. Somewhere I saw quoted that the expected lifetime of these tapes is 20 read/write cycles. I am running them long beyond that. It is probably reasonable to figure on replacing 3-5 tapes per year. Note: 3 tapes == $100-$120. Tape drive $200-$290. Alternatives are going to cost more up front. Hopefully, cheaper media and longer life will more than make up for it.

Your basic method listed in the rest of the email is the way to do it. Keep in mind this tape drive will self destruct in about a year or two of use. Sometimes silently. At least you're using a Seagate and not an HP, which will last 6-12 months if you're lucky. As for other IDE drives, I don't know of any offhand that are worth the time.

I don't see why the IDE version wouldn't work...essentially it is the same drive so if the IDE portions of it work then...like I said...a great drive just a week or two ago I did a complete backup, repartitioned my drive (backup being tar cf /dev/st0 / /home -l ) and then booted off a floppy and restored (after repartitioning, reformatting) and it worked great. like I said thoI dunno about IDE... the only thing about IDE is I kno wit doesn't recommend (manual was the same for both version BTW) putting it on the same IDE controller as the hard drive if you can afford it (remember I said I paid $209 for a SCSI version of the same drive at www.compuplus.com) I would go SCSI , but if you have a free IDE controller (I think it doesn't mind too much going on the same one as a CD ROM drive) then the IDE SHOULD work I was advised before I was even looking at tape drives "You can use any scsi drive and most IDE drives" -Steve > Thanks, > > Brian > > -- > To UNSUBSCRIBE, email to [EMAIL PROTECTED] > with a subject of "unsubscribe".

ATAPI Tape Drives
Can anybody give me any con's of the Seagate Tapestor 8G IDE tape drive? I found a great deal on one and want to look out for any gotcha's. I checked the Hardware compatibility list and it is on there but I thought I would just check. The ide-tape.c driver says it is still alpha. How stable/unstable is it?

It will probably work, but I would suspect that the throughput will not be all that great. I would bet that you'd be sorry if you tried to put a hard drive on that controller. You'd never get full throughput out of a modern SCSI drive. For just a tape drive you might be okay, though. Some SCSI card that come with scanners are absolute junk, though (no IRQ line) and shoud be avoided like the plague. It's also sometimes useful to put slower equipment on one SCSI bus and faster equipment on another one. If money's an issue, maybe you can just use the Zip card for a while and then add a better card later. > I am looking for any recommendations (I am tired of buying hardware and > having it break and not work so easilyso this time im not going to > "Impulse Buy" my computer hardware) NCR-based cards are cheap (~$50 for an NcR53c810) and well-supported. Buslogic and (I think) Advansys actively support Linux and make good cards. Adaptec does not support Linux and the drivers have to be reverse-engineered, but usually work. The SCSI-HOWTO has some good information about this. Sincerely, Ray Ingles (248) 377-7735 [EMAIL PROTECTED] Two rules for success in life: 1.

A travan TR4 tape goes for about $24 minimum. In contrast a 4mm/90m DAT tape costs about $4 and an 8mm/112m about the same. This may not be an issue for a home PC where you can get by with a handful of tapes, but it's something to consider. The disadvantage of 8mm and 4mm is of course that the drive prices are much higher, the cheapest 4mm running about $485. The other thing to remember is to get a couple of cleaning tapes, whatever drive you end up purchasing. As to using SCSI tape drives, I can say that my "ancient" 4mm WangDAT 6130HS, attached to an Adaptec 1542B, has worked flawlessly for about 3 years (and two computers) under Linux, and I can say that the drive has saved me a lot of heartache. It's probably the best hardware purchase I ever made. Good Luck! Gary -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Tape Drives (SCSI vrs. Parallel)
Hello again everyone, A little ways back I asked some things about Tape Drives, and I really appreciate all the responses. One last thing, though. I lot of people mentioned one with a SCSI card, but I think that I can only afford a parallel port one. Now, I know that it will be slower, but that is ok. Speed doesn't matter as much for me... My main question is about reliability. I know a SCSI is better that way, but would my backups be seriously less reliable of I use the parallel port version of the 1gig (well 2gig with compression) Iomega Ditto drive? My primary use would be for backing up program archives and datafiles (zips, movie files, pictures, etc), and probably weekly hard drive backups, so I wouldn't be using it constantly... Also, do the backup programs usually have some sort or error correction while backing up?

I have a Ditto 3200 and it works fine with Linux (compiling ftape into the kernel). I understand that there is now support for the 2 GB Ditto (and Sony) drive, but you need to get a newer version of ftape and add it to the Linux kernel.

Tape Drives?
Hello everyone, Please forgive me for a question that has probably been asked thousands of times. I've just been so busy lately that I haven't been able to do the research I usually would. Does anyone have any recommendations on a tape drive that would be compatible with Linux? My problem is I want to install Linux, but first I need to format the drive. Before I can format the drive, I need to back up everything. Unfortunately I am just out of room for backing up things. I already have a zip drive, but it has gotten to the point where much of what I am backing up is things I would only really be using as backup archives, so that continuing to buy more and more zip disks doesn't seem appropriate (especially in the wallet). I also figured that since Linux is more sensitive to things like sudden outages, a tape drive would be a good thing to have. My other problem is how much I have to spend. Around $100 is what I'd like to go for. $150 is pushing it, but should be able to manage it. I had first also considered a CD-R, since I have musical interests, but those seems to be about $300 for the cheapest models. An Iomega Ditto seems to be about the right price, and I have heard good things about it. Unfortunately I've also heard that it can't be used with Linux yet. I did find one page with a guy that seemed to have nearly everything nailed down, and the page was marked April. Has any more progress been made? Or is there another tape drive that is compatible and about the same price? I suppose that if the Ditto still isn't compatible, but people believe it will be in something like 3 months, then that'd be fine, too. It'll be a little ways before most of my stuff gets transferred to Linux... Thanks everyone!

I have tried a lot of blocksizes and reboots between them with no difference (or improvement). Give tob or afio directly a whirl (if you have time). I know I've got a sick 9 GByte disk drive (and we're going to the doctor tomorrow), and it's not clear whether or not my tape problems are related. In any case, it's awfully curious why I am not having problems with tar but do have awful problems with afio on the same (350 MByte) directory. Cheers, Susan

Here's a data point: I didn't have any problems reading my Exabyte SCSI drive with 2.0.0 last night when I upgraded my home box to 1.1.5. One thing to think about is the blocksize. If you've run "mt -f /dev/st0 setblk 0" (which is good for reading tapes written by SunOS and AIX I have found) you won't be able read tapes written with the default block size (whatever that is) and vice-versa. I haven't done any performance tests to compare the effects of different block sizes but would be interested to hear from others who have (I use tar for backups).

heads-up about SCSI tape drives
I've been having a lot of problems with my SCSI tape drive in the
past week or so ("Unrecognizable archive", etc.). Another user
also told me in private email that he'd also been having trouble with
his SCSI tape drive. (I have an Exabyte 8505; I do not know what kind of
SCSI tape drive the other user had. I do not know if these problems occur
with DATs.)
Dirk Eddelbuettel kindly suggested today that I try the new (2.0.13)
kernel. I took his advice and it worked. (Nothing new there!)
Suggestion: if you have a SCSI tape drive, you might wish to check that
you can read from it, and/or you might wish to upgrade your kernel.
