Multi-tape backup with dump
I've been backing up a filesystem with dump -0auL -b 60 -C 32 -f /dev/sa0 /share on an amd64 box to a 100G LTO drive (dmesg below). It works fine (*) as long as the filesystem fits on one tape. However, dump wedges when I put in a new tape. When I check with top, typically two dump processes chew up as much cpu as they can, sometimes only one and sometimes all three. DUMP: 59.07% done, finished in 1:16 at Mon Oct 17 13:32:53 2005 DUMP: End of tape detected DUMP: Closing /dev/sa0 DUMP: Change Volumes: Mount volume #2 DUMP: Is the new volume mounted and ready to go?: (yes or no) yes DUMP: Volume 2 begins with blocks from inode 10477547 It will sit like that indefinitely. The tape doesn't move (I can't hear it and mt says the same thing). mt -f /dev/sa0.ctl status at this point: Mode Density Blocksize bpi Compression Current: 0x40 variable 00x1 -available modes- 0:0x40 variable 00x1 1:0x40 variable 00x1 2:0x40 variable 00x1 3:0x40 variable 00x1 - Current Driver State: at rest. - File Number: 0 Record Number: 1Residual Count 0 If I do a ctrl-c, dump stops chewing up the cpu and politely asks me if I want to abort the dump. Is there some trick to doing multi-tape backups? It doesn't seem to matter if I use the button on the tape drive or mt offline to swap out the tape (I should hope it doesn't matter). I've tried generic kernels built locally, GENERIC from snapshots, and (for the particular dmesg below) a custom kernel. No difference... Given that it takes a few hours to fill a tape, mucking with this is a bit tedious. The most interesting thing I've found is that setting the tape size explicitly *does* work (although I've only tried forcing small tape sizes). The system I have now is from a make buildworld/make buildkernel from yesterday, but I've never had a multi-tape backup work (going back many months of tracking -current). Until now, it has always been faster to clean up some files and do the backup again rather than reading through things carefully to see what I've been doing wrong. Until now, anwyay, and I'm not finding anything in the docs. Anybody have any ideas? I hope I'm just missing something stupid somewhere...? Thanks.

We have a few different levels of DAT DDS-2, DDS-3 and DDS-4 as well as DLT and LTO drives in various systems - all on SCSI. Dell sells DLT and DAT. HP is pushing LTO (they call Ultrium). The DLT and LTO performance are all outstanding. If you do frequent backups (recommended) I would steer away from the DAT (DDS...) because they really can't handle the heavier usage. Reliability becomes a problem over time. On some other systems we also have AIT drives working well but I haven't used them on FreeBSD yet. Unfortunately the DLT and LTO drives are rather expensive. But the high speed and reliability will be worth it in the long run. As for software, we just use dump(8)/restore(8). jerry Thanks for any insight. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

tape backup coredump
Good morning all. I am having a problem with my tape drive, which gives me a coredump when I try to bsdtar any directory. The gtar doesn't, however it exits with an error message.

Travan 3 Parallel Tape Backup in FreeBSD 4.10
Hi, I'm trying to install an Imation Travan 3 parallel tape backup in a FreeBSD 4.10 box. Has FreeBSD support for it? I tried several things, including using the mt command with /dev/ppi0: # mt -f /dev/ppi0 status mt: Inappropriate ioctl for device And i don't know what that could mean. Any idea? I've been looking in the freebsd site, and the web, but I couldn't find any references to using this devices (only found a couple messages from mailing lists 8 years old asking if there was support for this kind of thing).

Tape backup solution? [OT]
Hello List, I have a question that's slightly off-topic, but not. I install high-end surveillance equipment for CCTV and such. I have a rather large client in Minneapolis who's using Dedicated Micros digital video recorders. The particular model we're using has a 500 GB hdd, but this client would like to archive images to tape for longer storage. As of now, we're only getting about 2 months of recording time. For off-site viewing, this unit can off-load images to a SCSI cd recorder. Does anyone suggest a tape backup device that would be SCSI and external, with a fairly high-capacity? I'm thinking around 50 GB?

Re: newbie: weekly tape backup advice
Hi, I need some help setting up a tape backup system. I have two FreeBSD machines and on external SCSI Onstream ADR50. Got any clues how I can start a weekly back up plan here? It depends a little on the size of your disk compared to your tape capacity. It also depends on how much - amount and frequency - critical data changes. If you can fit everything you want to back up on one tape, just run a full backup (level 0 dump) each time being once per day or once per week or whatever fits your data change pattern. If your critical data change is a lot and a full backup of it will take more than one tape, pick a convenient day of the week and do a full back up and then do incremental backups (level 1 dump) other days. If your disk is so big and the amount of change so much that a week's worth of incremental backup needs more than one tape, then you will want to do a weekly full backup and then increasing levels of incremental back up (level 1 - 6) on the other days. If your amount of data change is quite low - say it is just hosting a fairly static web site and some information database you look at but don't update very often, you might want to consider doing only a weekly full backup or a monthly full backup and weekly incremental backups. Use enough tapes so you are keeping at least three copies of each part of the rotation before reusing a tape. You may also want to do a quarterly or annual archive dump that you store off site and do not reuse for several rotations. For sure, you want to use dump(8). It is part of the system, does the right things with the files and is reliable and doesn't take any tinkering. Unless you have a lot of very critical files open and being changed all the time, don't bother with the warnings about doing a dump on a non-running system. The dump will work just fine.It only means that some file may change between the time the dump started and when it finishes so that file's backup image might not be good. But, if you are doing regular backups -_and not just reusing the same tape all the time_- you will catch that file in a good backup on another day. The man page explains dump pretty well. Mostly you shouldn't need to worry about block size and all the other special stuff. The defaults work best for most circumstances. Determining the media capacity may be the only difficult thing. If one tape will hold the entire backup, just use the '-a' switch. That can work well also for multiple tape dumps with tape drives that give a good end-of-media indication. But some of them - DDS can be an annoying example - tend to not work well when getting near the end of media and will start getting write/read errors before the end-of-media indication actually happens. Then, the system may not handle things very well and you may want to do some calculating and experimenting with either the '-B nnn' parameter or the '-d nnn' and '-s nnn' parameters to specify a media size and force it to change tapes before the problem area is reached. You need to run dump(8) as root. Eventually you will want to not have to retype the dump commands each time or you will want it to run by cron at some time you are not around, so either make a script and run it while su-ed or logged in as root, or make a compiled program that will do the dump calls and make it suid root and then make it owned by root with a group of the only ids that will be allowed to run it and then give it only 750 permissions. One more thing from experience - do not run the head cleaner cartridge any more often than you absolutely have to. In a very clean environment that can actually mean never. But, you will probably need it now and then. Experience will tell when. Those cleaners cause significant wear on the heads and possibly the rest of the mechanism. It doesn't take much to wear those tiny heads down to nothing. So, using them as infrequently as possible will actually help increase head life, not reduce it as some of the accompanying printed material often likes to imply. I think they just way to sell more replacement tape drives. jerry Thanks in advance, Noah ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

No, you don't do sth. wrong. Onstream did but didn't tell it it's customers before the buy. The produced streamers with an SCSI interface but didn't respect the SCSI streaming access commands, but implement an own command set. You can do some things to get it work: 1) Port the linux driver to FreeBSD 2) Use vmware to run either linux or windows which may grant access 3) Use another streamer 4) Use another backup medium. just like cdr Jens ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Tape Backup Failure Following Reinstallation of 4.7
Just installed/upgraded to 4.7-RELEASE. I tried to restore some 4.5 config files from my tape system and received a message, Device not configured. The tape cartridge had not been inserted so I pushed it in and tried again. This time the message read, Input/Output error. I'm a newbie so I was surprised since the tape system worked under 4.5 and it worked following an earlier binary upgrade to 4.7. I noticed that the SCSI controller was sharing irq 11 with the graphics card. Could that be the problem? If so, I can make that adjustment when I install a new Nvidia card. Also found that the kernel lists the SCSI controller device as adv0 at isa? This isn't the way it appears when I run dmesg. Any advice would be appreciated.

We have a couple of systems that cannot be written/read with dd or cp which causes us a problem and we haven't discovered a reason yet. Those are all on Dell systems, but I don't remember the drive model[s]/maker[s] at the moment. Interestingly enough, tar will still write/read them.

RE: Tape Backup
I've never ran one on FreeBSD, but I've used several DDS-3 drives of all kinds of flavors. I've had some problems with some Seagate ones, but aside from that, I've had no problems. The only thing I'd keep in mind, and that I've experienced is that the DDS-3 tapes are not designed for heavy use. From what I've done, using 5 tapes a week, one a day, I end up throwing the tapes out (after destroying them) after about 4-6 months...which is fairly average from what I've heard. Also, a cleaning tape, though I never believed it till I saw used it, increased the life of the tapes slightly, and I assume it also extends the life of the drive...but I've never seen one croak, so I don't know.

I've never ran one on FreeBSD, but I've used several DDS-3 drives of all kinds of flavors. I've had some problems with some Seagate ones, but aside from that, I've had no problems. The only thing I'd keep in mind, and that I've experienced is that the DDS-3 tapes are not designed for heavy use. From what I've done, using 5 tapes a week, one a day, I end up throwing the tapes out (after destroying them) after about 4-6 months...which is fairly average from what I've heard. Also, a cleaning tape, though I never believed it till I saw used it, increased the life of the tapes slightly, and I assume it also extends the life of the drive...but I've never seen one croak, so I don't know. Your experience sounds about like ours. I think we get just a little more average life out of a cassette than you indicate, but not a large amount. Actually, we've used some DDS-4 too with pretty much similar results. One thing though, the cleaning tape may increase the life of tapes, but frequent use can reduce the life of a drive. The cleaning tapes can cause increased head wear. We recommend only using them when really needed - write errors show up - and not on a regularly scheduled basis. But, this is true of DDS-2 and even original DAT. Keeping your drive and storage environment clean and as free of dust as possible is a more important thing to improve tape and drive longevity, I think. If your usage justifies the cost, you might want to consider DLT or LTO type drives. They handle the load with less failure and higher capacity and data rates. jerry Hope I helped, --Brian -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Peter Erickson Sent: Saturday, December 14, 2002 7:57 PM To: [EMAIL PROTECTED] Subject: Tape Backup I am running Freebsd 4.6 and my dds-2 tape backup drive just died on me.
