I am looking at getting a DLT drive for my network; however, I have never used the tar command with a tape drive. What happens if the data is larger then 1 tape? Does the tar application automatically span tapes or do I need to use switches so it spans multipule tapes? Right now my Full backup will take 2 or 3 tapes.
View 3 RepliesI have been using an LTO-5 Ultrium-3000 tape drive connected to an ATTO HBA without problem. I can control the tape drive using "mt -f /dev/nst0" and have been able to make successful backups using cpio, tar, and dump/restore. I followed some instructions on the web about how to install the HPE Library and Tape Tools application (version 4.21) which relies on conversion of a rpm to a deb file. The software seems to have been installed correctly and runs. However the hardware scan function does not recognize my tape drive. The following is suggested in the user manual if the tape device is not recognized by the software under Linux:
1. Login as root.
2. Edit the following file:
vi /etc/modules.conf
3. Add the following line as appropriate:
add options scsi_mod max_scsi_luns=128
4. Reboot the computer.
The problem is I don't have an /etc/modules.conf and am not sure exactly which file would be equivalent? If this is even the correct solution.
My tape drive is controllable and functions well using "mt -f /dev/nst0 status" so it seems to be a matter of LT&T software to detect the tape drive.

I am running Ubuntu 10.04, and i recently purchased an tandberg LTO-4 SAS tape drive. I want to access it and backup data on it. Do I simply just connect plug it into the server,and I should be able to backup/transfer data to the tape drive? Or are there intermediate steps before I can do that. Here are some results from commands that I have typed:

I want to know how to retrival partial files from a lto 4 tape instead of retrieving the complete tape.
View 2 Replies View RelatedI can backup anything that is smaller then a single LTO4 tape, however I have one DLE where the amount of information I want to backup is 950GB (which happens to be on the backup server) but the tape is only 800GB. How can I get this to span multiple tapes for a single DLE?
I have set the tape_splitsize to 5GB for right now, but it is taking forever to backup the volume. Because the volume is larger then the holding disk, Amanda resorts to the fallback_splitsize which I have set to 1GB. My understanding is that this basically stores 1GB of data in memory and then writes it to tape?
Since I have a holding disk of 200GB, is there a way I can write 80GB of data to tape instead of 1GB chunks at a time?
What is the ideal way to backup large amounts of data by spanning multiple tapes and writing to the tape as quickly as possible?

Do You know linux command to clean tape drive ?
I need help writing a script that will copy everything from tape to system directory. I have a Linux box with 3 TB of Hardware space. I am using the following commands
1) mt /dev/st0 rewind
2) tar xvf /dev/st0
3) tar xvf /dev/st0 fsf 1 (Using this to move to the next segment of the tape) and then
4) tar -xvf/dev/st0
I keep repeating steps 3 and 4.
Does anyone know of any existing software to aid in this task? We already offer backed-up data storage to our users, but no means of say arching original data sets for long term storage(NIH, etc rules). Something that could be user initiated, where they login into the archive server, tell it I want such and such files archives, and on its own it takes those files and gives them to a tape library(drive+robot).
View 3 Replies View RelatedCurrently I have bacula backing up the contents of my server on a daily basis (Mon-Fri) on to a tape. There are in total 9 backup tapes so far. One for each day of the week (Mon-Thurs) and one for every Friday in the month (so there are 5 friday tapes). The tapes are all from the same pool and once the tapes are full they should then get recycled. As I understand and from what I have seen, the data from my server backups up to the tape and is then marked with the append status. Every time that tape is used, data is then appended onto the tape until the tape is full. At this point it is marked as full but wont be recycled until all the tapes from the pool are marked as full (so until all 9 tapes are full).
My question is, is there a way of overwriting the data on the next backup on the tape, rather than appending or requiring that all tapes in a pool are full before a tape can be recycled. As the mon-thurs tapes currently cant be recycled until all the Friday tapes have been used. The reason why I dont have seperate pools for the Friday backups and the other days of the week or even seperate pools for each day of the week, is that if a tape is accidently not changed or someone puts in the incorrect tape by accident a backup will still occur. Which is better than no backup!
I'm trying to use wget to retrieve some data from our tape backup utility (HP Command View 1/8 G2 Autoloader). The URL requires two parameters for the info I want to retrieve. I have searched for a few hours and have tried numerous combinations to get the data but the parameters aren't being executed. I have escaped the URL as well.
Code:
wget --user=x --password=x --recursive --no-clobber --page-requisites --html-extension --convert-links --no-parent -O ssi.html "10.0.x.x/inventory_status.ssi?mag_0=1&mag_1=1"

I am a Ubuntu 10.04 Desktop user.
I am searching for a backup software to backup to my hp dat72 tape drive. It is only to backup my data from 1 PC.
I have already found bacula but it seems to big for my purpose. I need an easy and automatic software.
Could you recommend a backup software for my needs?
We have RHEL4 loaded on the server and our tape drive is not working.While taking the backup on the tape using the command tar cvf /dev/nst0 * the system is creating a tar file by the name of nst0 in /dev directory and no backup is being taken on the tape .Please provide solution.

Tape command:
Giving error like below archback is a shell script for the above same command for backup.
I'm having issues with mt commands. For some reason, my server doesn't like backing up directories using tar.
Code:
# tar -czf /dev/st0 /www /home
ends up giving me an error message saying "removing / prefix" and then using the command
Code:
# mt -f /dev/st0 status
gives me an IOCTRL error. I've googled the error code and haven't come up with a viable fix. Thus far, the only way I've been able to check which files are on the tape is:
Code:
# tar -tzf /dev/st0
Of course, without getting the actual directories on the tape in the first place, the only files I've been able to transfer at this point are just singular files within the directories as opposed to the entire directories themselves.

View 1 Replies View RelatedI have a linux server running Red Hat Enterprise Linux AS release 4 (Update 8) that I need to do some unusual configurations to. I have a hospital application written using a database called MSE. Now the provider of this application says they will only support tape because of the fact that this system is using a specialized backup system. Basically the data is housed on raw_data blocks. So what I am looking to do is create a way to USE the SAN to present the server with Hard Drives and be mounted as if it was a tape. Has anyone tried to do something like this before? If so how did you configure that. One solution that I thought would be to just Present a 2TB lun and carve up several partitions cut not create filesystems on them. Then just create a symlink everynight /dev/rmt0 and rotate out the partitions.

Basically the drive is working , I ran the test with the btape program and all was correct. I am basically meddled up with the jargon and the very large bacula documentation. I created some 2 volumes and gave the mounted the tapedrive (labeled) the name of one of them "tapevol2" .... now I can not relabel the tape, I deleted the volume "tapevol2" but still the tape drive is mounted with that name, even though the volume is deleted. If I add ( create more volumes) I can not make the tape to mount with anything different that "tapevol2". I would like to go back to zero and delete all volumes, and mount the tape with one of the newly created volumes, so the jobs back up can run.

We have been using an Ultrium LTO-2 tape drive to perform backups of certain information from our file server. Recently, the data that we are backing up has grown too large to fit on the tapes in their 200GB uncompressed capacity. I have been looking around for a way to enable the compression in the drive, but I haven't found much. I am not using any backup software, so I'm not sure if I'll even be able to. I write the tape using a simple 'tar' command, so there aren't a whole lot of options to be set. Is there a way that I can enable the drive's compression, or would I be better off running the tar command with the gzip or bzip flags?
