Ubuntu :: Use The Tar Command With A Tape Drive - Data Is Larger Then 1 Tape

Mar 8, 2010

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.

Debian Hardware :: Getting HPE Library And Tape Tools To Recognize Tape Drive

Apr 3, 2016

I 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.

At the risk of providing too much info here some, possibly relevant, output from lshw

Fedora Servers :: Tar And Mt Commands For Tape Drive?

Feb 26, 2010

I'm having issues with mt commands. For some reason, my server doesn't like backing up directories using tar.


# tar -czf /dev/st0 /www /home

ends up giving me an error message saying "removing / prefix" and then using the command


# 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:


# 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.

Red Hat :: Make A Hard Disk Act Like A Tape Drive?

May 4, 2011

I 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.

Hardware :: Bacula - Setting Up Tape Drive Backup

Sep 15, 2010

I am setting up a tape drive back up, but I am having "fun" with bacula configuration. 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.

Server :: Enabling Compression On Ultrium LTO-2 Tape Drive?

May 26, 2011

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?

I didn't know if I should have posted this in newbie, hardware, or server. I haven't used tape drives in Linux previously; however I'm trying to figure out how to enable an LTO-4 tape drives built in encryption. Im not that concerned with secure key management, I am looking to just being able to load a key into the drive and get the tape to encrypt. Im for a simple command, but I dont even know where to start. If it varies by device, its an HP Ultrium 4 (1760).

General :: Rebuild System From Dump Tape?

Feb 8, 2010

I have a Red Hat Enterprise (AS) 4.8 system and I need to know how to totally rebuild the system from dump tape. I have been making some full level 0 dumps of the system to the attached DAT72 tape drive... In the case the boot disk goes south, I need to reload from tape, onto a new disk drive. I know how to do this in Solaris. I assume you boot from CD to like a mini-root, then configure and mount the drive on temp mount points, restore the sys data, then load the "boot blocks" (like installboot on solaris).
