Ubuntu Installation :: Accessing The L-TO-4 SAS External Tape Drive And Backup Data On It?

Feb 28, 2011

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:

Quote:

ls /dev/tape/
by-id

Quote:

ls -lt /dev/tape/by-id/

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.

Software :: Bacula And Overwriting The Data On The Next Backup On The Tape

Feb 22, 2010

Currently 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!

Software :: Use Wget To Retrieve Some Data From Tape Backup Utility?

Sep 30, 2010

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"

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.

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

Ubuntu :: External Hard Drive Will Not Let Backup Files?

Jan 10, 2010

I've been working at this for the past 2 days now. My computer got some kind of virus or something that has caused it to loop at startup and continually reset. I run an XP OS on a Gateway. I desperately need to backup my files, because the person who had my backup absently deleted my stuff. I was able to boot up using an Ubuntu disc and I'm in it right now, I've found my files, I have an external hard drive. The problem:First, it wont let me paste into the hard drive. If I drag, it says "Error while copying to "/media/FreeAgent Drive". You do not have permissions to write to this folder." I've mounted the external drive, nothing changes.

I've gone in to properties, is says under permissions that the owner is root, folder access is "Access files" and at the bottom is says "You are not the owner, so you can't change these permissions." The drop downs where I need to change permissions is in gray, so I can;t change it.So next, I tried "gksu nautilus", went to the drive through there, and it let me use the drop down selection under permissions. I tried to change the folder access and I got this message: "The permissions could not be changed. Couldn't change the permissions of "FreeAgent Drive" because it is on a read-only disk." So I tried changing the file access to Read and Write. It didn't give an error, so I thought perhaps it finally worked. I hit apply, and tried to put my files in. Once again I got the message from before that said I didn't have permission. I tried to change the owner so it was no longer root and I got "The owner could not be changed. Couldn't change the owner of "FreeAgent Drive" because it is on a read-only disk."I'm getting so frustrated right now. These files are VERY important to me! The hard drive I have is a Seagate FreeAgent desk 500GB

Ubuntu Security :: Scanning External Windows Backup Drive?

Feb 15, 2011

I've been struggling with the problem of scanning an external drive that is used to store the backup from a Windows 7 machine. The Windows 7 machine was infected but the user continued to backup to the external drive. He has since formatted his machine and reinstalled Windows 7, but now he would like restore whatever he can from the backup on the external drive. I've been attempting to scan the external drive for viruses using ClamTK by connecting it to my laptop running Ubuntu 10.04, but it has not worked. There is supposed to be about 10 gigs of backed up data, but I haven't seen any. I don't know why it is not mounted.

Fedora :: Cron Backup Permission Denied On External Drive?

Aug 28, 2010

I have a cron backup scheme in which I rsync, then tar, then copy files on my internal hard drives to an external (USB) drive. When it works, it works. But I often get a "Permission Denied" message for all of these tasks. how the external drive is auto-mounted so I edited the etc/fstab so that the owner of the cron job is also the owner of the external drive (I think. Unfortunately, I'm not at that machine right now (it's at work), I can't give the exact fstab line (I will post it as an update to this thread next time I am at the machine).) BUT, I still get times when the cron backup runs fine and other times I get the Permission Denied. This is a shared machine that is dual-booted, so what I *think* is going on is that when the machine is rebooted to Fedora, but nobody logs in, I get a Permission Denied for the cron backup. It seems like on days when someone has logged in as the main user and left without logging out that the cron backup runs fine.

General :: Back Up Initial State Of External Backup Drive?

Jan 1, 2011

I've picked up an HP Simplesave external drive. It comes with some fancy software that is of no use to me because I don't use Windows. Like many current consumer-targeted backup drives, the backup software is actually contained on the drive itself. I'd like to save the drive's initial state so that I can restore it if I decide to sell it.

The backup box itself is somewhat customized: in addition to the hard drive device, it presents a CDROM-like device on /dev/sr0. I gather that the purpose of this cdrom device is to bootstrap via Windows autoplay the backup application which lives on the disk itself. I wouldn't suppose any guarantees about how it does this, so it seems important to preserve the exact state of the disk.

The drive is formatted with a single 500GB NTFS partition. My initial thought was to use dd to dump the disk (/dev/sdb) itself, but this proved impractical, as the resulting file was not sparse. This seemed to be because the NTFS empty space is not filled with zeroes, but with a repeating series of 16 bytes.

I tried gzipping the output of dd. This reduced to the file to a manageable size — the first 18GB was compressed to 81MB, versus 47MB to tarball the contents of the mounted filesystem — but it was very slow on my admittedly somewhat derelict Pentium M processor. The time to do that first 18GB was about 30 minutes.

Software :: Backup Of Data To Both Networked Desktop And USB Hard Drive?

Mar 2, 2010

I am under orders from She who must be obeyed that I must fully backup her data as she had a loss of information due to a hard drive failure.Presently I am having her make available her info as shared documents on her XP system and I am copying this data over to my Ubuntu (Karmic) desktop. I would also like to have a USB Hard Drive save the information in order that I can safely store this away from a live system.

So far things are working not too bad but She wishes to have all her backup that was available on DVDs and salvaged from posted material assembled as one complete resource. I can with some effort put this into some semblance of order but do not feel like doing the work twice.I would like some method of easily copying / transferring data to the external HD. Additionally I would like to be able to update data daily and be able to with minimal effort have this synced onto the external HD.

General :: Good Backup Utility / Script / App / Got External FAT32 Drive

Mar 10, 2011

I am working from a laptop where all my work is stored on a 80GB drive. I am now also an owner of an external 250GB USB hard drive, formatted with FAT32. I want to keep it FAT32, so that I can offer some of my files to people that run Mac OS or Windows and I don't want to have them install ext3 for windows and what not.I am in need of a strategy which will allow me to keep a mirror of my laptop drive on my new external drive, i.e. no history / versioning required. However, I do care about file permissions. The files don't have to be stored as-is, they can be stored within a large (80GB?) tar file, that is fine - it would be easier for me to coerce people to open a .tar file than to install an ext3 driver for their OS, I suppose. I don't think I can keep file permissions otherwise, can I?

I have previously used a self-written sh script that used rsync to keep an up-to-date copy of my laptop filesystem on a USB flash drive, but in that case I had the flash drive formatted with ext3, so no problem with file permissions there. This time, it's trickier.

General :: Multiple Distros - One Data Partition - External Drive

Apr 8, 2010

I've got an external hard drive with one large data partition on it. I also have four computers to connect it to (individually, not at the same time). Three machines are running Slackware and one is running Ubuntu 9.10. I need to be able to just plug the drive into whichever machine, mount it (preferably to the same location each time) and not have to worry about user permissions and such. Do I just chmod 777 all the files and folders or is there a better method for different 'users' to access the same partition? And how about mounting to the same location each time?

Now the second part of my question I'm pretty sure I'm not able to do but just in case..... is there any way to encrypt the information safely and make it compatible with a Windows XP machine?

Server :: Cron Backup Failing / Need To Browse Tape

Feb 9, 2010

we have a server that runs a backup (cron job) at 9:15 every night. When I log on in the morning I have mail message that gives me a long list of all the files that were backed up the night before. For a couple of weeks now, the mail message gives me an empty list. Yet, when I run the same job manually from a #prompt, it runs. I am not able to run this job with cron in the daytime because too many users are in it. I wanted to browse the tape to see if the backup is really failing to copy the files or if they are on the tape and the mail message is bogus.

Since the backkup was done with cpio instead of tar, I'm not sure if I can browse the tape with restore -i anyway.What would be the best way to browse the tape on /dev/rmt/1 without actually restoring anything ?This is an ancient DGUX system, not Linux, and I'm not a unix expert I just inherited this server recently, but a lot of things are very similar to Linux and it looked like this might be a good place to ask.

OpenSUSE Hardware :: Restoring Data From A External WD Elements Hard Drive?

May 29, 2011

(Just to clarify: This has nothing to do with the 11.4 mount problem with external NTFS drives that is stickied in this forum.)

I have this 2 year old WD Elements drive (500GB) that is NTFS formatted and that I've used for backup all this time, until a few months ago it failed to be recognized by any computer. The power supply is working, so I first requested a new cable, which didn't help, and now I received a replacement. But still I would like to save some of the data on the hard disc. I need to have this figured out within this week as I have to return the old drive, or they will charge me for the new.

So far, the only software to still recognize the drive was a WD analytical tool for Windows. It didn't find any problems or show any error messages as far as I could tell. They recommended using testdisk to recover the data, but testdisk doesn't recognize the hard drive in the first place. I also tried KParted, but no success.
