Ubuntu Servers :: Backup Data From The 2TB Volume To The ( Cheaper ) Other Volumes Combined?
Jan 6, 2011
All my data is stored on a separate device/partition: a 2TB USB disk with one ext4 partition. I have 3 more USB disks: 1x 1TB + 2x 500GB = 2TB right ? I want to backup my data from the 2TB volume to the (older/slower/cheaper) other volumes combined. I am thinking to use LVM to group the 3 smaller USB disks into one 2TB logical volume and use that to back up the 2TB primary volume. Do you think that is a good idea? In case of disaster I can replace the 2TB primary disk and restore from my 2TB logical volume right ?
What happens if :
I have to replace my internal hard disk and reinstall ubuntu? Can I re-attach the logical volume ?One of the physical volumes of my volume group dies ? Can I remove it and replace it with a new physical volume (bound to have other dimensions) ?Understandably I will loose my backup data?PS: running Ubuntu 10.10 .
I have couple hard drives from different linux distro's. on the hdd's are logical volumes created. what i want to do is to backup the data from those hdd's. but when I connect some of them and boot up the system it gives me an error that there are volume group duplicated and it list the UUID. My host system is centos 5. What is the best solution to rename those volume groups or to mount the drives from other systems, so the data will not get lost?
I already have an ubuntu backup server in my location and need this one server to be backed up remotely in another state. this other location is a helpdesk so there's a danger that they can gain access to confidential data. I'll be setting up this new server as an ftp server but need to set the ftp folder to only allow access to the backup server and me. Because its remote on the helpdesk side, they'll need some access to the file system but need to be completely blocked off from the ftp folder where all the data is at. How can I make sure I can keep them away from my data and still be able to retrieve or copy files over without permission issues between both servers?
How to backup in such way that, data will be backed up in every 1 hour...but every time not full data;; only the data/file which have been modified within last 1 hour. Its on locally. And how to back up local data to remote system. Because I have tried with ssh-keygen also , but everytime its requiring password.
I am using software RAID in Ubuntu Server Edition 9.10 to mirror(RAID1) two 1TB harddrives. These are used for data storage and websites.I also have a 80GB harddrive for the operatigsystem. This drive has no backup or RAID at all. Should this drive crash and the system therefore to become no longer bootable, will I be able to recover the data the 1TB drives or should I backup the 80GB drive as well?
Here is my brief hardware and software detail in my production environment : AMD Phenom X4 3.4gHZ (Over clock to 4gHZ, 8G of Memory, 1TB 7200rpm Harddrive, Running Ubuntu server 10.10.My web production environment were pieced together 3 weeks ago.Here is my dilemma. started out with less that 40 users and now hitting 4,000 unique users per day.Now I am thinking I need faster write to disk and backup of data so I am thinking about putting together a Raid5.
I preparation for this.I have bought a new motherboard, AMD Phenom X4 3.6, and 2 more 2TB 7200rpm (Currently, I have a 2TB 7200rpm not used much)Been digging around this forum for posts with raid setup but still not sure how to seamlessly moving the some 10Gig of data from my current running prod environment once I have RAID5 installed on this new machine via the LIVE Ubuntu Server CD.
what the maximum number of logical volumes is for a volume group in LVM ? Is there any known performance hit for creating a large number of small logical volumes vs a small number of large volumes ?
I am now preparing myself to upgrade lenny to squeeze and decided to do a backup on my system. I used backup-manager to do the job and it worked fine. how do you restore said backup data?
I have Fedora Core 8 installed. I would like to reinstall it so as to get back commands that have been lost. To preserve my user data that has been stored in logical volumes, what selections should I make in the installation process? Are these selections essentially the same for Fedora Core 10?
I have a scheduled backup to run on our server at work and since the 7/12/09 it has be making 592k files instead of 10Mb files, In mysql-admin (the GUI tool) I have a stored connection for the user 'backup', the user has select and lock rights on the databases being backed up. I have a backup profile called 'backup_regular' and in the third tab along its scheduled to backup at 2 in the morning every week day. If I look at one of the small backup files generated I see the following:
Code:
-- MySQL Administrator dump 1.4 -- -- ------------------------------------------------------ -- Server version`
[code]....
It seems that MySQL can open and write to the file fine, it just can't dump
Does anyone know of any decent enterprise level backup solutions for Linux? I need to backup a few servers and a bunch of desktops onto one backup server. Using rsync/tar.gz won't cut it. I need like bi-monthly full HDD backups, and things such as that, with a nice GUI interface to add/remove systems from the backup list. I need basically something similar to CommVault or Veritas. Veritas I've used before but it has its issues, such as leaving 30GB cache files. CommVault, I have no idea how much it is, and if it supports backing up to a hard drive rather than tape.
I was reading [URL] which as the following in "Warning": Warning It is not a good idea to configure InnoDB to use data files or log files on NFS volumes. Otherwise, the files might be locked by other processes and become unavailable for use by MySQL. What does that mean, and how can one configure or check to ensure the above is being followed?
System76 laptop, 10.04, 320GB HDD, VMware with Win7 in one VM; want to use Clonezilla as am using it to back up (bare metal backup image) another older smaller dual-boot Ubuntu/XP machine. This System76 laptop is a work machine that I control; the Win7 VM only does a couple of things but they're necessary for work and I don't want to lose the configuration. The reason for the bare metal backup is so if I have to, I can restore and get back to work - something I've had to do on some previous occasions back when I used Windows. Data is no problem - I back that up separately on an hourly basis.
My question is what FS to use on the backup drive; for instance, for the dual-boot XP/Linux work machine I'm currently backing up, I'm using a 30GB external HDD formatted in FAT32. That's OK because 30GB is below the limit for FAT32. But for the newer laptop I'll need a much bigger backup partition. I chose FAT32 for the old one because I know everything on the computer being backed up, Windows & Linux both, is compatible with it. But what FS should I use to back up the new laptop, considering that I'll be backing up the Win7 VM as well as the main Linux part of the machine? I plan to use a backup partition of about 160GB. Could I format it NTFS and have it work with Ubuntu 10.04? Or, conversely, if I format it EXT, will it back up the Win7 VM OK?
Does anybody know any programs that might facilitate the spanning of a hard drive over multiple DVDs? I would like to backup a windows system that may have become corrupted however; but I don't know how to automatically span the files over multiple DVDs (which is what I'd like to do.) I may or may not use Ubuntu, but does anyone know any good applications for this?
We purchased a new database system at work last October, ditching the old system because of a lack of support from the vendor. This is a retail Point of Sale and Backoffice database system. I am not sure what system the new one runs on, but the system we replaced was a Firebird data base. The reason I am posting is because we are now in need of the information contained in the old database which was not completely imported into the new system.
Basically the problem is this: The database in on a Windows XP system and I found a copy of SQL Manager Lite 2008 on the system, which after quite a bit of studying, I figured out how to extract the database into a removable file. I have this file (178MB) on a USB stick in a file called Backoffice.fbd.
My studying suggests to me that I can get into this database with MySQL. I have never used this and have no clue how to do this. All I want to be able to do get into the database and create tab deliminated spreadsheet files for each of the database sections (Customers, Repairs, Sales History, stock files, etc.) Is it possible to do this with Ubuntu and MySQL and if so, can expert suggest one or two things to get me started. While a guided tutorial would be nice because I am not an expert, I am willing to learn on my own if someone could point me in the right direction.
Where apart from ~/.kde4/share/apps/kmail does kmail keep account data, such as login data/names of pop/smtp servers? I wanted to install an entirely clean version of kmail, so I uninstalled/re-installed kmail via YAST. I manually deleted ~/.kde4/share/apps/kmail. After installing kmail I found that the account data of my Yahoo account were still listed in the kmail configuration panel. Shall I delete the Yahoo account within kmail prior to uninstalling the kmail package?
You'd think that with two backups of all my data, which are syncronised twice weekly - that I'd be pretty safe. Fine and good until in a reorganisation of my documents folders,I delete a bunch of files - and don't notice until after I've run the backup - so they're deleted from the backups as well. Cue me beating myself around the head with the keyboard a few times about a week later when I realised.I'd advise against doing that if you have a keyboard like the IBM Model-M - it hurts.Okay, so I figure it's at least worth having a stab at recovering this data. The external harddrive's not had anything written to it since then, so is probably the best candidate. It's formatted as an NTFS volume (1.5Tb).
Now, I DO have a copy of R-Studio for Windows which I bought and paid for a few years agowhen XP managed to destroy itself and the file structure on the harddrive when it fell over installing SP2 (this was the event which lead ultimately to me switching to Ubuntu).I've found this to work quite well, though the initial scan does take a while.nfortunately, it does NOT seem to work from within Ubuntu through Wine. It runs, but can't see any drives. The only Windows environment I have access to now is Vista, andR-Studio seems to hang after running for an hour or so under Vista.
Are there any tools - preferably simple enough that I can get my head around them - which I can use from within Ubuntu to have a scrub through an NTFS drive to look for and otentially recover deleted data? I've found several tools which claim to recover things from ext3/4 drives from Windows - but not the other way around!There are a fair selection of filetypes involved here, some word documents, probably most of interest to me though are some old videos, mostly <5Mb taken on my old phone camera from university. Nothing really mission critical...but memories nevertheless.
What are the options to backup data to CD/DVD from command line interface. Don't want to use K3B and Nero Linux. Want to backup using "tar" like utility. Please suggest good articles or options.If we can use tar itself to backup data to CD. Then how?For example I want to backup my /home directory to a DVD. I don't want to use GUI tools for this.
SB X-Fi Titanium has a FlexiJack: Mic/Line in combined into one jack. The windows driver sets the mode. Linux driver has no such feature and it always works as a mic input. So you cannot use it for "Line in". Just because of this I am going to have a new sound card.
I have several audiobooks that are each split into many small chapters, and I would like to string together about ten of them at a time, so that I don't have 60 4-5 minute mp3 files per audiobook.If I were to do this all by hand, with audacity or something similar, it would get very tedious, so I'd like to know if there's already a program that would do it for me when told which files to string together.
There are md5 and/or sha1 checksum files for the CentOS 5.5 ISO files, e.g. "part 1 of X". However there is no checksum for the combined ISO file. I believe we can check the media at boot time, but it would be nice to have a checksum for the combined ISO's and not just the individual pieces. Any file system should do an error free copy, but there is always the possibility of a copy not happening correctly. Is there any official source for the checksum files I'm looking for?

I have installed also Vista on my PC, but "Documents and Settings" f.e. is void if I mount the Vista partition. In this case its not very important. But a week ago i'd run a XP-Laptop with 9.04 live-CD for backup. That worked fine (The XP was very damaged). I put the 40GB data on my PC through the WLAN during one night without any aid else. All the XP files are well accessible. And I put it back later on a fresh XP.But what would have happen with a Vista-Laptop? Anyone an idea how to reach all Vista or 7 files with a live CD? Or at least from my installed 8.04 to installed Vista.
I think it works alternatively from Win7 running using a USB hard drive adapter if you change the rights on Vista or 7 on the connected hard drive. Not tested.
I have installed fedora 11 in my system. While installing it asked me encrypted password which i passed. But I forgot that. Now the problem is whenever i boot my system before going to root itself it is asking for volume encrypted password, which as i told you i have forgot. Now i am not able to access my hard disk since it is completely locked. Is there any way to decrypt the password or unlock it. Or if that is not possible can data be recovered,which is my primary requirement..
I recently resized one of my Logical Volumes that contained 160MB data from 500MB to 6.5GB. After resizing it, I checked the size of the data via 'du -sh' and found that my data had reduced to 143MB.
Fortunately, I backed up the the 160MB of data on another partition before resizing the Logical Volume. I ran 'diff' on both directories holding the 160MB and 143MB, but there was no difference detected.
how come there is a 17MB difference after resizing?
In case you're wondering how I performed my resize, this is what i did:

I have a multisession DVD-R with an unreadable volume descriptor caused by a bad DVD burning using growisofs. The DVD is not physically damaged. I tried to recover the data reading directly from /dev/hdc but it throws an input/output error. I believe the error is caused by the broken volume descriptor. That's why I'd like to know a way to make a low-level DVD image that doesn't use the volume descriptor. Once I have the image I'll manage to recover the data, but now i can't access anything at all. By the way, i've already tried all this programs and anyone worked:

My primary drive is 250GB and has the root, home and var (I'd read it's good to put var on a separate partition for MythTV which I'm planning on doing) on separate partitions. I have a second 1TB drive that I'll be using to backup the 250GB drive and also host less critical data. I've created two partitions on this drive, one 250GB and the other covering the rest of the drive. I'd like to move the Videos directory out of Home on the 250GB onto the 1TB drive but can't find a definitive way of doing this. Should I just follow this guide for moving the home folder to a new partition? Next question is when performing a backup of the 250GB drive how do I make sure it's going to the 250GB partition on the 1TB drive? Can the different partitions be mounted separately?
I have searched and searched for answers to this question, but I can't find what I'm searching for anywhere. At least with the search terms I'm using.So, my question is, is there a backup software for Linux that backs up not only a user's home folder, etc, but also the user's applications, and its associated data.
I am about to upgrade my mother's computer to Lucid, but I don't want to do that until I can find a backup solution that will ensure she doesn't lose any of her application data. She has a lot of apps on her netbook, so just finding out where each individual app stores its data and backing it up is kind of out of the question. Unless every app that the end-user uses (that isn't run as root, obviously) stores its data in the home folder, then it would be easier.Honestly, I use a Mac and I guess I'm just used to the simplicity of Time Machine, which certainly backs up applications, application data, user data, and even extra executables in all the /bin folders (which Macs don't typically use to store most applications). I've heard TimeVault is like Time Machine, but when I tried to use it on her computer, it wouldn't work because it wasn't compatible with the version of Ubuntu that was (and still is) on her computer.
