Hardware :: Upgrade The Two Disks On Machine BUT In Case Backup Image Does Not Work
Feb 20, 2010
I've a question in regards to RAID, im new to the whole RAID thing. Okay, my question. I have a machine with RAID 1, and I'd like to upgrade the two disks on this machine, BUT in case my backup image does not work, is it possible to power the machine off and re-insert the original disks back in and be rocking and rolling without a prob?
I looking for advice on what is the best way for backup on opensuse in case hard disk failure .
I have opensuse as server running samba (with some share folder) and mysql and web service. for mysql backup I run cron job using automysqlbackup script that run 3 times a day (morning , lunch , evening).
in case of hard disk failure, I wish to be put every things on new hard disk in 1or 2 hours.
The place I work has a web/dns server on opensuse 10 up and running hosting a few websites (our company one & a few vhost ones). The box was set up before I got here. Now we are wanting to create a new 11.2 server that is basically a backup / clone of 1st server in case it goes down.
I have been researching the web for a program which will allow me to backup my entire hard drive so that I can restore my system if need be. I am however unsure which is the best one to use if I want to achieve this:Somehow I want to back up my hard drive containing my ubuntu system byte for byte so that if the hard drive were to fail I could simply go to the store, get a new hard drive, restore my backup and be up and running again without having to do any re installments of ubuntu or any other programs for that matter.
What is the easiest program that does this? I would like it to support incremental backup.rsync with the "Back in Time interface"?bacula?
I use the automatic upgrades - they hardly ever cause a problem... until now.
I just applied this upgrade (linux-image-2.6.32-5-amd64) and a restart was required (normal under when upgrading the image). After the restart my SIP phone software didn't startup - didn't even get any errors in the log file... So I checked the "System Monitor" to see if the process was running but not displayed... the System Monitor generates a core dump...
I hope there will be another update to solve this really quickly.... not sure what else is broken. Firefox is still working and so is Skype.
I would like to set up Kdump in case my machine crashes (and it still does frequently) to send the message to putty running on my windows machine (or to my other server running fedora 8).
My preference goes to the windows machine, but I have no clue how to set it up. Is it possible to get the "screen dump" on my windows putty?
My server crashes downloading torrents at high speeds (which is kind of what I want to do)
I do 'mkisofs -iso-level 1 -o image John Smith.txt'. Only an example. When I mount image, ls outputs john_smi.txt. So it has shorten to 8.3 and translated ' ' into '_'. This is in accordance with the manual, although it doesn't say the conversion will be done.
Quote:
-iso-level level ......................... With all iso9660 levels from 1..3, all filenames are restricted to upper case letters, numbers and the underscore (_). ...........................
However, as it did not reject the file name, it should have converted it to all upper case, it seems to me. And -iso-level 2|3 does the same thing.
Code:
root@darkstar:~# mkisofs -iso-level 1 -o image John Smith.txt Total translation table size: 0 Total rockridge attributes bytes: 0 Total directory bytes: 0
How do I reconfigure grub when adding a disk to a machine where both disks have their own MBRs? I have two volumes:Disk 1 - actually mirrored RAID-1 drives managed by ICH9R on the motherboard Disk 2 - a single drive managed by ICH9R on the motherboard, but without RAID. Disk 1 is the "old" disk containing WinXP on the first partition. The MBR of Disk 1 was created by Windows. Disk 2 was built on the machine while Disk1 was unplugged. Disk2 has Win7 on /dev/sda1 and Fedora 12 on /dev/sda7. Obviously, Disk 2 has grub installed on its own MBR.
When I plug-in both Disk 1 and Disk 2 at the same time, I would like to reconfigure grub so that it gives me the option to switch between WinXP on Disk 1, Fedora on Disk 2 and Win7 on Disk 2. (I may also want to install Ubuntu on another partition of Disk 1, but that's a separate issue.) The problem is that when I plug in Disk 1, Disk 1 becomes /dev/dm-0 and Disk 2 becomes /dev/sdc (instead of /dev/sda as when I installed it). (I don't think I can switch this order because I'm worried that Windows will become confused.) So, how do I keep all partitions the same and get them all to work from grub? On which MBR will I need to install grub? How do I configure it to see all 3-4 of my operating systems? Do I fix grub from the Fedora LiveCD?
The mount appears to complete cleanly, however when I browse the directory /winfiles it is always empty.The smbclient command works properly using the same credentials.The /root/credentials file looks something like this
I have to set at Linux server(i don't know which distribution) to check something ,could some one tell me how can i take the image backup and if that possible with other software like gost image.
I tried to add my wife , and when I put in a password for her, this error comes up."Please set a valid user name consisting of a lower case letter followed by lower case letters and numbers." I did all that and I still can't set a password for her.
Can anybody please suggest a backup-image solution for Fedora 14?I made some tests with Clonezilla: it works fine but, please correct if I am wrong, it requires booting from a Clonezilla CD and cannot be used to take an image backup while the computer is running.
If I use Clonezilla to backup my Ubuntu partition I get all sorts of problems trying to re-install Grub2 after image reinstall. If I backup the whole HD will this include Grub so when I re-install the image I get the whole thing back again?
What is best to make a image or a backup. Whit what for program. By a image form what partion do i have to make a image. By backup what directory to backup.
so that when by linux is corrupt i can do a reinstall.
I have 4 different servers with exactly the same hardware. I set up one of them to have a centos install with all the basic stuff I'd like running on each one. I then created an image of the harddrive with the operating system, and stored it on an external drive. I used dd to copy the external image to one of the new machines. It worked fine, everything booted up as normal and with a few tweaks everything was great. The problem is that the drive is rather large (500gb) and it takes days for dd to copy it over. I decided to try a different route, I booted to a usb (using the linux distro on the ultimate boot cd pre-loaded with gparted). There are two partitions on the external drive, a small (100mb) partition which can easily be copied over with gparted, and the larger 480+gb lvm partition.
Gparted doesn't support lvm, so I used fdisk to create a new lvm partition on the new machine, and then pvcreate/vgcreate/lvcreate to re-create the same volume groups/logical volumes that are in the image on the external harddrive. I rsync'ed all the information over from LogVol00, and made the same swap partition LogVol01 (which took WAY less time). I disconnected the hard drive and renamed the volume group to VolGroup00 (initiall I named it differently, since linux doesn't like having the volume groups named the same). I can mount the LogVol00 partition and see all the files as they should be. But when I try and boot up, it doesn't even go to grub, I just end up with a blank screen and blinking cursor. How to make the drive bootable? Alternatively, a better strategy than using dd to restore this image??
My laptop is Windows XP Fedora 11 dual boot. I am replacing it because of a defect. The original laptop is fairly new so I could simply start from scratch and setup everything again. But I was thinking there might be a way to do an image backup and restore. My new laptop will be identical to the old one
I have a fresh install of Ubuntu 10.04 and have configured it the way I like. Is there a way I can make a restore image to use for backups? I know there's software like Acronis for Windows to make bootable images, can you do something similar in Linux?
Is there a way/command to back up all data from a Red hat Linux 4 serve[Including user rpofiles, data, group info, encrypts] either to a Red hat Linux 5.4 machine or as an Image file or manageable resource?
I have a new HP ML150 G6 Server. I had some trouble getting CentOS to recognise the RAID array, but with some help from a LQ user, I got it sorted :-)Now I need to make an exact copy of the system. Normally I would use Acronis Echo Workstation, or the newer Acronis Backup and Recovery 10. However, this software doesn't recognise the RAID array eitherAcronis tell me that they can't help as HP won't supply the source code for the driver, and a quick phone call to HP Support confirms this.So, finally you might say, I come to my question: Is there a Linux based tool that can perform the same action as Acronis? Or... does anyone know of alternative software that would do the trick
I have a CentOS 5.5 server that has just recently been updated to 5.6 running PostgreSQL 8.4 and Drupal for an internal website. The server is also acting as a shared network storage between the Linux server and Windows desktops with Samba.
I just recently purchased a license to run Symantec Backup Exec System Restore 2010 for Linux and the only operating systems that are supported are RedHat and Suse Linux.
Does anyone know of a nice open source solution that we can use to create backup images of the server?
In the event of a server crash, we want to be able to rebuild the server via a bit-by-bit backup image.
I'd like to do a complete backup of my laptop, convert it to ISO, and then create a bootable flash drive with it. I'd like to be able to totally restore, or run (like in Live mode) the image.
I want to restore a HDD image I have to my laptop's HDD while booted off the Ubuntu Live CD.The laptop's HDD is unformatted and has no partitions.I expected this to work:$ sudo dd if=/path/to/backup.img of=/dev/sdaBut I'm tolddd: opening `/dev/sda': Permission denied.
I have decided to remove Windows from my disk, but I want to keep my current install of Ubuntu.
One possibility that sprang to mind was to make an image out of my Ubuntu install.
Since I dual boot, the disk is numbered "SDA2" (extended) "SDA5" (root) and then there is Swap. (Windows is the first part of the disk)
One question sprang to mind:
If I make an image out of it, what happens to the numbers? Will there be any conflicts? Not to mention the question of which program would be best (and easiest to use, preferably with a GUI, since I want to save time, not learn code).
And if I would go for a binary dump to an external disk (to put it back when the destination disk is empty), would the same problems arise? Or would that bring even more problems, like the issue of the swap partition, which I would have to receate, since it wouldn't fit on the "dump disk"?
This is all because the whole thing sounds very similar to placing the ubuntu partition to the front of the disk, which, as I have been told, is not a good idea.
Well I've decided to move all my data from one VPS to another, and Iwanted to know if there was a way from within Ubuntu to make a full system image backup,ch I can then just transfer to the new Ubuntu VPS, and restore it there ..Unfortunately my VPS control does not have any working backup option right now, so I can only make the backup manually from within Ubuntu, if there is a way to do it
