Server :: Backup / Restore - Importing LVM Setup At Destination
Jun 8, 2009
I am doing a LVM replicate to another server.
Example: server1.foo.com has / , /boot , swap and few LVM partitions. All are in /dev/sda disk of size 80GB. /dev/sda5 is a LVM partition which has only one vg00 and it has 2 LV's (/var and /usr) and a SAN storage connected to this server which has around 500GB of single partition(a LV partition) called /data and its under vg00 .
Now I have build another server called "server2.foo.com" with same RedHat OS version - RHEL 4 and want to import the same LVM setup at destination. Down time or unmounting the filesystem is not a problem (but am trying to reduce the down time as much as possible). Is there any way that I can take a proper snapshot of whole LVM disk and restore with same setup at destination without losing the data and the lvm file system layout?

Client has a server running 5.5 (I think) and it they moved locations. This server is used in other locations (state) via ssh tunnel as well so they can all access files.
When attempting to boot up I get screenshot 1 (superblock errors)[url]
They supposedly have a backup on a hot swap scsi and I want to know how/if I can restore it using that backup if I cant fix the superblock boot/error issue.
I took some other screenshots:

I would like to create a bash menu script for my home server For instance if i were to type ./script It would then bring up 3 options
a. Create a backup
b. Restore files from a backup
c. Quit
If you were to select a or b it should then ask you were you want to backup or restore from. And if i were to type in an incorrect letter i should get an error and take me back to menu. I have attepmted this a view time now and have magaged to get the menu up using parameters

on my server I have atMail and a intranet site being hosted using mySQL for the database locally, and obviously backing it up would be a good thing. I got the backup package from the list if you use the add/remove software called dump-0.4.etc.. can't seem to find much on how to use it, set it up, nothing. Granted I could be looking for the wrong thing which I'm sure is the case. As of now it's looking like a USB drive is going to be my only option, that will change in the future as this "project" goes further (we are a windows shop trying out Linux, and the next step is going to be adding another server that's a file server at that point we'll probably go to NAS for the backup and then transer that to a USB for offsite/secondary backup).

I'm currently learning to use rsync to backup my music collection. I have a Firefox tab open to the rsync manual page(s) and have been reading man rsync and running experimental rsync operations.I've been doing this for the last 3-4 hours. I've used rsync for this purpose in the past with disastrous results. What was and is once again (due to a month and a half of file pruning) a 9000 file music collection had mysteriously grown to over 25,000 music files and 80GB of data! This was likely due to the fact that I didn't really know what I was doing with rsync and had never spent too much time learning about all the parameters, what their functions are and how they may relate to my goal.Here are the particulars:
* Source drive is a 500GB disk, /media/sata500/music/.
* Destination drive is a 250GB USB disk, /media/FreeAgent/music, connected to the same computer that houses the 500GB disk.
* I want to copy or backup files from /media/sata500/music to /media/FreeAgent/music.
* I do not want to create ANY duplicates of files that exist.
* I only want to add files to the destination drive if they are new on the source drive, like if I rip a CD and add the contents to the source. I want them copied over next time I run rsync.
Here's the rsync command in it's most recently used form, and probably very immature at this point.
Code:
rsync -t -r -vv --stats -i --log-file=/home/glenn/rsync.log /media/sata500/music/* /media/FreeAgent/music/
This appears to have copied all files and folders and I'm satisfied that my goal has been met with some success. To convince myself of this I ran the command and then once it was complete I added 2 new songs putting them in their respective folders on the source drive and ran the same command again. The resulting output was
[code]....
Two files transferred. Exactly what I want.Both folders now house 20,931 files and use 40.6GB. Identical as far as I can tell.What I'm concerned about are time stamps and play count data, etc. Anything that changes the original file. I don't want this data to cause a file to be transferred as I'm afraid that the new file will be created along side the old file of the same name thereby starting this whole music collection expansion thing all over again. I've invested a lot of time and effort to get it pruned down to where there are virtually no duplicates and albums are correct in that they contain the proper songs in the proper order.

looking for a bit of assistance from those that know. i would like to setup an offsite backup server preferably using my current ubuntu 10.10 server.i would like something that has a client that can be used on windows PC's and that is managed so i can controll bandwidth and storage space.it will only be used for storing important files and not full backups of machines.i thought about using something like comodo backup for the clients and just setting up and FTP server but just wonderd if people know of a better solution.

I have 2 servers. One is an operational CentOS + cPanel server and the other is a blank CentOS server. I want to use cPanel's backup suite to backup our customers accounts but I want to do it so the blank server is mounted to the cPanel server, rather than an FTP backup. If that makes sense. I believe from previous experience that NFS is the way to go but I'm not sure.

I have a simple issue that I think can be solved with several different methods. I basically want to create a personal server solution that allows me to do two things:
1.) I want to be able to remotely backup data to my server.
2.) I want to be able to pass traffic through it and use it as a proxy.
I am off to college next year and I want to leave a computer/server back home to do the two things stated above. I was thinking of using an Asus Eee Box PC like this:url
I want a low power reliable machine that will only be used as a remote solution. I won't be hooking up a monitor to it (that is, after I set it up).
It will be on 24/7 for easy access.
I will be accessing this server from a Windows 7 based machine.
I do not mind at all installing Linux on my server, but I am not an experienced coder so I will need software with a GUI that can help me set this all up.

I want to restore all of my configurations (/etc and the like), data and home on reiserFS: is this possible? What to do in order to accomplish that?

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??

I have Lenovo IdeaPad z510 laptop.My HDD SMART status is currently "failure". As my laptop is under warranty I can return it to lenovo. So I want to backup as much data as possible (everything is readable). I currently have 3 operating systems: linux xubuntu 14.10, debian 8 and windows 8.1 (triple-boot?). I want to back up only my current debian installation. There are 3 partitions for debian: root (about 50GB), home (>200GB) and swap. I know that I can backup the whole partition using:
Code: Select alldd -if=/dev/sdaX -of=/locaton/of/backup -something
And create .tar file with the whole home directory.
how to restore it later. In /etc/fstab there are references to UUIDs, and as I understand, with new HDD these UUIDs would be different. And possibly the whole partition table would be different. And how would I restore GRUB?I can't make full image of my disk simply because I don't have disk to store it on.Is it possible to create backup on my current debian installation without actually making full HDD backup? Would it work if I would install debian on new disk, then from LiveCD overwrite it with my backup and modify /etc/fstab to match new partitions?

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 fedora 12 (amd64) on desktop. I was wondering if there a way to backup and restore all my downloaded updates since installation?! In the same manner that debian has aptoncd. I am planning to migrate on all data to a new partition with clean install and then just move the updates there.

I do regular full and incremental backups using dar. All disk volumes are labeled and mounted by label. There is no other operating system installed. I built a new system but due to having to RMA a disk, I built the openSUSE system on a disk from the backup cycle. This Maxstor disk has problems which is why it was moved into an external box and the backup system. I now have a replacement disk and wish to replace the Maxstor before it dies. I initially tried a disk to disk clone with clonezilla but this died complaining that a small target partition was smaller than the source partition. It had created the partition and the start and end sectors were identical. There are no problems with the new disk.
I decided that it would be a good opportunity to test a full system disk restore from the backups. I have in the past restored individual files and partitions but have never restored onto a bare boot disk. I have restored and labeled all 6 partitions. The partition containing / has been marked as active. /boot is included in the partition containing /. fstab is valid, menu.lst is valid, device.map needs editing but this is not a problem.
What do I need to do to make this disk bootable. I have looked through the GRUB documentation but if you try some standard GRUB commands in 11.3 you get messages saying don't do this use YAST. I have seen other suggestions ranging from trying to start the not supported system repair option to using dd to copy the MBR which seemed to trash the partitions in the users extended partition.
The YAST bootloader displays "boot from the root partition". I assume that this is currently what is happening rather than what YAST thinks might be a good idea for next time. I suspect that all I have to do is dd the first 512 bytes of the root partition. If this is the case I can add this to the backup process. While I automate backups I do not automate restores. Each restore tends to be different and I am not sure of the best way getting grub to work on a bare disk restore.

I'm using ubuntu for a few weeks now and i created a backup script that can copy some folders into a .tgz file. Now i want to place back the folders to where they come from and overwrite the original folder. like the /home folder in the .tgz file overwrite the /home folder on my harddrive. I already tried to do this with: tar xvpfz filename.tgz. But after that the folders came in the same folders as the backupfile stands.
How can i do this the right way?

I'm trying to use this tutorial (URL...) to backup my Ubuntu 10.10 (ext3) operating system. I've successfully gotten it into a TAR file on my external hard-drive, but inside the archive are 2 folders: sda5 and media (/media/sda5/), sda5 ofcourse containing my operating system.
I run VMWare as my virtual machine software, but I could easily run Virtual Box if the situation calls for it. On my virtual machine I created an Extended partition, made a 2GB swap space and the rest is ext3 (ext3 space is mounted as sda1) (at this point, Swap is OFF) here is what I've tried to do inside the virtual machine to restore:
Code:
sudo -s
mkdir /media/FROM/
mkdir /media/TO/
mount /dev/sdb1 /media/FROM/
[Code]...
but instead it just creates the directory sda5 under media of the live ubuntu cd Do I need to CHRoot in these conditions? AFTER I get the files successfully into the virtual machine, how do I go about restoring the grub2 bootloader? Right now I haven't tried to restore grub on my hardware, but I would be interested in doing so. There are a vast immense amount of forum posts about this subject, but all are to mixed results. Can anybody tell me the absolute definite way to restore grub2 successfully, I don't want to try something if it's going to mess up my install, whether I've backed up or not.
for further reference, here is a link to the previous (failed) thread I made about this same subject:
