CentOS 5 :: Best Way To Back Up And Restore Installation 'profiles' For Given Serve

Dec 15, 2009

We're trying out a few backup strategies and I had a question pertaining to CentOS installations. I was trying to think of the best way to back up and restore installation 'profiles' for a given server. In terms of a basic backup strategy.I currently back up the /etc, /var, /usr and /home directories with an rsync-based script, which has been working nicely so far.I also have a script which does a yum list installed on a certain configured server. It then 'diffs' this against the output from a base install of CentOS. The point of this is to figure out the packages installed for this server 'profile' so I can restore them.

Ideally, it would be nice if there were a way to generate kickstart files in reverse for a given server config. I was wondering what the best way to do this would be. Currently, I'm concerned enough about failures that I'm imaging stuff using Mondo Rescue.

Debian Installation :: Restore From (Ubuntu) Back In Time

Mar 12, 2016

I used Back In Time (BIT) to back up my data to an external USB drive on Ubuntu 12.04. After problems with Ubuntu I made a fresh install of Debian 8.3. In Debian I have installed BIT and can see the USB drive. However, BIT cannot see the old snapshots. I had thought I would be able to restore on the new install.

Software :: Using Two CentOS 5.5 Boxes To Serve Up Email?

May 16, 2010

I am trying to use two CentOS 5.5 boxes to serve up email. I wish to loadbalance HTTP, IMAP, POP3, and SMTP between the two servers. The servers are not in a cluster (the email software does not require it). What filesystem could be used to distribute/replicate the files between the two servers? I have tried NFS, GFS, and GlusterFS. All of which work but result in a latency that is unacceptable to the end users (webmail clients).

CentOS 5 Server :: Samba Doesn't Create User Profiles On The Fly

Nov 20, 2010

I've got Samba server running on CentOS box. Everything works fine when I use "path" parameter, but I think Samba should create /home dirs for clients automatically. It should look like this:

comment = Home Directory of '%u'
valid users = @"Domain Group"
browseable = no
writable = yes

[Code]....

When I explicitly declare "path" param, it works ok. But I need PERSONAL home dir for every user separately, not one dir for everyone.

Debian :: Log In Appearance Had Changed - Restore Back?

Sep 10, 2010

I did a bunch of updates, in sid, no issues. But when I rebooted the next day the log in had chanded. No problems logging in, the appearance had changed, and you now have to use the mouse to click on your name to open the password box, where before you could hit enter and get the same results. It is not much, but I have been trying to to restore it back with out much luck. I've played with gdm and gdm3 and a couple of other things but no luck. I did see a update for log in but have not been able to figure out the next step.

Ubuntu :: Back In Time - Restore After Re-install ?

Sep 12, 2010

I have my system and software and data on my computer on an internal drive. On that system I have Back in Time backup software. I use Back in Time, to backup my data to an external drive.

Question: If my computer dies or my internal drive fails, I have to completely re-install everything including my system and Back in Time. If I want to restore my data from the good external drive, how can I do that with Back in Time? Doesn't it keep the Snapshots info or preferences on my dead drive? Or do I need to point my freshly re-installed Back in Time just to the data drive and it will recognize the snapshots etc. automatically?

Software :: Tool To Back Up And Restore An NTFS Partition With Bad Sectors?

Jan 27, 2010

I've been using Knoppix "Live CD" 6.2 and partimage 0.6.7 to back up and restore my Microsoft Windows XP system volumes on various computers. However, partimage seems to be unwilling to back up one of these NTFS volumes which has bad sectors, some unreadable data. It hits that and stops. But this appears to happen at the same place when I have already used Windows to find and mark and, I assume, remove from use, the bad sectors. Hmm. I thought they'd be ignored. It appears I thought wrong.

If so, which of several other Linux-based or other partition backup tools may be suitable for the task - to ignore or tolerate bad sectors? The main goal is to be able to update the volume subsequently in a way that may be a terrible mistake, and in that case to restore the previous version. Sometime not too far in the future, I suppose I have to think about replacing the disk.

CentOS 5 :: How To Restore From Image Backup

Apr 21, 2011

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??

CentOS 5 :: Backup, Restore And Crash (in That Order, Unfortunately)?

Sep 30, 2009

this message is a bit long but I've been pulling my hair for 2 days now. I am installing Centos 5.3 on a Dell Powerege R610, x86_64 flavour. That part goes well. next is testing backup & restore. I've tried MondoArchive, that I used on other OS, but it fails to remount the LVM correctly, and disk formatting fails. Now, I am trying another way: boot with centos 5.3 i386 live cd, take the disks online, cpio to a usb file everything but: /tmp /proc /boot /dev /etc/fstab /etc/mtab

then, reinstall a fresh centos to erase the disk (crash simulation) and to simulate the initial restore I would do after a crash. From there, I go again with the livecd, mount r/w the logical volume, cpio -i all my files, and reboot. It sort of goes well. system reboots correctly - it loads all my drivers (even asterisk & dahdi and the T1/E1 card light goes green...), starts KDE, but from there I get an infamous error message preventing me to log in "Your session only lasted less than 10 seconds" - looking in the details, i get this message "could not exe /etc/X11/xinit/XSession default' - but I dont think X11 has so much to do with it...

When I go to a text console (ctrl alt f1), and try to log, no luck either - and no time to see why. I've modified initrd to level 1 - there I get the single user prompt, that's ok - but init 3 brings me to a screen where I cant log (either with root or a user) - there is a clear difference between an incorrect password and a failed login - the later, as soon as I enter the password, I return to a login prompt Now my questions. 1/ how can I make a "system backup" of Centos 5.3 x64 -ie after a crash, I want an image tha t I will restore and bring back OS + Applications (data can be backed up separately) 2/ what is wrong with my restore thru livecd ? why cant I log into the system ?

[Code]..

CentOS 5 :: Backup And Restore On 5.2 Final Release?

Mar 31, 2010

We have a linux server (centos 5.2 final), with postfix smtp server, webmin, usermin and sugar crm
We need to backup all the data, and then perform a restore on a clean machine, without any OS installed yet.

I look into many pages that says that doing a backup on linux it's as easy as pack all the files in a .TAR file. Unpacking the tar will restore the system to it's original state. Also, i'm confused because if we perform a backup and mysql has active connections, perhaps the database would be inconsistent or corrupted. In the restore step, do i need a live CD in order to boot up linux command prompt? �Can it be from any linux version, or only centos version?

CentOS 5 :: Mondo: Kernel Panic Upon Restore?

Feb 21, 2011

I created a CD image of my CentOS installation using mondo. When I booted from this CD and, in the restore process, selected an option to test the integrity of the image, it got to a certain point and said: Failure to execute /init. Kernel panic - not syncing: No init found. Try passing init= option to kernel.The instructions say the kernel may need to be recompiled with certain options.Does anyone know if the CentOS kernel needs to be recompiled for use with mondo? If so, with exactly what options?I'm using CentOS 5.5. dmesg: Linux version 2.6.18-194.el5 (mockbuild@builder10.centos.org) (gcc version 4.1.2 20080704 (Red Hat4.1.2-48)) #1 SMP Fri Apr 2 14:58:14 EDT 2010.

Unfortunately I don't remember exactly what command I used to test the integrity of the mondo image, and http:[url]....the source of the instructions, is currently down.
