CentOS 5 :: Daily Backup Of CentOS Server To Disk?
Oct 6, 2010
I'm looking for a simple solution to backup my CentOS Server (5.x) on a daily base to a mounted disk. I found the glastree tool but I have no clue if it will work on CentOS.All recommendations, tipps, hints and maybe scripts are welcome. Unfortunatelly I'm an Linux newbie and starting with Linux CentOS a couple of weeks ago

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 have re-installed our operating system (CentOS 5) ,what is the best way to restore our Samba server? Can it be as simple as copying the smb.config and smbpasswd files back into the /etc/samba directory? That's what I am hoping. If I just copy the smb.config and the smbpasswd files back to the samba directory will the machine trusts, users and passwords just work? If not, what is the proper procedure for restoring. Actually i want to make CentOS 5.3 as my Domain Controller, I want to test all Scenario in case of any disaster of DC before putting it into production environment. I have some queries as:
1. Is CentOS 5 is more stable than RHEL 5 etc.
2. How can i take back up of entire samba server if need it in case of any disaster. How can i restore it.
3. How can i use logon scripts like GPO in windows servers.
4. How can add users in samba server and linux at one time with one command.
5. tell me any Web based samba administration tool other than SWAT.

I'm having a very strange issue with cron on centos 5.3 64-bit. I have 3 cron scripts in /etc/cron.daily which run backups. They are as follows:
script1:
#!/bin/bash
/usr/local/bin/backup-script1
script2:
#!/bin/bash
/usr/local/bin/backup-script2
script3:
#!/bin/bash
/usr/local/bin/backup-script3
The contents of the 3 /usr/local/bin scripts are ...
/usr/local/bin/backup-script1:
#!/bin/bash
synbak -s srv1 -m rsync
rsync -av --delete /data/backup/srv1/* root@::share/srv1/
To explain this, the 1st active line does a synbak backup and the 2nd active line rsyncs the backup data to a remote server.
/usr/local/bin/backup-script2:
#!/bin/bash
synbak -s srv2 -m rsync
rsync -av --delete /data/backup/srv2/* root@::share/srv2/
[code]....

Have been playing with Centos 5 and finally got it installed and have done most of the updates. Before I proceed much further it would be nice if I could create a backup/install disc of how it is now. No Data,just the setup and software used etc.Have a dvd rw on the server.I recall mondo rescue installed years ago on a linux server we used.

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.
The CentOS 5.6 is 32bit

I made a big rookie mistake in a script in cron.daily, which emptied the directory when I tested it... now I'm left with an empty cron.daily directory, and from what I know there definitely were more scripts there than only my own. Does anybody know what scripts CentOS 5.4 (Final) needs in the cron.daily?

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 have 2 dedicated servers, one with RTL8111/8168B (rev 02) and one with RTL8111/8168B (rev 01) both running centos 5.3, the problem is like this, all things run great on the dedicated server with NIC RTL8111/8168B (rev 02) until we run backup (cpanel backup) after the backup is finish the server lags , no high load, just lags, the server is a 8 GB ram, i7 quad core, so there is no load problem or someting like this, the second server has also cpanel on it and it has no lag but it has RTL8111/8168B (rev 01) , we think that the problem is with the RTL8111/8168B (rev 02) should we update the driver ?
Here is the output from it:
2.6.18-128.1.10.el5 x86_64 x86_64
06:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02) .....

I was having a problem on my squid server whereby 1 website would timeout daily and return a nscd not found error: [url]....There may be other sites but this is the only one I know of. A selection of other sites still work correctly, which is the strange thing.I have found that by restarting the dns cache everything works again: /etc/init.d/nscd restart.I never know quite when this will timeout so it is not very good for people accessing that site on the server.

I have a CentOS5 server with a 1tb hard drive.There is only 80gb of data on that huge drive and now I want to make a bare metal recovery backup using AcronisMy question is, how can I estimate the amount of time the backup will take and the size of the image file? Is it based on the size of my drive or is it based on the amount of data on the drive?

After I spent some time discovering The BIG BANG of Universe and The Meaning of Life :
I managed somehow to create a script to make some backup of files on server and TAR it and then FTP the archive to another location FTP server and then emails result.
It also measures time needed to complete it and deletes archive older than XX days (set in find -mtime +20) and makes incremental backup every weekday and FULL on Sundays (which suits me bcoz no heavy load).
Files for TAR to include and exclude are in txt files listed each line separate name:
file: including.txt:

I am trying to install CentOS 5.2, and the installation ran out of disk space after running for about 2 hours.I checked the FAQ, and it said 1.2 GB. The disk is 3 GB. The default install was selected, and I think that it checks for sufficient available disk space before installing. Still, it ran for quite a while before announcing that it was out of disk space.The Installation Guide is not very helpful, since there is a blank page where the disk space requirement is supposed to be. I just picked the default installation. A search of the forums on "not enough disk space" did not return much.

I am having new hardware and IDE driver for that hardware as drive disk image (it8213_centos53.img). CentOS 5.3 installation is working fine with drive disk image at USB and CentOS 5.3 at DVD. Our application uses CentOS 5.3 and we build a custom kick-start ISO for installations. Using that ISO client is going to install on all hardware boxes.
Note while installing :
a) No network connection is avalible.
b) No USB isavalible.
c) No floppy is avalible.
d) Only single CD-ROM is avalible.
So, is it possible to build single custom kick-start CentOS 5.3 ISO which contains dirve disk image and entire installation will be done using that image. If so please let me know the steps to build it.

I need to read information from SUN hard disks which are about a decade old. My CentOS 5.6 mount command comes from util-linux 2.13-pre7."mount -t ufs -o ufstype=sun /dev/sdb2 /New" reports "mount: unknown filesystem type 'ufs'", though its man page describes such settings.How could I read an external UltraSCSI hard disk (yes: high pitch noise and only 9 GB capacity) on a current CentOS? Is that possible at all?

I dont know if this is possible or not but here what I would like to do. I have 6 linux server and each has 100GB disk space. All of these 6 box are compute nodes and space are not used really. However, If I can combine 6 servershard disk that will in total 6*100GB gives you quite a bigger space. Is there any tool or ways to mount these drive in one volume instead of mounting individually ?

I have seen that is possible to boot from a USB stick and use a USB memory as hard drive.I have a server enable to hold 6 sata drives 3.5", But I want to use the 6 drives and make a Raid-5 setup for backups 5 -1 spare. /boot cannot be on a raid-5 level 0 or 1. But I want to have redundancy for my OS, them I can install Centos on a Raid-1 using 2 disk, which let me only 4 for the raid 5. I will run a backup I want to have a lot of space.
Using 4 disk for raid-5 2 TB I will have 6TB no spare, no spare is not a good option at least I will prefer 1 spare.Well, I was thinking, the server MoBo have USB support, if I open the box I can see the small entrances, If Centos let me installed on a USB memory drive, can I trust a USB memory stick?t night with bacula.

Is there any way to make a disk image of an active partition? I have to get a complete backup (partitions, MBR, all data files) of my server without bringing it down to do it. I want to have a backup that, in the event of a system failure of any sort, I can quickly restore onto a new, bare hard disk and have the system back up and running. The windows equivalent of this would be something like Drive Image XML, this is the functionality I am looking for.

I am about to write a script to manage daily backup on a USB HDD. The server that holds the data works 24 hours a day and therefor, is seldom rebooted. I have 2 options :
OPT 1 : I mount the usb drive once and for all, and copy the data to it when I need to (twice a day, no more) and never unmount it. Except when the server is rebooted of course.
and OPT 2 : I mount the drive, copy the data and unmount it ASAP twice a day when the time has come to backup the data.

We have had a hardisk crash in our RAID1 webhosting server running CentOS5 and Plesk. We first realized something was wrong when our main site didn't load but showed MySQL errors. We then found out that the system was in read-only state. Something that also happened the day before yesterday, but we could fix with a FSCK. Then the system worked well til around 18 hours later when it crashed with the same sympoms. So, we rebooted the server and wanted to do a filesystem check again. But the HDD wouldnt even load. It was gone. Unfortunatelly it was not realized that the second disk in the system was also not working any more for some time now. Fortunatelly we had our main site backed up externally though. So we could re-install a fresh box and mounted the two drives to the system. We checked the harddisk. One is practically empty (the older one), the other has almost only files in 'lost + found' but these are all "numbered", no real filenames or so.
