Backing up My Linux servers


Hi,
Am relatively new to linux.i have two Linux servers in my office.one of them runs Debian ver. 5.0.3 and the other runs Red hat(i dont know the how to check the ver for Redhat).The debian server is configured as a mail server and the the Redhat server is configured as webserver.Am not the one that configured these servers.I would like to know how best to backup the servers so that in an event that the Harddisk or any device fails,i can use the backup to restore the system to some point before the disaster.I want to be able to do this without having to call
the people that installed these servers.If possible,i would like to use a simple to use backup tool that has a Graphical user interface,if not i would go for a straight forward simple method with easy steps to follow.Your help will be highly appreciated.
Regards,
Edwin.

Haven't used it myself but many recommend Bacula:
http://www.bacula.org/en/

Are you already backing up other systems in your office (e.g. Windows)? If so it may be whatever tool you're using for them has clients for Linux. Here we use Symantec (Veritas) NetBackup for all of our servers, Windows, UNIX and Linux.

By the way: To check version on RedHat just cat /etc/issue and/or /etc/redhat-release.

Backup ups

Hi,
I have just installed Symantec Exec 12.5 on a windows 2003 server,am not very familiar with it becuase i have always hated symantec products,anyway,how would i use it to backup the Linux server?
about Bacula,are there straight forward instructions i can follow so that i try it.I will have to build my off the newtwork server to try this because i dont want to end up messing the systems when i dont actually know how to re-build them
Please help and thanks so much

Bacula is powerful but not easy to configure (browse the Backup Central Bacula forum to get an idea of how people struggle with it).

Amanda is reputedly simpler to set up but has no graphical interface in the community edition -- only the commercial Zmanda version has that.

AFAIK Linux does not have a free, simple, GUI-driven backup utility.

Backup Exec is NetBackup's little brother - I've only seen people talk about Backup Exec on Windows - not sure if it has a Linux version or not.

Symantec didn't initially make NetBackup - it was made by Veritas which was bought by Symantec a couple of years ago. NetBackup is designed for centralized backup management.

Giving us a little more information about your own background and the network, systems and resources you have would help us give more explicit and appropriate advice. You've posted this question Newbie subforum and you made reference to not wanting to have to call the people who installed these servers, so that would imply that your own background in linux is minimal. But depending on how much you know and how much you want to learn, the advice might vary. Also, if you have the financial resources, the advice may vary. If you have external disk space or tape libraries that would influence the advice.

I'm not familiar with Backup Exec, but according to Wikipedia, it can handle Red Hat Enterprise Linux and SUSE Linux Enterprise Server. Since it's proprietary software, you are dependent upon them to provide packages for whatever Linux release you are using if you go that route. Call them and ask them.

With more information, we can provide more guidance.

Well,i dont know exactly what i should say about my background,are you refering to my Education,my Networking/Computer knowledge?Please guide me,i may just give you irrelevant information.But regarding the Network setup,i have 2 windows server 2003,one of them is both an application and file server(Member server) and the other is a Domain Controller,The other 2 servers are Linux servers,one is running Redhat and the other is running Debian.The Redhat Server is a Webserver,the Debian server is configured as our Mail server.Thats all about these servers.The Backup Exec 12.5 is installed on the Windows 2003 Member server.We have about 30 client computers on our network.
about my wanting to learn,yes am very interested in learning Linux because of these servers am managing.i have always delt with Windows until now.About resources,i work for a government institution and sometimes they are quite a problem where money is concerned,there resources are not readily as much available.
I will be contacting the providers of Backup exec and find out from them but if anyone out there is willing to help,i will give it a try.But i have developed this interest in Linux and would like to switch from windows to Linux in terms of Preference.
i hope this information is sufficient choogendyk,if not please say so
and thanks to all of you that are trying to help.

This page shows there is a Backup Exec agent for Linux:
http://www.symantec.com/business/pro...cont&pvid=57_1

Note that it only shows Suse, RedFlag and RedHat Linux as supported. You may be able to get it working on Debian but Symantec won't support that. (This would be true for NetBackup as well.)

OK, well, we still don't know anything about available disk space, amount of data, tape library, etc.

Here's my thoughts. Backup Exec is going to charge you more money for adding each machine that you want to backup and perhaps each feature you want to add (support for particular databases, etc.) On the other hand you have it already. Presumably you have either added disk space or a tape drive or library on the Windows server that is running Backup Exec. The easiest way out is obviously just to throw the money at it and add the Linux servers as clients, assuming the Linux servers don't have too much data for the capacity available for backup. However, if your environment changes, and/or you add more Linux servers and grow the data capacity there, this could get you into a situation of constantly spending more money on Backup Exec.

The alternative would be to develop a separate backup system for the Linux side. That might require some additional resources in terms of disk space, tape drive, or tape library. But, being a bit more radical, you could move those resources from the Windows servers to the Linux servers and have the Linux servers take over the backup responsibilities for all of them. In the long run, especially, if you add more Linux servers, that would be more cost effective, because you wouldn't be constantly throwing more money at a commercial solution. The trade off is that you are taking more responsibility on yourself. You have to learn and implement the systems. Although you could go the middle ground and pay for support. You would have to decide where to balance it.

If I were in your situation and was allowed the initiative, I would implement Amanda on the Linux servers. You can either go it alone with the community edition, or you can get contract support through Zmanda. You can find documentation on the Wiki, and there is a Quick Start guide that you can follow to get set up. You'll probably want to do a bit of reading through the Wiki to familiarize yourself before getting started. Since you seem to be new to Linux as well, you may have a lot of ground to cover. Maybe get yourself a setup that you can mess around with to learn Linux.

Thanks so much for your thoughts.Well the Debian Server has only used 21gb,the free space is 270gb.i would use it to back up and hope that after every backup,i can mount an external drive to move the backup from the server.
The Redhat server has used about 2.2 gb and has free space of about 310gb.I would do the same with regard to backup on this server aswell.

I tried to check if backing up using Exec has included these linux servers but the system shows they are grayed out.i think they will require more money to include Linux systems.At the moment,my server have not accumulated so much but with time i know i will need to do alot.My fear at the moment is lossing the information and the configuration.If it is possible,i would rather have a system backup that can backup the Linux Servers on each of them.I dont mind having each on the two linux servers.As information builds up,am hoping i can learn this linux animal and get cracking like you gurus.
If there is one that has straight forward documentation,i will be glad to read through and learn.But i must say i will have to Create a Test Server on which i can learn otherwise i might spoil these servers and get sacked so quickly
I hope these will help.
Thanks yopu guys.
