We are running backup softwares for incrementals/differentials and full backups with variouse softwares currently using dirvish scripts + amanda .. what is everyones views on other opensourced backup software? is there anything better or other options we have missed? We are looking at backula as an option? any thoughts?

I wanted to recommend you to take a look at Bacula, than I saw it is already on your list. Bacula is very nice peace of software. It can do almost everything that very expensive products from Veritas and Legato do. The only thing it is missing is a nice GUI. You'll need to configure it using your favorite text editor. It can be a bit complex to configure, however it does come with good default configuration files that you can use to build on. However, you should read documentation and really understand how Bacula works before deploying. It is much more powerful and therefore also much more complex system than Amanda.
It is based on three separate components. The center piece is Director. This is basically backup server. Other two pieces are Storage Daemon that handles the storage (you can have as many as you like, it can run on same machine as Director, or on dedicated machine, or even on the client) and File Daemon (this is basically the client).
The storage format isn't standard (so you can't simply take the tapes and run tar or restore commands on them, like you could with Amanda). It also needs SQL database (MySQL, PostgreSQL and SQLite are supported at the moment). There's couple of utilities distributed with Bacula that allow you to read and extract data directly from tapes (in case you loose your backup server or SQL database), and/or recreate SQL database from content of the tapes.
Bacula also has some nice security features. You can use SSL to encrypt communication between all three components (Director, Storage Daemon and File Daemon), so you don't have to worry of somebody sniffing your /etc/shadow while your network backup runs.
It also supports encryption of the backup on the client machine. That means that the data is encrypted. So even if somebody steals your tapes, he can't do anything with them. He would need decryption key, which is normally stored on the client machine (this allows you to centrally backup several departments or clients that don't trust each other, or you). Also, think offsite tapes stored in "trusted" location somewhere far away.
There are some very interesting features planned for the future.
All in all, very interesting project. Something worth including into repository such as centosplus or Dag's.

I'd take a bit of an issue with your last statement, there. Amanda's best feature is its *very* powerful scheduling algorithm. Essentially, amanda tries to ensure that, within the parameters you set for time between full backups, each night's backup run backs up about the same amount of data. This is very handy when you are, as I am, backing up ~10TB of data to small (even LTO3 is small when you're talking that much data) tapes.
AFAICT, all scheduling with bacula is user driven. Thus you end up with the traditional *nix incrementals on weekdays, fulls on the weekend shuffle where your fulls can take a *long* time. And that doesn't work so well, e.g., when you're dealing with grad students who work on weekends.
If I'm wrong about bacula's lack of any sort of scheduler, I'd be happy to hear about it. But, for me, amanda is a rather powerful and complete solution -- moreso than bacula.

I never said there's one backup solution that fits everything and everybody. It would be as silly as the labels on kid's Halloween costumes ("one size fits most children", while in reality the costume doesn't really fit on most children).
I simply recommended solution that served my needs quite well. And left to the others to recommend other solutions.
From time to time I do miss Amanda's self-adjusting dynamic scheduler. Without going into details (that might easily result in needless "my daddy has more hair on the back than yours"), there are other benefits of Bacula that are more important to me. I'm doing quite well by simply defining different schedules for several sets of backup clients. Works almost as good. Plus I know when particular full backup will kick in.

I use backuppc ... which is great if you have a PC to designate as a backup machine.
I do not backup to tape, but to a separate machine. It is very easy to recover specific files with the web interface.
I don't have any idea if it is good as tape backup front though.

If you are going strictly to disk or with an occasional archive to tape, backuppc is great because its compression and duplicate linking will hold about 10x what you'd expect online and it has a nice web interface for browsing and restores. In normal operation it is 'full-auto' - even more so than amanda since you don't need to swap tapes.

Hi All, I' m looking for NVIDIA network contoler driver for CENTOS . I'm currently using HP pavilion DV2007ea notebook with CentOS.

What chipset is the notebook using? CentOS 4.4 has a recent enough kernel that all but the most bleeding edge Nvidia chipsets should be supported.
Cheers,

nVidia used to distribute their own nForce drivers for their chipsets that you could download from the same place you got the video drivers, but the last time I went looking they encouraged users to use the existing drivers already provided by their distributions if available. For example, the open-source "forcedeth" driver works with the nVidia ethernet. For more details, check http://www.nvidia.com/object/linux_nforce_1.11.html.
I'm using forcedeth for the ethernet adapter on my DFI NFII Ultra Infinity motherboard (nForce 2 chipset) with great results under CentOS 4.4. I've got a line containing "alias eth0 forcedeth" in my /etc/modprobe.conf file and everything works fine.
Hope that helps!
I'm using centOS 4.4 32 bit on my HP pavillon dv2007ea notebook . Everything is ok. But I still got same problem: my Nvidia ethernet control is always disabled. when enabled it I got my network area OK ,But about 10 to 30 minutes I got it disabled again. Of courses I got latest REDHAT drivers for NVIDIA on linux Nvidia site but I still got wrong network. Any help welcome. koff.

I am looking for the answer to the same question. I have got amanda going (but not used in anger - just doing my first Centos install for my home server). Just today got amanda to write and restore some data.
So my requirements:
* cheap/free * multiple backups per tape * fully automated backup each day * easy recovery (happy with either a Kdat type GUI or amanda type) - needs to know which tape to recover the latest (or chosen) version. * ideal for a home network (mixed Linux Windows)
The only thing I don't like about amanda (so far) is that it needs a new tape each backup, mainly because I'd like it to be a completely automatic backup, only requiring the tape to be changed when full (or maybe each month).
I typically don't backup much data each day (because it's a home network), so I'd like to be able to store multiple backups on each tape. I have 20GB Travan tape drive, so that's enough for a complete full backup and several incremental's.
I want something cheap (ideally free).
Looking at Kdat (but that doesn't seem to recognise my tape drive and not sure it's automated) and tar (but that isn't going to keep track of what's where if I need to do a recovery)
I've had a (brief look) at the Bacula website and it looks like that will do what I would like - anything I've missed? --

If you have enough holding disk, just leave the tape out until you hit about 20GB worth of data. I do this here at work on a weekly basis - holding disk is a pair of RAID 1 disks, then once a week I pop a tape in and it flushes the entire week's worth of data.
