So far i believe amanda would be best for this situation and also has good reference. Is there anything else - i would be glad to have space for research and choose backuping solution which fits for my needs best. Thanks in advance! Tim Nelson If you enjoy beating your head against the wall and cursing, I highly recommend Bacula.:-) It is incredibly robust but a little odd/confusing/intricate to set up properly.
However, once it's working, I've found it is stable and reliable. Tim Nelson Systems/Network Support Rockbochs Inc.

I've been using BRU(CLI version) off and on for about 8 years now, the company has been doing backup stuff for a bit over 30 years now. I haven't looked at amanda since 2000, so I'm sure it's improved since, at the time it wasn't usable for me so I went to BRU and haven't seen a need to switch off of it since. Les Mikesell If a disk based archive will work, backuppc (is fairly painless and it's scheme of compression and hardlinking duplicates lets you keep about 10x the history you'd expect. If you need offsite copies you'll have to run an independent instance elsewhere or come up with a clever scheme to copy the disk though.
The massive number of hardlinks it creates makes it difficult to use normal methods to copy the archive partition. Les Mikesell [email protected].

It has awesome compression, and a great web gui that you can use to restore individual files or file trees.
I have even used it on occasion to rebuild an entire Linux server from bare metal (I had to install the base OS first, but it worked!) As Les mentioned, due to the huge number of files and hard links you will run into problems copying the backuppc files off to tape or external USB drive if you try to use rsync or cp for this. Depending on the amount of data.

You can even let users login and have access only to their machine to recover their own files. Paul Bijnens I'm an Amanda user since 9+ years now. Done several restores, even bare metal ones.
Amanda never failed on me. Note that the most important functionality of a backup program is actually the restore process. One of the biggest advantages when using Amanda is the possibility to restore using only the bare bones system utilities like dd, tar, dump etc., very handy when you have only a backup tape and a brand new machine to restore to.
When doing backups from MS Windows, be aware that Amanda can. David Hl??ik wrote: Hello guys, hope i am not making an offtopic Currently we are looking for storage/backup solution in our company.

Amanda is not good for programs (and especially their registry settings and all undocumented stuff done during installs of them). I do the backups of our MS-Windows clients with BackupPC (see the mail from Les Mikesell): very good (but backups are only to disk).
We do not have many MS Windows servers, and most of those are actually vmware instances, which are included in the amanda backups of their hosts anyway. And last but not least, there is a mailinglist with active and friendly people as well, helping you out for most problems (usually much better and faster than payed support IMHO, where you have to argue for an day or two through the firstline helpdesk, before you get someone who understands your question).

Amanda never failed on me.Paul, I bought the Enterprise version of Amanda and was blown away to find it cant do a verify of a backup once completed. You can verify the contents of a single tape manually, but I thought that was a bit of an oversight! Do you guys just trust what you hope was written to tape to be ok, or how do you verify backups?There is the command 'amverify', which you can run just after a backup or even a few weeks later, when you believe a tape has gone bad.
But, indeed, that command verifies only to some depth. For gnutar dumptypes, it pipes the backup image into gnutar to verify, but for 'dump' dumptypes, this cannot be generalized, because the server OS does not necessarily has a compatible 'restore' program (your client could be a Solaris with ufsdump, while your server could be a Linux without ufsrestore/ufsdump). In that case the amverify command limits itself to verify if the bytes can be read from tape without errors, and uncompressed without errors if the image had software compression enabled. Adding checksum verification is currently work in progress. Of course, tapes can fall on the ground, and get damaged, after being verified, so, if you really really want more certainty to be able to restore, there is the RAIT support in Amanda, where you can mirror (2 tapes), or write a N tapes with one parity (N-1 tapes + 1 parity) in parallel. Now, you can loose a tape, and still be able to restore. I even ran a RAIT-mirror with one virtual-tape-on-disk (for easy and fast restores) and one real physical tape (stored offsite for security) for some time.
Worked very well. When there are errors DURING a tape write Amanda will notice, unless your hardware does not detect those. Tapedrives actually have a read-after-write head, that verify the bits that were written microseconds before - if you don't trust those, buy another tapedrive from another manufacturer. One of the frequent errors 'competitive' backup programs make is, that they close after each image (or even a partial chunk), and then reopen the tapedrive again to write the next image.
The current version of Amanda does not even allow appends to tape, just to avoid this, because in the small time between the close and open, there is a chance that e.g. The scsi subsystem gets reset, and the tape rewound. Amanda would have noticed any error here.
Otherwise you need indeed a verify pass to notice that kind of errors. As long as I use Amanda, however, I did indeed not have got any tape that got zero errors while writing, but was unreadable afterwards. Maybe I was just lucky. The feature I miss most in Amanda is the rsync-like stuff.
That's why I use BackupPC for our MS Windows Clients, mostly laptops (using rsyncd), and rdiff-backup (rsync with history) for the remote backups over a slow link.
Hi all, In this article we will learn how to install amanda backup server and cofigure it to start taking backups. It is completely free and based on GPL License. We don’t need to pay any license fee to use this software in live/production environment.
Steps to install amanda backup server. Install centos 5.2 x8664. Get rpm from www.amanda.org/download.php for latest stable version of amanda server. E.g amanda-backupserver-2.6.1p2-1.rhel5.x8664.rpm. install this downloaded rpm using #rpm –ivh command e.g #rpm –ivh amanda-backupserver-2.6.1p2-1.rhel5.x8664.rpm. If there were any missing dependencies then it will ask you to install that first.

It will also create required files and directories. Default configuration directory is /etc/amanda for all configurations. We have 4 TB separate storage for backups. That storage is mounted on /amanda partition.
I have copied all configuration from /etc/amanda to /amanda and created soft link from /etc/amanda – /amanda. Configuration file which holds details about what is getting backed up is /amanda/DailySet123/disklist. Imp configuration about server, tapes etc is in /etc/amanda/DailySet123/amanda.conf.
