How to configure backup server in linux?
1>what method is used?
2>does it required separate machine for that? 3>will the backup server never crashed? |
1. there are many... most people I know use rsync or bacula
2. not necessarily 3. this is going to depend allot on the hardware and what distrobution of Linux you choose. Never seems an ambiguous term. I do know of many Linux servers that have been running for more than 5 years with out ever being rebooted though. |

Hi, meandsushil -

not directly related to the 3 questions posed but common sense with backup that is often ignored, as an assistant tech who has been in the field a few times one common mistake i see people doing is they religiously keep backups on dvd/tapes/floppies etc.. only to keep the only copy of the backup media on the shelf next to the server
think about that for a minute and ask yourself why this is wrong answer: if the location is physically destroyed (name your natural disaster, sprinkler system malfunction, fire, etc..) and your ownly backup is physically on location it will be destroyed as well of course if a company can't financially withstand the destruction of their building this is moot but i have heard of at least one company going under after the 9/11 attacks on the wtc because the backup tapes for all their databases were in the trunk of a car in the parking lot under the building |
When you come in with such general basic questions, it indicates you need to do a bit of research, reading and learning. Then you might have some specific questions that would get more useful answers.
You could start with the book "Backup and Recovery" by W. Curtis Preston, or check out the companion website, Backup Central. Be aware that it is a broad and deep subject. You could also look at the Bookmarks tagged Backup here on Linuxquestions.org. Those should make it clear that there are many answers to your questions. My answers would be that I use a variety of backup tools depending on the situation. My departmental backups use Amanda. I use rsync to replicate certain directories such as radmind across departments. I use a variant of rsync to replicate between machines at home. I have used Retrospect in the past but am disinclined to use it anymore. Sometimes I have a backup server that is separate, and sometimes I have separate machines backing each other up. I often have multiple methods and copies. And while you would like to have all your servers never fail, you can't ever count on it. Plan for failures and have procedures to follow when they happen. Test those procedures. And, of course, always test to see that you can recover using your backups. Recover a file, recover a partition. Test on a regular basis. |

Nah, I'm kidding. It really depends on how you optimize it, what hardware you will be running it on, and how much of a load it will receive |
