let's talk about storage technology you used now

As a system administrator I think the most difficult and the most complicated is how to make a backup and DR plan for the whole system. Of coure except you have enough buget to buy hardware and software. In IT there is no problem about technology with enough money.

It seemed in here it was very popular to use VxVm(command begin with VX) or volume manager software (command begin with meta).

When we made this plan in China, I never did such thing in OS server, just use disk array with storage server, and in this server choose to use mirror, hot spare or something else and use fiber channel swith connect to differe server, each server normally connect to two fiber channel switch,for case one broken the server still can connect to disk array, in the disk array you can have different partition which maybe from one physical hard disk or different one, but for server it doesn't need care it just choose which partition it use to install OS or set for different application. If one disk get some problem just need do it in storage system not in the application server. Of course this cost lots of money.

But in here at moment I use one funny way to backup all the important data, we bough one backup software ARCServe (before I came) only just for Windows version(sounds crazy). I need backup all the data from all linux server to this Windows server with ARCServe software, but I cant use this software directly, I use backuppc+cygwin+rsync+cron finally get all the data to this server, then use ARCServer do some offsite backup. The company just want safety and stabilty without any cost, maybe they think I have magic power.

I don't have much knowledge in this area, if something wrong please let me know and I prepare myselt 100% to learn from you.

We can put our backup way here, which software you use and backup future maybe we can help each other to be a expert in this side.

Thank you for your  time.

all the system can be protected by two way: disk mirroring and system backup, and these two way can make system more stronger.

ArcServe does have Linux agent. If it can make your life easier, why not ask your company to buy a few licenses for it.

The reason were:

First my supervisor though it didn't necessary to buy license for linux server.
Second it was my seconed month in this company at that time, maybe I just wanted to show off, so didn't try hard to buy license, you know sometimes ourselves make our life harder.

But here I really want to hear some guys' experience about how to use VxVm and and volume manager software.

how to set disk mirror, how to set HA.

It seems people have no interesting to such topic, at leat less popular than the topics like somebody want to find girl frined or boy friend.

VxVM（VxXX) 应该是Veritas Volume Manager的命令，命令太多了，这里使用很普遍的，也要license的。如果要了解上网找个Veritas Volume Manager的document看看，很多的。

记得以前实习的单位，备份都是传到意大利去。。。不知道这个算不算？

Sorry, maybe I didn't make it very clean, I don't justt want to know some command, I want to know people how to plan and perform these things, like plan some project you need combine everything together, not just command, like when you use VxVm and Volume manage software, these cant load before OS, you need think it's advantage and disadvantage. And you cant always use one tool or one platform to do data storage.
