Build up home data center and backup policy

Last a few days I re-organized/cleanup my large hard disks to build up a center repository. All legacy data, reference information and current data are stored on the server which is the only data storage. The advantage is that there is no need to synchronize data and it simplify backup. And all data can be accessed anywhere as well.

A new backup policy is defined. It's in fact as important as the hard disk. :) Basically I want
1. robust data management
2. easy and flexible to use, accessible anywhere
3. easy to automate backup
4. searchable by desktop search engine

The general backup rule is:
1. all fixed data are stored on the external hard disk with read only permission.
2. all dynamic data are stored on another partition on external hard disk.
3. fixed data are backup to DVD with snapshots, dynamic data are weekly (monthly for media) archived and ftp to another computer.

Backup of dynamic data can be automated. I am going to write a script to do that automatically. All data is robust because they have at least one extra copy elsewhere.

All data on server are mapped to windows network drive. It's easy to use and new google desktop can index it! And it is really indexing now! :)

Resource now I have
/dev/hda1 system disk 10G
/dev/hdc5 temporary data disk 10G, used for Bittorrent as well
/dev/sda1 user data 15G
/dev/sda2 repository for fixed data and media 205G NTFS
/dev/sda3 shared data 15G

I bought an external Philips DVD writer last week. At first glance it looks not so good but now I like it very much. :) But I didn't try to burn DVD on Linux yet.

By the way, some often used commands for CVS under linux. Tortoise doesn't work with network drive.

CVSROOT=:ssh:sunwei@192.168.11.99:/home/cvs
(if on the same computer, simply set CVSROOT=/home/cvs)
cvs -q checkout [-r tag] -P ejpgl
cvs -q import ejpgl tcvs-vendor tcvs-release
cvs -q commit *.c
cvs -q tag -c TAGNAME

The last thing is that RealView can't open multiple MP3 files. I installed VideoLAN instead following instructions on VideoLAN site in yum approach. But in 'yum update' it's always error that it can't access some server. I use 'yum clean‘ and 'yum install video-lan' without update and it works.
