Free BACKUP Software for windows , FBackup

As many of us understand that data backup is an essential task of computer security. Once our server or desktop or notebook is corrpupted, restore data from backup can save us from the hell.
However, much backup software is quite expensive and not affordable for home and personal user. If you have some computer language skill, you may create a simple backup script using a batch script or PowerShell script in MS Windows. Unfortunately, the majority have no such skill.
The good news is that some free backup software can be found on the internet. One free backup software, FBbackup, can be found in http://www.fbackup.com.
Fbackup provided a simple interface for general user to select document, movie, music files in your computer to various media, such as USB Drive, CD-RW, FTP server or network shared path. You also can set the auto backup tasks according to the schedule you like.
FBackup has a clean UI, easy operate, you need not have to learn complicated procedure. One word: Simple. Worth to try!
If you like more feature, Backup4All (http://www.backup4All.com) is a professional of FBackup.

密碼設定

最近Yahoo被盗帳戶並在網上公開密碼,在公開的密碼中,原來有很多人都不注重保安,有多人只使用"123456", "password", "123456789" 等作為密碼,但現在好多人都好幾個電郵,幾部電腦,還有很多其他需要登入的網址,如果每個都要設定複習的話,都幾難記得,但隨便設定一個密碼,又驚被人入侵,的確幾頭痛。 

要設定一個易記又複雜的密碼確是有點困難,加上有些網站要設定密碼的時候需要在密碼設定時要包括大小寫,數字及符號,實在令一般使用者難以招架。 

起初,我都好似一般使者一樣,使用一些簡單的密碼,後來因為一些網站需要複雜設定使頭痛,又驚設定後又不記起,所以我想必需要先設定一套系統先,才設定密碼:
  1. 密碼一定要有足够長度,例如至少有八個字母。 
  2. 一定要包括大小寫英文字母、數字、符號。 
  3. 一定要易記。 
例如想設定密碼: "password":
  1. 長度足够,八個字母長。 
  2. 大小字母,最簡單的是改成 "Password", 將第一個字改成大寫或英文單字的第一個字改成大寫字母,例如: "computergame" 改成 "ComputerGame"。 
  3. 插入數字於密碼內。有些數字和英文字母很像的,例如,s和5、l和1、g和9 ,G和6、E和3、h和4、z和2、o和0等,所以 "Password" 可以改成 "Pa55w0rd"。 
  4. 同點3一樣,插入符號的方法是有些符號和一些英字母很像的,例如:l和!、a和@、s和$、s和&、l和|、g和,等,所以 "Password" 改成 "P@$$word" 或 "P@&&word" 。 
總合以上要點,"password" 可以改成 "P@&&w0rd" 或 "P@$$w0rd",這樣的密碼就可以比較易記,又可以符合複雜密碼的原則。不過,不要用以上例子"P@$$w0rd" 或 "P@&&w0rd" 做密碼,因為太多人知道這個密碼了。
