I use EaseUS Todo Backup Advanced Server for following reasons.

1)I have ever used its free edition, perfect. And I want to try its advanced Server edition.

2)Its average price, normal backup software for SQL Server backup and restore charges too much.

3) It supports SQL Server 2000/2005/2008

4)I like its wizard, brief and informative

5)Its trial version has successfully restored my database recovery and I decided to buy it.

6)Its free, lifetime and good technical email service leaves me good impression.
