Currently I’m working on a big post compairing several back-up solutions. I found this article from Altaro interesting and contains several interesting points of view. For example inconsistent backups, yes the backup succeeded but when it takes serval hours for a backup to complete many file could be inconsistent. Do you still have a backup you could use for datarecovery?
Also the different types of backup, what is the right one for your situation? The articles doesn’t go into what products from what vendor are available, but for that check out vWorld.nl somewhere this week 🙂 Check it out at : http://www.altaro.com/blog/vss-crash-consistent-vs-application-consistent-vss-backups-post-1-of-2
