Question : Incremental Backups Vs Shadow Copy

I am curious on whats going to happen with incremental backups especially since the purpose is to revert back to a file that was saved at a past time. Since Shadow copy does this and not to mention its built in to Vista enterprise... is there really a need to perform incremental backups... as opposed to doing full backups every day !??

Answer : Incremental Backups Vs Shadow Copy

Ok, you can have RAID 100 if you want to, but is this going to help you in case of flood/theft/fire, whatever disaster?:-) This is why we are doing backups, to be able to survive some disaster.
Of course if you do full backups daily there is no need to do incremental or differential. I have no idea how much dat you are backing up, but it makes a HUGE difference in corporate environment, if you need to backup 500GB or 1-2-3TB. It takes some time to finish such back up job. And this is another reason why to use Incrementals - because it takes less time to incremental backup to be finished. Of course it will take more time when restoring.
It is not possible to state some rule of thumb that will always be true. If we are talking about your home computer with 5-10GB of data - ok.
In any other case it's not a good idea to rely on shadow copies. Their main purpose is AVAILABILITY of data to users. But it's not any fault tolerant solution.
