Synthetic Backups

我需要解决方案

Hi,

 

I raised a forum discussion the other day regarding synthetic backups and how they use the baseline as a reference, i was advised that a baseline backup that is run at the beginning is made redundant when subsequent incrementals and then a synthetic full are run as this takes the place of the original baseline. I have done a test on this and found that this isnt accurate can some clarify, what i have done is listed below

 

We have multiple D2D folders

 

In my example the baseline was written to D2D1

Baseline run

Incrementals x5 were run

Synthetic Full was run to D2D 8

I then disabled the D2D1 to make sure it didnt reference the original baseline.

This caused the job to pause as it couldnt reference D2D 1

 

This to me means that you have to keep the original baseline for future synthetic backups and if needs be the restore can someone just confirm?
