I need to protect data found on multiple CIFS shares, totaling about 40 Tb of data.
I currently have a backup schedule where i take a full backup monthly, and then incremental backups daily thereafter. The problem is that the full backup takes multiple days to complete.
Would it be recommended to take synthetic full backups monthly instead of the fulls?
What are the drawbacks of never taking another full backup and going with monthly synthetic fulls only?
