I want to to know how "windows system center operation manager" and "Backup Exec" works with doubled data.
For example I want to backup disk C, D, E and also shared data - lets say S:\. Now some data on disk S:\ are files shared from same server, let it be disk "D:\data\some data". When data is being backed up, do software knew that S:\ and "D:\data\some data" are the same, and just compress them in some way - something like deduplication, or any other compression - or just backing them up twice?
Same goes with SQL - with Backup Exec SQL agent we make back up of our databases and also we back up previously made copies which are stored on some local hard drive (which might be the same).
