Let me know the best software to take backup incremental data
1. I will backup all employee's microsoft outlook pst files on the file server
2. and then, backup these files to strage server. ( disk to disk backup)
3. finally, Tape AutoLoader will be connected to Storage server , tape backup will also be taken.
These outlook pst files would become up to 5 Tera Byte totally in the future, therefore I consider it is better to backup only incremental for daily backup.
That means that if a certain part of files changes, only the incremental changes are replicated and not the entire file.
In these senario, what kind of backup software would best for me ?
Are there any software to realise this ?
I don't want to take much time to backup full data for daily backup.
