I am trying Symantec Backup Exec 2010 R2 nowadays. I am planning to implement it in our company.
The total amount of data which should be backed up will be about 20TB. That includes files, SQL databases, Exchange server mailboxes and Active Directory.
The question is: what is the best media to be used for backup? Shall I use HDDs (2TB each) or tape drives or any other option?
