Scenario A customer is looking to modernize their backup infrastructure. The current
environment consists of a single centralized data center and several remote sites. The
centralized data center hosts all core services and applications. The remote office primarily
consists of sales personnel with 4000 users in North America, 500 in Europe, and 300 in
Asia using file servers. The current backup environment at the primary site uses
CommVault backing up to a Fibre Channel tape library that contains four LTO-4 tape drives.
Currently they are backing up a number of file servers as well as several databases that
have average change rates of 7% daily. Remote office backups are currently performed by
having users copy files to regional file servers that are then backed up to tape. In the past
few months, the customer has experienced problems with getting backups to finish within
their defined windows as well as issues with the tape library hardware. They now have
concerns about gaps in their backup coverage as well as the reliability of the tape media. In
addition, an internal audit shows a large amount of user-generated data is unprotected on
remote user laptops. The customer is looking for a common platform to standardize their
backups. They want a solution which allows for a centralized infrastructure so that they do
not need to rely on remote resources to address hardware and software issues. The other
goal is to move away from tape to a more reliable disk-based solution. Refer to Scenario .
