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.
