Daily backup - typical amount of data that can be backed up in 24hrs. Note: Assumes fully configured product, compression ratio of 1.5, data change rate of 1%, data retention period of 6 months and a 12hr backup window. Actual performance is dependent upon data set type, compression levels, number of data streams, number of devices emulated and number of concurrent tasks, such as housekeeping or replication. Additional time is required for periodic physical tape copy, which would reduce the amount of data that can be protected in 24hrs.
