The backup requirement is for one full weekly backup and a daily incremental backup, retained for one week. The size of the daily incremental backup is 10 GB. The size of the full backup is 250 GB, which exceeds the disk space that can be allocated to a single slot. Therefore, each full backup requires two autoloader slots. Number of slots required Physical disk space required on HP D2D Backup System 1 x 2 for the full weekly backup 4 x 1 for the incremental daily backups 1 x 250 = 250 GB 4 x 10 GB = 40 GB 6 slots required (8 is the minimum that can be assigned) 290 GB 58 Backup scenarios using the HP D2D Backup System
