Report storage space

When you estimate the amount of space required to store a report in archive storage, you must consider the size of the report, the compression ratio achieved, and the length of time that the archive storage manager maintains the report. archive storage can be optical storage or magnetic tape. Use the following calculation to estimate that amount of space required:

Figure 1. Calculating archive storage space

     ArchiveStorageSpace = ( Data per month * life of data in months )
                            * compression ratio
                                * 1.1

For example, if you plan to store 8 GB of report data per month, the archive storage manager must maintain the data for seven years, and Content Manager OnDemand can achieve a compression ratio of 3:1 (0.33), you would require approximately 244 GB of archive storage space:

     OpticalSpace  =  ( 8 GB  *  84 )
                        *  0.33
                          *  1.1  =  244 GB
