Some data protection types are missing from reports or summaries
The data protection history or CommCell Events may have been pruned from the CommNet Server
The retention of data protection history and CommCell Events is based on the settings for pruning in the CommNet Properties dialog box. Once data has been pruned from the CommNet Server, it is no longer available for reports.
Additionally, since the software receives historical data from the CommCell when first installed, only the history that is stored on the CommCell at that time will be available for reports. For example, if your pruning schedule is set for 12 months, but the CommCell only has 2 months of historical data available when you first install the software, you will only be able to run reports for the previous 2 months. As time goes on, while the CommCell will continue to prune according to its schedule, historical job and event data will continue to accumulate until the time limit for CommNet Server pruning is reached.
Synthetic full backups are not considered when checking coverage and are not considered in Q-Factor calculations
Because synthetic full backups are produced by combining previous data protection operations, only the original data protection operations are counted as coverage for the days when they actually ran. For example, if an incremental backup was executed on Monday, May 1st, and a synthetic full backup was executed on Tuesday, May 2nd; a Data Protection Coverage Report run on Wednesday, May 3rd, which is checking coverage for the past three days, would only show coverage for Monday, May 1st because that was the only day that a data protection operation was executed. The synthetic full backup that was executed on Tuesday would not be counted as coverage.
When users run a Data Protection Coverage Report, the report will include all data protection operations, including synthetic full backups. |
