Select the number of snapshots to keep
Select from the following options to control the number of reports that are kept in report history. Report history settings can vary for each report.
Select Use default setting to retain the default setting. The report server administrator controls a master setting for report history storage. If you choose this option, the number of snapshots that are retained is obtained from this master setting.
Select Keep an unlimited number of snapshots in report history to retain all report history snapshots. You must manually delete snapshots to reduce the size of report history.
Select Limit the copies of report history to retain a set number of snapshots. When the limit is reached, older copies are removed from report history to make room for newer copies.
Report history is stored in the report server database. If you have large reports or numerous reports for which you want to maintain history, consider limiting the amount of report history to help manage the disk space requirements of the report server database.
