Clone results based on Exclusion and Preserver configurationDescription Clones will read exclude/preserver lists from the source instance during the early stage of the clone. If updates are made to the exclusion/preserver list before clone, the clone will honor it even if the clone does not take on-demand backup. This article explains through six different scenarios the expected results of the data in a table based on the configuration of the Table Exclusion and Data Preserver when performing a clone. Release or EnvironmentAllResolution Test parameters used: source = clone source (ex. production instance)target = clone target (ex. test instance)sys_temp = custom table we will be preserving and excluding dataData Preservers are always setup on source under System Clone > Preserver DataTable Exclusions are always setup on source under System Clone > Exclude DataDefault clone settings used as per screenshot: IMPORTANT: If 'Exclude audit and log data' is not checked, the list of table exclusions under 'Exclude Data' is ignored! (see KB0751430) Scenario #1 Table Exclusion: NoneData Preserver: None Table Exclusion on source Data Preserver on source Results #1 All records in sys_temp table on target are deleted.All records in sys_temp table on source are copied to sys_temp table on target. Data on source Data on target before clone Data on target after clone Scenario #2 Table Exclusion: NoneData Preserver: Yes, plus 'Conditions' field is empty. Table Exclusion on source Data Preserver on source Results #2: All records in sys_temp table on target are preserved.Records in sys_temp table on source, which do not exist in sys_temp table on target (based on sys_id), are copied to sys_temp table on target. Data on source Data on target before clone Data on target after clone Scenario #3 Table Exclusion: NoneData Preserver: Yes, plus 'Conditions' field contains a value. Table Exclusion on source Data Preserver on source Results #3 Records in sys_temp table on target, found by Data Preserver, are preserved.Records in sys_temp table on target, not found by Data Preserver, are deleted.Records in sys_temp table on source, which do not exist in sys_temp table on target (based on sys_id), are copied to sys_temp table on target. Data on source Data on target before clone Data on target after clone Scenario #4 Table Exclusion: YesData Preserver: Yes, plus 'Conditions' field is empty. Table Exclusion on source Data Preserver on source Results #4: All records in sys_temp table on target are preserved.No records are copied over from sys_temp table on source. Data on source Data on target before clone Data on target after clone Scenario #5 Table Exclusion: YesData Preserver: Yes, plus 'Conditions' field contains a value. Table Exclusion on source Data Preserver on source Results #5 Records in sys_temp table on target, found by Data Preserver, are preserved.Records in sys_temp table on target, not found by Data Preserver, are deleted.No records are copied over from sys_temp table on source. Data on source Data on target before clone Data on target after clone Scenario #6 Table Exclusion: YesData Preserver: None Table Exclusion on source Data Preserver on source Results #6 All records are deleted from sys_temp table on target. No records are copied over from sys_temp table on source.
