The Salesforce App excludes certain Salesforce components by default from the backup. This article lists those components so that you can plan and configure your backup definitions to either include or skip these components from the backup.
The following sections are divided as per the component type.
- Default Sandbox Populated Objects
- Excluded Object Extensions
- Default Excluded Objects
- System Excluded Objects
- Default Excluded Global Fields
- Default Excluded Fields
Default Sandbox Populated Objects
A Sandbox creation or refresh process copies certain objects automatically in the Salesforce environment by default.
The Salesforce App excludes these objects during a backup. Here's a list of sandbox populated objects for your reference:
ApexClass ApexPage ApexTrigger ContentDistribution DuplicateRecordItem FieldPermissions Folder Group IDEWorkspace NewsFeed Note ObjectPermissions Organization OrgWideEmailAddress PermissionSet Pricebook2 PricebookEntry Product2 Profile RecordType Scontrol StaticResource TopicAssignment TraceFlag User UserLicense UserProfileFeed UserRole
Excluded Object Extensions
In Salesforce, certain objects are read-only. These objects are excluded from backup as it requires additional processing for the following reasons:
- Calculate Sharing Rules
- Lookup objects, such as __kav.object and __feed.object whose data is actually stored in a different object
- Unable to use standard SOQL queries or SOAP API to query
- Object is inaccessible
Here's a list of object extensions for your reference:
History Share Tag Chatter Feed ViewStat VoteStat ChangeEvent __e __x __xo __mdt __hd
Default Excluded Objects
A Sandbox refresh process copies Salesforce system objects and read-only metadata objects by default. To modify permissions for read-only metadata objects, use the Salesforce Metadata API. For more information, see Modify Metadata through Metadata API.
For example, during Sandbox creation, Salesforce copies Custom Settings and other Standard Objects containing Settings data. Salesforce also copies the metadata-related objects, such as ApexClass and ApexTrigger. Hence, the Salesforce App excludes these system objects by default from the backup.
The following table explains the reason for certain object exclusions.
