Reference topics provide information about system properties and data limits.
* **[Archive rule and destroy rule properties](https://servicenow-prod.fluidtopics.net/T29H7BHOrh9kx7RpDbcuew)**   
  Rules to prevent the archive process from consuming too many system resources have been automated. You can manually change the system behavior.
* **[Data archive table size limits](https://servicenow-prod.fluidtopics.net/gm5OK3sb~FilUO8DnTeGbg)**   
  There are constraints to the size of the table you use to archive your instance data.
* **[Table cleaner properties](https://servicenow-prod.fluidtopics.net/bc5i6do7aHB2YVYK18hftQ)**   
  These system properties control table cleaner behavior.
* **[Unique record identifier (sys_id)](https://servicenow-prod.fluidtopics.net/uPAKWbHDiI~Pagf56dbUGw#c_UniqueRecordIdentifier)**   
  A unique 32-character GUID (Globally Unique ID), called a Sys ID (sys_id) identifies each record in an instance.
* **[Domain separation and Data Management](https://servicenow-prod.fluidtopics.net/YAkQRtq50eMYFz6_NKXw5g)**   
  Domain separation is supported in Data Management. Domain separation enables you to separate data, processes, and administrative tasks into logical groupings called domains. You can control several aspects of this separation, including which users can see and access data.
