How long sys_audit_delete table keeps track of deleted records and can we restore 1 year back record

[SatyakiBose]

Hello @nikhilsoni973 

ServiceNow keeps 28 days of backup.

When you delete data from your ServiceNow instance, the deletion will take 28 days to be cycled out of a backup of that instance.

Check this article, and they have highlighted it: KB0724183 - A script to automatically clean up sys_audit_delete and sys_audit_relation records

Is there is data on sys_audit_delete; this can be restore. But that is not a fool proof way as not all references and relationships cascade deletions are tracked on this table.
