Data Retention Policies

Data generated by the example service falls into a few categories, each with its own retention period. Application logs are kept for 30 days, audit logs for one year, and database backups according to the schedule below.

Data type	Retention period	Storage location
Application logs	30 days	Log aggregation service
Audit logs	1 year	Object storage (archive tier)
Database backups	35 days	Object storage, separate account
Generated documents	7 years	Object storage (archive tier)

Retention changes require review

Any change to a retention period must be reviewed by the platform team, since it may affect both storage cost and compliance obligations.
