The age_to_purge key defines how long quarantine files are stored on your host endpoint before they are removed. Valid values range from 1-365 days. The default aging period is 90 days.
If you define the age_to_purge key manually, you must also define the ProtectionServices enable key manually.
Change this setting using one of the following methods:
Web UI (see Setting the Aging Interval for Quarantine Files ).
API custom configuration channels (see Using API Custom Configuration Channels).
Manually on individual endpoints using a text editor (see Modifying the Configuration File for a Single Endpoint).
For manual changes, the ProtectionServices settings must be enclosed in braces and listed within quotation marks ("). See the example below.
"ProtectionServices": {
"enable": true,
age_to_purge" : 90,
},
