-## Log retention
-
-By default, data and logs for task runs in a registry are retained for 30 days. After that time, records are automatically purged. 
-
-If you want Azure Container Registry to archive the data for a task run, enable archiving using the [az acr task update-run](/cli/azure/acr/task#az-acr-task-update-run) command. The following example enables archiving for the task run *cf4*:
-
-```azurecli
-az acr task update-run \
-  --registry mycontainerregistry1220 \
-  --run-id cf4 --no-archive false
-```
-
 ## Alternative log storage
 
 You might want to store task run logs on a local file system or use an alternative archiving solution such as Azure Storage.
