# DREFLUSHANDPAUSE

Prepares IDOL Server for a snapshot (hot backup). IDOL Server flushes all files to disk and pauses indexing, so a snapshot of the data can be taken. This index action is most applicable if your IDOL storage is a SAN with disk-snapshot capabilities.

Note: The index ID returned from this index action (for example, `INDEXID=41`) because you need this ID to restart the paused indexing queue.

After sending the index action, poll IDOL Server with the IndexerGetStatus action until the returned status is `-16` (Indexing Paused). You can then perform the snapshot.

After the hot backup completes, restart the index queue, again with the IndexerGetStatus action and with the index ID returned from `DREFLUSHANDPAUSE`. For example:

    http://Hume:20000/action=IndexerGetStatus&index=41&IndexAction=restart

## Example

    http://Hume:20001/DREFLUSHANDPAUSE?

This index action uses port `20001` to instruct the Distributed Index Handler on host `Hume` to flush all files to disk and pause indexing.

## Parameters

Parameter | Description | Required
--- | --- | ---
IgnoreMaxPendingItems | Whether to ignore the IndexQueueMaxPendingItems limit for this index action. |
IndexUID | An identification code for any document tracking events. |
Priority | The priority for the index job. |
