# HostDetails

Whether the backup must use a directory based on a specific `host` and `port` combination.

Set `HostDetails` to `true` to write the backup to a sub-directory in the specified directory path, which is named using the IDOL Server host and port. In this way, a series of child servers under a Distributed Index Handler (DIH) can all accept the same directory as input, without overwriting the backup of another server.

For example:

If sending a DREBACKUP index action to a DIH on the `localhost` using index port 12611, you use the following index action:

    http://localhost:12611/DREBACKUP?X:\backup\&HostDetails=true

This DIH then distributes the following index action to each of its `N` child servers:

    http://serverhostN:serverIndexportN/DREBACKUP?X:\backup\&HostDetails=true

Where `serverhostN` is the host name for child server `N`, and `serverIndexportN` is its Index port. The child servers then write the backup to the following directory:

    X:\backup\serverhostN-serverACIPORTN

Where, again, `serverhostN` is the host name for child server `N`, and where `serverACIPORTN` is its ACI port. In this way, even if `X:\backup` is a location shared between all the child servers, they each write a separate location, as they each have a different host and port combination.
