# Restore from a Backup File

To restore a data index to an Content component, you can send a `DREINITIAL` index action (case sensitive) from your Web browser, including the path to a backup file that you created by using the `DREBACKUP` index action.

TIP: You can also restore Content by using the `RestoreServer` ACI action.

    http://ContentHost:indexPort/DREINITIAL?Path=path

where:

`ContentHost` | is the IP address or host name of the machine on which Content is installed.
`indexPort` | is the Content index port (specified by the `IndexPort` parameter in the `[Server]` section of the Content configuration file).
`path` | is the path to the location of the backup, created by using the `DREBACKUP` index action. In Windows, you can use a Unicode path.

For example:

    http://12.3.4.56:20001/DREINITIAL?Path=E:\DataIndex_Backup

This action uses port `20001` to restore the files backed up on `E:\DataIndex_Backup` to a Content located on a machine with the IP address `12.3.4.56`.

If you create a backup by using the `HostDetails` parameter, you can restore these backups by using the `HostDetails` parameter with your `DREINITIAL`:

    http://ContentHost:port/DREINITIAL?Path=path&HostDetails=True

NOTE: When you restore from a backup by using `DREINITIAL`, Content does not reindex the data.

When you want to update a configuration parameter that requires you to reindex your data, you can use `DREEXPORTIDX` or `DREEXPORTXML` to export an IDX or XML file. You can then initialize your index, make your configuration changes, and index the IDX or XML file back into Content.
