Back up the Entire IDOL Content component Data Index

You can back up the entire IDOL Content component data index in several ways:

Back up the Data Index Immediately

Send a DREBACKUP action (case sensitive) from your Web browser to copy all the IDOL Content component data index *.DB files to a new location.




is the IP address or host name of the Content machine.


is the Content index port (specified by the IndexPort parameter in the [Server] section of the Content configuration file).


is the path to the location where you want to create the backup. In Windows, you can use a Unicode path.

For example:


This action uses port 20001 to create a backup of the Content data index on E:\Backup. The Content whose data index is backed up is located on a machine with the host name MyHost.

You can set the optional parameter CheckIndexUpdates to True if you want to check for updates to the index since the last backup. In this case, Content skips the backup if the index has not been modified.

DREBACKUP also accepts the optional parameter HostDetails. Set HostDetails to True to write the backup to a subdirectory in the specified directory path. Content names this directory using its host and port. In this way, a series of servers under a Distributed Index Handler (DIH) can all accept the same directory as input, and they write to a subdirectory named with their own host and port.

Back up the Data Index at Regular Intervals

Use the following procedure to back up the data index at regular intervals.

Back up the Data Index Automatically

Use the following procedure to back up the data index automatically whenever you send a DRECOMPACT action.

Back up the Data Index Dynamically

If your IDOL Content component storage is a SAN with disk-snapshot capabilities, you can perform a hot backup (snapshot) of the data index.
