File System Discovery Task Wizard

File System Discovery Task Wizard - Advanced

Administrator Help | TRITON AP-DATA | Version 8.3.x

Select this option if you do not want to limit the bandwidth used for the discovery process.

Select this option if want to limit the bandwidth used for the discovery process to an average number of megabytes per second, then select the desired limit.

This option does not control the network bandwidth per file. Large files might still consume the available network bandwidth for short periods of time.

The option does, however, prevent strain on your file servers, network adapters, and on the TRITON AP-DATA system.

While planning to use this feature, keep in mind the following:

Each file will be downloaded as fast as the operating system will allow.

Subsequent file operations can be paused to maintain average bandwidth utilization.

Average bandwidth utilization is maintained across several file operations, not during single file operation.

In addition, if the amount of data for discovery is big, consider placing the supplemental server with the crawler and policy engine closer to your data sources. This eliminates the need to copy large volumes of data across WAN links.

Windows QoS can be configured to maintain throttling on a network level.

Full scan schedule

Select one of the following options to indicate when you want to perform full discovery scans:

Only on policy update - Select this option if you want to perform full discovery only when a discovery policy changes.

On policy update or fingerprinting version update - Select this option if you want to perform full discovery when a discovery policy or a fingerprinting version changes.

Always - Select this option if you want to perform full discovery on the scheduled time no matter what has changed. (We don't recommend choosing "always," because this slows the discovery process and taxes the system and file servers.)

File access timestamp

Select Preserve original access time if do not want file access timestamps to be updated when files are scanned by Data Security. When this option is selected, the operating system controls the "Last Accessed" timestamp of scanned files.

Note:

To preserve access time, you must give Data Security read-write privileges for all hosts where discovery is being performed.
