About File Change Log

The VxFS File Change Log (FCL) tracks changes to files and directories in a file

system.

Applications that typically use the FCL are usually required to:

■ scan an entire file system or a subset

■ discover changes since the last scan

These applications may include: backup utilities, webcrawlers, search engines,

and replication programs.

Note: The FCL tracks when the data has changed and records the change type,

but does not track the actual data changes. It is the responsibility of the application

to examine the files to determine the changed data.

FCL functionality is a separately licensable feature.

See the Veritas Storage Foundation Release Notes.
