FFS - Fast
File scanning is
Conventional file scanning using
standard OS APIs is limited to 1-2K file/sec or less. Scanning
large servers using conventional methods
would take over 24 hours,
incremental backups and generating SRM reports is impractical.
Conventional file scanning is a very resource
intensive operation, which can significantly slow down other activities
on the server.
solution is provided by Microtal’s Fast File Scanner (FFS).
proprietary technology for scanning filesystems at rates 10-50 times
faster than conventional methods while requiring significantly less CPU
and disk resources. FFS stores filesystem metadata in special database
files called FSDB files, which are very compact and efficient.

All other filesystems are scanned using the standard scanner. Both
scanners generate the same output and the selection of the actual
scanner (standard vs. fast) is transparent to the user.
