Abstract

Several operating systems support the ability to mount file systems within file systems to make directories and files available for use at a particular location. Disclosed is a method that handles mount points that are encountered while performing a file backup operation against a file system.

Technique to Handle Mounted File Systems within File Systems

      Several operating systems support the ability to mount file
systems within file systems to make directories and files available
for use at a particular location.  Disclosed is a method that handles
mount points that are encountered while performing a file backup
operation against a file system.

      In a distributed, multiple workstation, client/server based
backup and restore system, it is advantageous to drive the backup
processing from the file system perspective.  When backup processing
is being performed, the file system is scanned to determine which
files and directories should be backed up to an Archive Server
(backup data repository).  During this scanning process, it is
possible to encounter a mount point, a directory or file at which a
new file system, directory, or file is made accessible.

      The invention disclosed here is to ignore mount points
encountered during a file system scan.  This technique allows control
over backup frequency of file systems to remain at the file system
level.
