fssnap - create temporary snapshots of a file system


/usr/sbin/fssnap [ -F FSType ] [ -V ] -o special_options [ mount-point | special ] /usr/sbin/fssnap -d [ -F FSType ] [ -V ] -o special_options [ mount-point | special ] /usr/sbin/fssnap -i [ -F FSType ] [ -V ] -o special_options [ mount-point | special ]


The fssnap command creates a stable, read-only snapshot of a file system when given either an active mount point or a special device containing a mounted file system, as in the first form of the synopsis. A snapshot is a temporary image of a file system intended for backup operations. A path to the virtual device that contains this snapshot is printed to standard output when a snapshot is created.


The following options are supported: -d Deletes the snapshot associated with the given file system. -F FSType Specifies the file system type to be used. The FSType should either be specified here or be determined by matching the block special device with an entry in the /etc/vfstab table, or by consulting /etc/default/fs. -i Displays the state of any given FSType snapshot. If a mount-point or device is not given, a list of all snapshots on the system is displayed. When a mount- point or device is specified, detailed information is provided for the specified file system snapshot by default. The format and meaning of this information is file-system dependent. See the FSType-specific fssnap man page for details. -o special_options See the FSType-specific man page for fssnap. -V Echoes the complete command line, but does not execute the command.
