NAME
fssnap - create temporary snapshots of a file system
SYNOPSIS
fssnap [-F FSType] [-V] -o special_options /mount/point
fssnap -d [-F FSType] [-V] /mount/point | dev
fssnap -i [-F FSType] [-V] [-o special_options] [/mount/point | dev]
DESCRIPTION
The fssnap command creates a stable, read-only snapshot of a file system when given either an active mount point or a special device con-
taining 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.
While the snapshot file system is stable and consistent, an application updating files when the snapshot is created might leave these files
in an internally inconsistent, truncated, or otherwise unusable state. In such a case, the snapshot will contain these partially written or
corrupted files. It is a good idea to ensure active applications are suspended or checkpointed and their associated files are also consis-
tent during snapshot creation.
File access times are not updated while the snapshot is being created.
A path to the virtual device that contains this snapshot is printed to standard output when a snapshot is created.
OPTIONS
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.
OPERANDS
The following operands are supported:
/mount/point The directory where the file system resides.
EXAMPLES
See FSType-specific man pages for examples.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
FILES
/etc/vfstab Specifies file system type.
/etc/default/fs Specifies the default local file system type.
