System Administration Commands fssnap(8)
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 sys‐
tem 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 cor‐
rupted files. It is a good idea to ensure active applications are sus‐
pended or checkpointed and their associated files are also consistent
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 mean‐
ing 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.
