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.
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 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.
