LASTFSS(8)

NAME
lastfss - Hold an ephemeral snapshot for a few hours

SYNOPSIS
lastfss [-U] filesystem backing-dir [ttl]

DESCRIPTION
lastfss creates an ephemeral snapshot for a given filesystem during ttl hours (default is 46 hours). backing-dir is the path to a directory where the snapshot backing store is created.

Unless the -U option is used, the backing store is immedialty deleted on lastfss startup, which means the snapshot is lost if lastfss dies. With the -U option, the backing store is deleted on normal lastfss exit after ttl expiration. This causes backing store to survive machine crashes, but you must clean them up manually in that case.

EXIT STATUS
The lastfss utility exits 0 on success, and 0 if an error occurs.
