Tools for periodic and manual management of UFS2 snapshots
snap is a tool for the management of UFS2 snapshots created by mount8. It can maintain hourly, daily and weekly snap- shots while trying to minimize the disk space occupied. The snapshots created are labeled with their creation time, and users can create them manually.
The major advantage over sysutils/freebsd-snapshot is that it uses hardlink to save diskspace, mark each snapshot with its creation time and calculates redundancy in a smart way.
