simplesnap - 2.1.0 main

simplesnap is a simple way to send ZFS snapshots across a net‐
work. Although it can serve many purposes, its primary goal is
to manage backups from one ZFS filesystem to a backup filesystem
also running ZFS, using incremental backups to minimize network
traffic and disk usage.
.
simplesnap it is designed to perfectly compliment
snapshotting tools, permitting rotating backups with arbitrary
retention periods. It lets multiple machines back up a single
target, lets one machine back up multiple targets, and keeps it
all straight.
.
simplesnap is easy; there is no configuration file needed. One
ZFS property is available to exclude datasets/filesystems. ZFS
datasets are automatically discovered on machines being backed
up.
.
simplesnap is robust in the face of interrupted
transfers, and needs little help to keep running.
.
Unlike many similar tools, simplesnap does not
require full root access to the machines being backed up. It
runs only a small wrapper as root, and the wrapper has only three
commands it implements.
