Command-line utility for wiping unallocated space on a filesystem
The zeroer utility can be used to wipe empty space on a disk. In contrary to dd,
zeroer does not wipe existing files on a partition. It overwrites the
unallocated disk space around existing files, which means that deleted files
cannot be restored after processing a certain partition with zeroer.
The utility's principle consists in writing huge zero-padded memory blocks to a
file. To a certain extent this works similar to dd, however zeroer dynamically
reduces the blockwriter's buffer size when the filesystem is going to be full.
Zetaback ZFS backup and recovery management system
Zetaback ZFS backup and recovery management system.
Zetaback is a thin-agent based ZFS backup tool. It is designed to:
* run from a central host
* scan clients for new ZFS filesystems
* manage varying desired backup intervals (per host) for
o full backups
o incremental backups
* maintain varying retention policies (per host)
* summarize existing backups
* restore any host:fs backup at any point in time to any target host

Simple way of maintaining zfs snapshots using the periodic system
Scripts that uses the periodic system to create and manage zfs
snapshots. Easily configured via /etc/periodic.conf
ZFS Snapshot Replication Script
zfs-replicate makes migrating a few filesystems and many
snapshots to a new zpool more easier.
Automatic ZFS snapshot management tool
A simple ruby script for automating creation and removal of ZFS snapshots.
Display human-readable ZFS statistics
zfs-stats displays ZFS statistics in human-readable format including
ARC, L2ARC, zfetch (DMU) and vdev cache statistics.
This script is a fork of Jason J. Hellenthal's <jhell@DataIX.net>

Simple sh script to make zfs rolling snaphosts with cron
zfSnap is a simple sh script for creating ZFS snapshots. When called from
cron rolling snapshots can be created and deleted automatically. The main
advantage of zfSnap is that it is written in 100% pure /bin/sh, does not
require any additional software to run, and is simple to use.
zfSnap keeps all information about snapshot in snapshot name. zfs snapshot
names are in form: Timestamp--TTL where timestamp is date and time of
snapshot creation and TTL is Time To Live in human readable form.
Portable performant script to make rolling ZFS snapshots easy
zfsnap makes rolling ZFS snapshots easy and - with cron - automatic.
The main advantages of zfsnap are its portability, simplicity, and performance.
It is written purely in /bin/sh and does not require any additional software -
other than a few core *nix utilies.
zfsnap stores all the information it needs about a snapshot directly in its
name; no database or special ZFS properties are needed. The information is
stored in a way that is human readable, making it much easier for a sysadmin to
manage and audit backup schedules.
Snapshot names are in the format of pool/fs@[prefix]Timestamp--TimeToLive
(e.g. pool/fs@weekly-2014-04-07_05.30.00--6m). The prefix is optional but can
be quite useful for filtering, Timestamp is the date and time when the snapshot
was created, and TimeToLive (TTL) is the amount of time the snapshot will be
kept until it can be deleted.
OpenSolaris-compatible auto snapshotting for ZFS
ZFSTools is an OpenSolaris-like and compatible auto snapshotting
script, which also supports auto snapshotting mysql databases.
File corruption detection and repair program
ZIDRAV is a file corruption detection and repair program. It's designed
to provide a way to fix file damage without having to redownload the
entire (potentially large) file over a (potentially slow) connection.
