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.
