## About
Znsap script handles ZFS on linux snapshot functionnality, creates and handles a defined number of snapshots in Samba VFS friendly format (Windows previous versions support).
It will send an alert mail if any snapshot related functionnality creates an error.
## Installation
You can download the latest stable version of znsap directly on authors website or grab the latest working copy on git.
$ git://github.com/deajan/zsnap.git
$ chmod +x zsnap.sh
Additionnaly, you may copy zsnap.sh to /usr/local/bin
$ cp zsnap.sh /usr/local/bin
Once you have a copy of Zsnap, edit the configuration file to match your needs and you're ready to run.
## Usage
$ zsnap.sh /path/to/your.conf status
$ zsnap.sh /path/to/your.conf create
You may run multiple instances of zsnap by creating mutliple configuration files, one per dataset.
You can easily add zsnap as cron task which will take snapshots at a given time. Use parameter --silent to prevent writing to stdout for crontasks.
$ ./zsnap.sh /path/to/your.conf create --silent
The number of kept snapshots is handled by zsnap, but you may also control it's behaviour manually by using the following commands:
$ ./zsnap.sh /path/to/dataset.conf destroyoldest
$ ./zsnap.sh /another/path/other_dataset.conf destroyall
You may increase output level of zsnap script by adding parameter --verbose to see what is actually going on
$ ./zsnap.sh /my/conf/files/my.conf create --verbose
Zsnap will mount every snapshot in Samba's VFS object shadow_copy friendly format. Keep in mind that samba's VFS object only works if you share the root of your ZFS dataset or subdataset.
