This page resumes other projects, among zsnap (zfs snapshot handling script), a collection of useful windows and linux scripts.
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.
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.
$ 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.
