ZnapZend is a ZFS centric backup tool. It relies on snapshot, send and receive todo its work. It has the built-in ability to manage both local snapshots as well as remote copies by thining them out as time progresses.
The ZnapZend configuration is stored as properties in the ZFS filesystem itself.
Follow these zimple inztructionz below to get a custom made copy of znapzend. Yes you need a compiler and stuff for this to work.
On RedHat you get the necessaries with:
yum install perl-core
On Ubuntu / Debian with:
apt-get install perl
On Solaris you may need the c compiler from Solaris Studio and gnu-make since the installed perl version is probably very old.
On OmniOS/SmartOS you will need perl and gnu-make
with that in place you can now utter:
wget https://github.com/oetiker/znapzend/releases/download/v0.16.0/znapzend-0.16.0.tar.gz
tar zxvf znapzend-0.16.0.tar.gz
cd znapzend-0.16.0
./configure --prefix=/opt/znapzend-0.16.0
If configure finds anything noteworthy, it will tell you about it. If any perl modules are found to be missing, they get installed locally into the znapzend installation. Your perl installation will not get modified!
make
make install
Optionally (but recommended) put symbolic links to the installed binaries in the system PATH.
for x in /opt/znapzend-0.16.0/bin/*; do ln -s $x /usr/local/bin; done
Debian control files, guide on using them and experimental debian packages can be found at https://github.com/Gregy/znapzend-debian
Use the znapzendzetup program to define your backup settings. For remote backup, znapzend uses ssh. Make sure to configure password free login for ssh to the backup target host.
The znapzend demon is responsible for doing the actual backups.
To see if your configuration is any good, run znapzend in noaction mode first.
znapzend --noaction --debug
If you don't want to wait for the scheduler to actually schedule work, you can also force immediate action by calling
znapzend --noaction --debug --runonce=<src_dataset>
then when you are happy with what you got, start it in daemon mode.
znapzend --daemonize
Best is to integrate znapzend into your system startup sequence, but you can also run it by hand. See the init/README.md for some inspiration.
If you want to know how much space your backups are using, try the znapzendztatz utility.
If you find a problem with znapzend, please open an Issue on GitHub.
