ZnapZend is a ZFS centric backup tool. It relies on snapshot, send and receive todo its work. It has the built-in ability to 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.
To zetup znapzend follow these zimple inztructionz
wget https://github.com/oetiker/znapzend/releases/download/v0.8.6/znapzend-0.8.6.tar.gz
tar zxvf znapzend-0.8.6.tar.gz
cd znapzend-0.8.6
./configure --prefix=/opt/znapzend-0.8.6if configure complains about missing perl modules, run
./setup/build-thirdparty.sh /opt/znapzend-0.8.6/thirdpartyto install the missing modules into the specified directry. This will NOT messup your local perl installation!
Now you can run configure again and then
make installUse 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.
/opt/znapzend-0.8.6/bin/znapzend --noaction --debugIf you don't want to wait for the scheduler to actually schedule work, you can also force immediate action by calling
/opt/znapzend-0.8.6/bin/znapzend --noaction --debug --runonce=<src_dataset>then when you are happy with what you got, start it in daemon mode.
/opt/znapzend-0.8.6/bin/znapzend --daemonizeBest is to integrate znapzend into your system startup sequence, but you can also run it by hand.
For illumos OSes you can import the znapzend service manifest provided in the install directory:
svccfg validate /opt/znapzend-0.8.6/init/znapzend.xml
svccfg import /opt/znapzend-0.8.6/init/znapzend.xmland then enable the service
svcadm enable oep/znapzendIf you want to know how much space your backups are using, try the znapzendztatz utility.
Enjoy!
