DESCRIPTION

ZnapZend is a snapshot based zfs backup daemon creating snapshots on a scheduled basis on the source filesystem and on destination filesystems.

ZnapZend reads its configuration from custom properties in the fileset. Use znapzendzetup to set these properties.

-d, --debug

talk a lot while running. Sends debug messages to stderr.

-n, --noaction

don't do any actions which have lasting effect. Ideal to try our new new configurations together with --debug

--nodestroy

do all changes to the filesystem except destroy old snapshots

--logto={syslog::facility|filepath}

send logs out to either syslog or a logfile. Default is to send logs to syslog::daemon when runing daemonized. When running in debug mode, the logs will go to STDERR by default.

Examples:

--logto=/var/log/znapzend.log
--logto=syslog::daemon
--loglevel={debug|info|warning|err|alert}

Define the log level when logging to file. Default is debug.

--pidfile=path

write a pid file when running in daemon mode

--daemonize

Fork into the background.

--runonce=fileset

run one round on source fileset. This is very useful for testing. Use it in connection with --noaction and --debug while testing your new configuration

EXAMPLE

To test a new config

znapzend --debug --noaction --runonce=tank/test

To run as a daemon

znapzend --daemonize --pidfile=/var/run/znapzend.pid --logto=syslog::daemon
