You should be able to create a mirror with from existing two disks to new two disks using attach.
You can try this method on your server using ZVOL's or files as backend for your test zpool.
First create a pool with two zvols or files as backend device, then use attach to attach additional 2 zvols/files as backend device.
This can be 200 MB files or zvols, no need for gigabytes, on existing free space anywhere on the system.
If everything is ok, you can run it on your real data.
Also, you can use virtualization on your desktop to check if things work before typing it on production systems.
Hope that helps

Hello All
I’ve made the decision to switch my storage server from FreeNAS to Solaris. I opted to use FreeNAS as it has ZFS and until BTRFS is stable, it’s the best option (IMHO) for backup and network storage.

APPLICATIONS
This section lists the applications included with Amanda. See the individual man pages for instructions on using them. For complete How-To

DEFINING APPLICATIONS
An application is defined in amanda.conf(5) as follows:
define application-tool $appconfigname {
plugin "$pluginname"
property "$PROPERTY_NAME" "$PROPERTY_VALUE"
...
}
and then referenced in a dumptype as
define dumptype $dumptypename {
...
program "APPLICATION"
application "$appconfigname"
}
Application properties, like Amanda configuration parameters, are insensitive to case, and - (dash) and _ (underscore) may be used
interchangeably.
See the individual plugin documentation for properties applicable to each plugin.
