You can take a snapshot of an entire pool and all file systems included:
From "man zfs" (Solaris 11, though):

Snapshots
A snapshot is a read-only copy of a file system or volume.
Snapshots can be created extremely quickly, and initially
consume no additional space within the pool. As data within
the active dataset changes, the snapshot consumes more data
than would otherwise be shared with the active dataset.
Snapshots can have arbitrary names. Snapshots of volumes can
be cloned or rolled back, but cannot be accessed indepen-
dently.
File system snapshots can be accessed under the
".zfs/snapshot" directory in the root of the file system.
Snapshots are automatically mounted on demand and may be
unmounted at regular intervals. The visibility of the ".zfs"
directory can be controlled by the "snapdir" property.
Creates a snapshot with the given name. See the
"Snapshots" section for details.
-r
Recursively create snapshots of all descendent
datasets. Snapshots are taken atomically, so that
all recursive snapshots correspond to the same
moment in time.
-o property=value
Sets the specified property; see "zfs create" for
details.

amzfs-snapshot - Amanda script to create zfs snapshot
DESCRIPTION
amzfs-snapshot is an Amanda script implementing the Script API. It should not be run by users directly. It create a zfs snapshot of the
filesystem where the path specified is mounted.
PRE-DLE-* create a snapshot and the POST-DLE-* destroy the snapshot, *-DLE-AMCHECK, *-DLE-ESTIMATE and *-DLE-BACKUP must be set to be
executed on the client:
execute-on pre-dle-amcheck, post-dle-amcheck, pre-dle-estimate, post-dle-estimate, pre-dle-backup, post-dle-backup
execute-where client
The PRE_DLE_* script output a DIRECTORY property telling where the directory is located in the snapshot. The application must be able to
use the DIRECTORY property, amgtar can do it.
The script is run as the amanda user, it must have the priviledge to create and destroy snapshot:
zfs allow -ldu AMANDA_USER mount,snapshot,destroy FILESYSTEM
Some system doesn't have "zfs allow", but you can give the Amanda backup user the rights to manipulate ZFS filesystems by using the
following command:
usermod -P "ZFS File System Management,ZFS Storage Management" AMANDA_USER
This will require that your run zfs under pfexec, set the PFEXEC property to YES.
The format of the DLE must be one of:
Desciption Example
-----------------
Mountpoint /data
Arbitrary mounted dir /data/interesting_dir
ZFS pool name datapool
ZFS filesystem datapool/database
ZFS logical volume datapool/dbvol
The filesystem must be mounted.
PROPERTIES
This section lists the properties that control amzfs-snapshot's functionality. See amanda-scripts(7) for information on the Script API,
script configuration.
DF-PATH
Path to the 'df' binary, search in $PATH by default.
ZFS-PATH
Path to the 'zfs' binary, search in $PATH by default.
PFEXEC-PATH
Path to the 'pfexec' binary, search in $PATH by default.
PFEXEC
If "NO" (the default), pfexec is not used, if set to "YES" then pfexec is used.
EXAMPLE
In this example, a dumptype is defined to use amzfs-snapshot script to create a snapshot and use amgtar to backup the snapshot.
define script-tool amzfs_snapshot {
comment "backup of zfs snapshot"
plugin "amzfs-snapshot"
execute-on pre-dle-amcheck, post-dle-amcheck, pre-dle-estimate, post-dle-estimate, pre-dle-backup, post-dle-backup
execute-where client
#property "DF-PATH" "/usr/sbin/df"
#property "ZFS-PATH" "/usr/sbin/zfs"
#property "PFEXEC-PATH" "/usr/sbin/pfexec"
#property "PFEXEC" "NO"
}
define dumptype user-zfs-amgtar {
dt_amgtar
script "amzfs_snapshot"
}
