snapshots in zfs are saved as a dataset under the same zpool that the actual filesystems is on. It is just a point in time snap of the filesystem and only saves the actual changes that happened from the time the snap was taken. If you want to take a backup of you filesystem and mount it us the zfs send and zfs recieve commands. This will create a backup file of your snapshot and then you can import it back into a different zfs filesystem using the zfs recieve command. So something like below will create a filesystem, take a snap of it, then reimport it to a different filesystem.
Code:
zpool create testpool raidz c1t0d0s3 c1t1d0s3 c1t2d0s3 c1t3d0s3
zfs create testpool/test
zfs set mountpoint=/test testpool/test
add data to /test here.......
zfs snapshot testpool/test@testsnap
zfs send testpool/test@testsnap > /tmp/test.snap
zfs receive testpool/newtest < /tmp/test.snap
zfs set mountpoint=/test1 testpool/newtest

I have a oracle instance running in NGZ which is on zfs dataset. Is there any possibility if i can take a zfs snapshot without shutting down the zone and then restore the zfs on other server and start oracle .. will the data be fine or not ? (2 Replies)
With Solaris 11 coming out with a requirement of ZFS on the root disk, I was curious to know who is using the Zeta File System now?
I have been using ZFS for the past year and don't plan to go back to UFS since ZFS is much more reliable and easier to maintain. (13 Replies)
Hi, I am nowusing ZFS since some weeks and now I have 2 questions:
1) in zpool I saw some disk added with the *s2 at the end, I have in mind that should not be ? is this right and if so can I get the *s2 disk out of the zpool ?
2) Zpool has still 2 spare disk but when I try to create a new... (6 Replies)
I have installed Solaris 11 Express on my server and want to set up automatic backuping using zfs snapshots. In the backup script I need to find out the name of the last snapshot of the given filesystem (in order to refer to it as the startpoint of an incremental backup). What is the best way to do...

I am building a new server on sol10_X86.
I am new to ZFS, this will be one of the first systems to use it.
I would like to have /opt /usr and a /u01 as separate file systems from the main ZFS pool. I know that this goes against the basic idea of ZFS, but this is so I can restrict the size/usage... (1 Reply)
Hi,
I need some advice please. I have this server with a couple of zpools, lets call them

amanda-applications - Application-api for amanda
DESCRIPTION
Describe how to use application with Amanda
APPLICATIONS
This section lists the applications included with Amanda. See the individual man pages for instructions on using them. For complete How-To
information, consult the Amanda wiki at http://wiki.zmanda.com.
o amgtar(8), - use GNU Tar to backup and restore data.
o ampgsql(8), - use PostgreSQL's continuous WAL archiving.
o amraw(8), - use open and read to read the data.
o amsamba(8), - use smbclient to backup and restore data.
o amstar(8), - use star to backup and restore data.
o amsuntar(8), - use native tar on Solaris to backup and restore data.
o amzfs-sendrecv(8), - use zfs to create a snapshot and use 'zfs send' to generate the backup.
o amzfs-snapshot(8), - use zfs to create a snapshot and for use with other applications (e.g. amgtar)
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.
