This blog describes Time Slider, a new feature in OpenSolaris 2008.11. Time slider provides an automatic way to backup your data on the same disc using one of Sun's ZFS file system's unique features, snapshots. With Time Slider, you can browse and recover files from snapshot backups using the GNOME file manager.
I created a zpool and in it there is a zfs volume. I used that to backup data on another server using ISCSI. Now I have the data and want to take a snapshot so that I can view it on another machine that is not in production.
Here is what I have done
# zfs snapshot mat/vol_1@snap1
# zfs list -t... (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...

Hi, I deleted a zfs snapshot because it was as big as the original zfs. After the snapshot was removed, all the data in the original zfs is gone. How this happened? Can I restore the snapshot? Please help. Thanks a lot! (5 Replies)
I saved one of my zfs snapshot on the remote machine with following command. And now i want to restore the same snapshot to original server how can i receive it on the original server from backup server.

Hi,
I am working on Network Management Software product. This is supported both windows and solaris platform. I need to take the snapshot of the solaris server ( which installed our product), like vmware in windows.

amzfs-sendrecv - Amanda script to create zfs sendrecv
DESCRIPTION
amzfs-sendrecv is an Amanda application implementing the Application API. It should not be run by users directly. It create a zfs snapshot
of the filesystem and backup the snapshot with 'zfs send'. Snapshot are kept after the backup is done, this increase the disk space use on
the client but it is neccesary to be able do to incremental backup. If you want only full backup, you can disable this feature by setting
the KEEP-SNAPSHOT property to 'NO'. Only the restoration of the complete backup is allowed, it is impossible to restore a single file.
The application is run as the amanda user, it must have many zfs priviledge:
zfs allow -ldu AMANDA_USER mount,create,rename,snapshot,destroy,send,receive 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 diskdevice in the disklist (DLE) must be one of:
Desciption Example
-----------------
Mountpoint /data
ZFS pool name datapool
ZFS filesystem datapool/database
ZFS logical volume datapool/dbvol
The filesystem doesn't need to be mounted.
PROPERTIES
This section lists the properties that control amzfs-sendrecv's functionality. See amanda-applications(7) for information on the
Application API, application configuration.
DF-PATH
Path to the 'df' binary, search in $PATH by default.
KEEP-SNAPSHOT
If "YES" (the default), snapshot are kept after the backup, if set to "NO" then snapshot are no kept and incremental backup will fail.
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-sendrecv application to backup a zfs filesystem.
define application-tool amzfs_sendrecv {
comment "amzfs-sendrecv"
plugin "amzfs-sendrecv"
#property "DF-PATH" "/usr/sbin/df"
#property "KEEP-SNAPSHOT" "YES"
#property "ZFS-PATH" "/usr/sbin/zfs"
#property "PFEXEC-PATH" "/usr/sbin/pfexec"
#property "PFEXEC" "NO"
}
define dumptype user-zfs-sendrecv {
program "APPLICATAION"
application "amzfs_sendrecv"
}
