The snapshot is a PIT copy of all the data in the ZFS, the new device can be an other ZFS that you created.
The ZFS snapshot will grow - quickly if there is a lot of write activity, but the send and recieve operation will send an exact copy of the required data to the new location.
If the customer has a big down on the key exchange then use the following;
Hello,
Our RAID and server recently crashed and we are trying to recover our data. The problem appears to be that the Veritas File System/Logical Volume Manger became corrupt on our RAID. We are down to our last option, which is to run some Veritas commands that "may" result in data loss.

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 need some advice please. I have this server with a couple of zpools, lets call them

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"
}
