Solaris backup machine
Hi,

I have a server with Solaris 11 with a zpool raid to serve as a NAS. Every day in the morning I do an incremental snapshot of the zpool and send it to another local disk as a backup.

I would now like to build another small server to hold backups in a different place to prevent data loss due to e.g. fire, robery, aso. I would send there incremental backup snapshots once a week over internet.

Would you please help me choose HW for this backup machine? Follows a list of criteria:

* the hw should be minimalistic (I will put it in a small metal box),
* there should be no need for active cooling,
* the performance of the system can be minimal (it will only be used to recieve and store backups),
* it should support my 3TB SATA III HD (IntelliPower, WD30EZRX).

Thanks in advance!
Dusan

amzfs-sendrecv

AMZFS-SENDRECV(8)					  System Administration Commands					 AMZFS-SENDRECV(8)

NAME

       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"
	}
