www.netapp.com上的product里有FAS270的specification的PDF文档，你可以参考一下，上面有直连时支持的磁带库的信息，如果还要备份软件的话NBU就可以啊，而且还不用考虑FAS270支持的那些磁带库了，NBU支持的就都能用。

NBU贵啊……

backup fas270's snapshot? good idea, but implement difficult . I guess hehe.
btw
celerra can create snapshot and celerra supports virus scan integrating with norton.

那就直连不要NBU了啊，楼上啊，备份SNAPSHOT有什么难实现的啊？

I just do not know how to backup a snapshot of LUN
PLS give me some idea

滋毛儿

Backing up a single LUN to tape   

To map a LUN within a snapshot to the backup server for backup, the snapshot must be made writable.

To map a LUN within a snapshot for backup, complete the following steps.

Step

1 Enter the following command to create an igroup:

igroup create -i [-t ostype] group [node ...]

Example
igroup create -i -t windows payroll_server
iqn.1991-05.com.microsoft:eng1

Result
Data ONTAP creates an igroup with -i, the iSCSI option, the operating system Windows, the name payroll, and the node name iqn.1991-05.com.microsoft:eng1.
2 Enter the following command to create a LUN:

lun create -s size [-t type] lun-path

Example
lun create -s 48g -t windows
/vol/vol1/qtree_1/payroll_lun

Result
Data ONTAP creates a LUN with a size of 48 GB, of the type Windows, and with the name and path /vol/vol1/qtree_1/payroll_lun.

3 Enter the following command to map the LUN to the igroup with a SCSI ID:

lun map lun-path initiator-group scsi-lun

Example
lun map /vol/vol1/qtree_1/payroll_lun
payroll_server 1

Result
Data ONTAP maps the /vol/vol_name/qtree_1/payroll_lun LUN to the payroll_server igroup with a LUN ID of 1.

4 Save the contents of host file system buffers to disk using the command provided by your host operating system, or by using SnapDrive 2.0 or later for Windows systems.

5 Create a snapshot by using SnapDrive 2.0 for Windows systems, or enter the following command for non-Windows systems:

snap create volume_name snapshot_name

Example
snap create vol1 payroll_backup


6 Enter the following command to create a new LUN in the active file system so that it can be mapped to the backup server from the existing snapshot:

lun create -b snapshot lun-path lun-path

Example
lun create -b
vol/vol1/.snapshot/payroll_backup/qtree_1/payroll_lun
/vol/vol1/qtree_1/payroll_backup_lun


7 Enter the following command to map the new LUN you created to the backup host:

(backup_server is an igroup that already exists for the backup host.)

lun map lun-path initiator-group scsi-lun

Example
lun map /vol/vol_name/qtree_1/payroll_lun
payroll_server 1

Result
Data ONTAP maps the LUN /vol/vol_name/qtree_1/payroll_lun to the igroup payroll_server with a SCSI ID of 1.

8 Back up the data in the new LUN from the backup host to tape using your SAN backup application.

9 Take the backup LUN offline by entering the following command:

lun offline /vol/vol_name/qtree_name/lun_name

Example
lun offline /vol/vol1/qtree1/payroll_backup_lun


10 Remove the snapshot by entering the following command:

snap delete volume_name lun_name

Example
snap delete vol1 payroll_backup

挺具体了吧，呵呵

果然不出我所料，得找个主机MAP SNAPSHOT LUN，够费劲的 全得手工做

badstar

滋毛儿大人，感谢你贴出来的命令
我想做个脚本来每天定时作 snapshot->;将snapshot挂接到备份服务器->;从lun中将文件备份到tape-->;备份结束将snapshot断开-->;等待定时器
但是每一步的成功或者失败能从脚本上反映出来吗？例如写tape成功了执行下一步断开snapshot？

gofi

脚本支持条件语句吗？
