如何備份Trucluster

Hello David:



For Tru64 UNIX/TruCluster, you can use vdump

for backup and vrestore for restore data from

vdump, and the following is one example:



# vdump 0uf /dev/tape/tape1_d1 /

# vdump 0uf /dev/tape/tape1_d1 /usr

# vdump 0uf /dev/tape/tape1_d1 /var



The same commands for Tru64 UNIX/TruCluster.

如何備份Trucluster

Hello TruCluster users:



Owing to typing error in previous reply, so

I re-post this attachment again, please keep a

copy of your system configuration by running

"sys_check -all > `hostname -s`.html", so if

it is unlucky for you to lost TruCluster system

or data disks, you can following the attachment

as guideline to restore system/data from backup

tapes, except H/W mirror for you important

disks, you need to perform regular backup by

OS command: vdump or your other backup solution.



Please right click @ then save as file for

your reference.

Hi, Danny

Thanks...

One more question. 在台灣有客戶實際成功restore TruCluster的例子嗎?(using fibre channel storage)

如何備份Trucluster

Hello David:



我所處理過的cases, 絕大部分都使用mirror disks,

所以還沒有客戶真正做過disaster recover. 如果貴公司

有足夠的資源, two alpha servers, one shared

storage, so you can use your existing backup

tapes to craete one testing TruCluster by using

the disaster guideline, and don't forget to

disconnect network cables before changing all

related hostname and IP addresses for networks,

otherwise, it will conflict with your existing

TruCluster's ip addresses, and the following

is the "how to change TruCluster IP addresses"
