backup with different hardware

[juno2]

If I have two unix server with different hardware conf. ( eg. server A & server B , can I use backup tape to backup whole system of server A and then restore it to server B ) ? thx.

Yes you can with the latest ignite software. You can get it from here: vers 4.1

You can see the features from here:

The best way to cut a tape is:

# /opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/0mn
be sure to use the no-rewind devices.

hi,

if you want the data backup's i guess yes. but if you are going to use ignite, it will not help.

Another question :
I have two unix server C & D with different hardware conf. , if server C 's HD is corrupted ( can't be boot) , can I just replace it with server D 'HD ? thx

hi Michael Tully ,
thx r reply , but how about if they are two server with different class

In answer to your first question:

No you can't just take the hard disk from one to another unless the drive itself is compatible and the hardware is compatible.
e.g. taking a 'A' class disk to 'A' class will work, but say an 'L' to an 'A' will not.

2nd question:

With the latest ignite version(s) you can create an ignite tape (make_tape_recovery) and use it on another class of server. Have a look at the link I posted earlier. It does actually mention this.

Hi Michael Tully ,

Do you mean the ignite tape is bootable ? I backup it from server A and then use this tape to bootup server B ? thx.

hi,
the ignite tapes are bootable ones.

check out the ignite man pages or the documentation.
