mirrored disk backup


Hi all,

For machine no any mirror disk on it, i use dd and flarcreate utilities for backup. But now i have a machine both software and hardware mirrors on it. I don't want to use ufsdump or fssnap utilities for backup for this machine. Is there a way to backup the disk on this machine with the dd or another tool. The output of df as follows;

Thanks in advance,

machine1:~$ df -h
Filesystem size used avail capacity Mounted on
/dev/md/dsk/d20 51G 25G 26G 49% /
/proc 0K 0K 0K 0% /proc

fd 0K 0K 0K 0% /dev/fd

/dev/md/dsk/d100 67G 37G 30G 56% /DATA

Which partitions are you backing up, and where are you backing them up to?

You can always use a variety of tools if you choose. The question is generally what is appropriate for the situation and what works for you.

Why don't you want to use ufsdump or fssnap? Those are excellent tools.

What is the machine being used for? How active is it? Are you in an environment where a central backup server would be useful?

I don't want to ufsdump or fssnap, because the recovery process take more time (than the flash archive or dd tool).

I take my backup file on a 3300 Sun StoreEdge machine. And the backup i am interested on an active machine. I use NFS-mount to store backup file on StoreEdge.


The partion i wanted to be backup is /dev/md/dsk/d20 (root) partion.

thanks,
