Hi, I am ready to mirror my Disk-0 500gb drive. I have been reading the forums in regards to mirroring. And I see there are some improvements coming. Should I wait for v2.04?

BTW, I have Ver 2.03 now

Hi Randy,

I'd do it right now. its going to take a while.
in terms of v2.04 it will have some changes as noted on this forum. like logging of the event and a few fixes. maybe a mirror NOW option?
500gb is a lot of data and worth backing up now.
when 2.04 is out it will just carry on where it left off once configured.

Randy its a good idea to have each 500gb hd on its own IDE channel this will be quicker.

Okay, I will give it a try. Will report back on how it went.

All went well. It took approx. 10 hours to mirror 485GB of data.
I think the documentation could use some tweaking. It just did not seem completely clear on the steps to safely complete the mirroring process. Some examples or descriptions would be nice. Maybe an appendix.

Just another question, is the mirror drive usable/read only? Or can it be written to by mistake?

Hi Randy,

What you can do is make the drive that has the backup RO, read only.
Rsync should remain RW. that should do the trick.

Hello gaiden:

I can't put my finger on the particular post, but I believe you said in that one that the Destination drive needs to be RW in order for a mirror to work ... contradicting the last post above.

I am testing mirroring with v2.03 (see http://www.serverelements.com/phpBB2/viewtopic.php?t=1677). The Destination is Disk-0 set to RW and also RSYNC is set to RW (although I think I can even disable Rsync at the Destination).

It would be great if I could set the mirror copy (Destination) Disk-0 to RO.

Please confirm. Thanks.

Georg

I have a 250GB Mirror setup (Source: Disk-0, Destination: Disk-3) Disk-0 is RW for RSYNC and SMB/CIFS; Disk-3 is RW for RSYNC and RO for SMB/CIFS. FTP is off. This seems to work perfectly and I can't delete from the mirror.

Hi georg,

RW needs to be enabled on the dest to allow the rsync to write to the dest.
if the other services are off then you can't delete the files on the mirror as NickC said.

I should have made my post a lot clearer
