Recover lost data after new drive install

Question

WHS 2011 System set up is:

C:/ SSD, Two 2TB HDD in the pool, One 2 TB as system backup (USB external).
I had a failing drive. System backup only did a partial backup.
I replaced the drive, let DP do its work, then found a lot of missing files.  I assume they were on the failed drive.  When I try to do a restore files from the external drive, I can only access ones the were created after the new drive was installed.  All previous backups listed are grayed out and not accessible for retrieval.  I think the data is still on the external system backup drive but I don't know how to retrieve it.  Any suggestions?  Thank you.

We would need a bit more info. Did you have duplication? What amount of data did you have on the Pool?

I fear though that your backups are lost. You have two 2TB HDDs that you backup (I think) to a 2TB HDD. Server Backup does try to retain backups but once the backup HDD becomes full, it will wipe and do a new fresh full backup. As you have added a new HDD and that HDD will have had data on it, chances are that the BUP HDD got full and wiped.

This is speculation on my part.

What you could try to do is to locate the large .vhd files on the BUP HDD and have explorer show the "Date created". My guess is that it will show August 31st, around 1 AM...

This is (one of the) the reason(s) why my BUP HDD is far larger than the amount of data to be backed up and why I have rotating BUP HDDs...

No, I did not have duplication.  Please see images for more info.

I don't know how to isolate the BUP HDD in explorer to view date created.

Would it matter that the drives in the pool were renamed when the new HDD was added?

Thank you.  The oldest date for a .vhd file is 9/1/19.

 I think you are right about over writing.  When I installed the new drive I failed to uncheck the box to back up "Videos" (689 GB).  I normally don't do a server back up for videos so that is what took up so much space.  I still hope there is some way to recover my lost data.  Thanks for your help.  If you have any other suggestions please pass along.

That is Date modified. You can add a column for date created and that is what I am looking for. Date modified will always be the last date you ran a backup and that is fine.

TBH, I don't think there is a way to recover.

Sadly, I think you are right.  My only hope that the failed drive can be made operable enough to retrieve the data.  I so, what procedure would you recommend to get it back?  Make a copy of the repaired drive or insert it back into the WHS box and make a backup or  ???

So that is not my expertise (as if I have any) but if that failed drive would come to life, I would consider to not use it in your WHS box. I would want the strain on that disk to be minimal. So I would connect it to a PC, perhaps through an USB enclosure, and simply copy as much of the date of it as possible.

I think I would try to use a copy program that won't halt on issues with a file but continue with the next. Perhaps Robocopy can do this for you.

PS I was running WHS2011 until Christmas last year, still love it.

Thanks for the advise.  Since this was a pooled drive in WHS, how can I access and retrieve specific files/folders from a PC connection?

You are running WHS. Surely you have got clients with access to shared folders? Just connect the failed HDD, via a USB thingy for instance, and copy to the appropriate shared folders for instance.

Having said that, I would first copy from one HDD to another, just as it is fast and requires the smallest uptime for the failing HDD.
