Whats the best way to manage your recovered data ?

Once NTFS imaging (DDI) is completed the data is then extracted (DRE, R-Studio, etc.) to an external NTFS data store via USB 3.1.
From here, it is then transferred to a thumb drive or external HDD and with large volumes of data / files, this part can take many many hours.
The NTFS store keeps client data for a few weeks, incase of further issues, and then gets deleted.

HFS+ imaging, data extraction and then transferring is the same as above, to its own external HFS+ store.

Question:

Is it possible to centrally manage the data from these different filing systems ?
example: 1 RAID enclosure / server (partitioned), able to be simultaneously connected to multiple devices (a Mac & pc) or does it have to remain separate ?

Also I'm looking to find a solution (if there is one) where I can transfer the extracted data, from the data store to the clients new device, in a faster time.

How do you guys handle this ?

Thanks in advance :D

Seems to me like you're adding some unnecessary steps.

Here's what I do. I've got 80TB of direct attached storage on my PC-3000 Express machine (what I use most often for imaging). It's a couple RAID 6 arrays using 4Tb HGST SAS drives and an Areca RAID card. I image the data to image files rather than a bare drive unless it's a large/full drive.

Then when I do the logical recovery, it's straight to the destination drive we'll be returning to the customer whatever that may be (usually a USB 3.0 external if they buy one from us)

Personally, I can't see any purpose of doing a file extraction to your own shop drive before copying to the return media. You can always just extract the files again from the image if necessary.

Then I keep the image files for two weeks the data return date before I erase the files to free up space.

Thanks for your reply Jared.

I can't image to files as my DDI won't let me, has to be to bare drives, then I extract from there.

Where its getting messy, is with the HFS+ DR jobs as I'm doing the extracting using a Mac.
I was told to always use a Mac to extract from the image (if its HFS+) so it retains the structure.
If everything was being extracted via windows (NTFS) then I could solve my issue easily.

I was thinking maybe a NAS setup maybe a solution to centrally manage the data for now but I'm unsure if that would do whats needed.

NAS is going to be slow unless you're setting it all up using 10Gbps NICs, but that's a bit costly to buy all that equipment.

I do pretty much everything in Windows unless I absolutely need to use a Mac (which I do have a few sitting here). Mac Drive is a good program which allows formatting and copying data to HFS+ formatted drives. It's certainly not without its flaws, but sufficient for most cases. You just have to be sure to safe eject drives, and I've found it's best to only ever have one HFS formatted drive connected at a time.

With DDI though, you are pretty limited to just using bare drives to direct clone to. I've got DDI 4 sitting here, but I don't use it very often since upgrading to the Express system.

Yeah the 10Gbps NAS option is off the table at mo, so it would have to be some kind of DAS setup then.

Maybe if I could come up with a DAS solution (not as enormous at yours) that I could have a HFS+ partition and an NTFS partition, that would be good for now.
(Not sure, yet, how I could extract using a Mac onto it, maybe the Mac drive software you mentioned would rule out the need for extracting using a Mac)

Have you got your 20 drives in a rack chassis and how is that connected to your pc-3000, thunderbolt ?

Ill take look at the Mac drive solution and see if I can incorporate into my setup.
