[Can I set up a pool on multiple external drives to use as offsite backup?]

 

IIRC, the problem with that, is that we could really only ensure this for stuff accessing the pool.  
While it may be possible to do this for other file access, I'm not sure that's a good idea (or even safe, really)

I don't think you need to handle it for file access outside of the pool. Windows and other apps already do that.

If Drivepool would "eject" the pool, at least in the sense that Drivepool itself wasn't holding a lock on anything on the drive, the drive(s) could then be ejected in Windows like any other drive. Ideally the Drivepool eject would pause any duplication or balancing operations for the ejected pool. I mention that because of a post I saw about a bug that was causing either Drivepool or Scanner to run unnecessary operations on a drive under certain circumstances. Maybe the eject needs to pause Scanner also?

Yes, you can do this. And there are several people that do.

However, there is no good way to eject the disks, as the normal way will likely fail (i've had issues with regular disks being ejected...)

Exactly. And I get that with regular disks, even.

 

You could set the disks as offline in disk management. But you'll need to remember to set them as online when you reconnect them.  Or .... you can just pull them, if you're sure they're done being written to.

 

It would be great if Drivepool just had an "eject" button of its own, which just closed all files it had open on the selected pool/drive. It's impossible to really be sure that nothing is writing to the drive at the moment you pull the power or set it to offline.

The other option would be to setup your external drives as a new, separate pool, and then use Sync software to mirror both pools from a file-level (with the data pool being the master).  It would really be the easiest and cleanest option, in my opinion.

I tried doing this before posting my question, but when I try to safely eject the drives using the normal USB drive eject option in the system tray, it says the drive is in use and can't be ejected. It even did that after I created the pool but hadn't copied any files to it. I tried that to see if it would work before wasting time copying a bunch of files to it. I assumed that it must be Drivepool that has a lock on the drive that's preventing it from being ejected. 

I've used Goodsync in the past to do this to a single drive. I'm just trying to get it working with multiple drives in an external pool.

I have a pool consisting of local disks that I need to find a backup solution for. I purchased a couple of 8TB USB drives that I would like to use for backup. The easiest way for me to back up would be to put the two USB drives in a pool and use a utility like Fastcopy to copy everything from the local pool to the external/USB pool a couple of times a month.

Is it possible to do this? Once the files are copied, how can I "eject" the pool safely so I can reconnect it the next time I want to do a backup? I had the idea of putting the USB drives in a pool so that I wouldn't have to manually sort which files to copy to each external drive and just let Drivepool handle that by making the two drives look like one big drive.
