I have two drive pools in Win 7 - each is set for pool file duplication, thus roughly halving the free capacity of the pool as a whole. Windows file explorer reports the free space as the true free space of the pool (as if there were no duplication anticipated). This presents a problem when doing a monthly FULL backup using a popular 3rd party backup (MR) - as the backup program looks for free space, sees twice what is actually available and then runs for hours before running out of space, instead of being able to see that it should first remove the oldest backup to make more room.
I realize that reporting the true free space is the technically correct solution, but wonder whether it would be possible to add a optional tick box instructing DP to report free space/duplication factor for those of us in this "niche problem" situation (as getting the vendors of every other program to write a Drive Pool aware check is simply not realisitic.
Thanks for listening or any suggestions you might have to help with this!
I was a bit to quick as I don't know your use-case. But if you run a server that is used by more people who could cause I/O on both partitions, then the HDD performance will suffer as the head actually needs to run from one partition to the other. But such a scenario might not at all be relevant for you. And heck, backups over performance, I say.
In any case, your 2-disk 2-partition plan will work (I had a similar setup for a while). If you have the budget and the machine is somewhat up-time critical, you might consider having a third 8TB HDD handy in case of a failure.
