I don't know if this is possible, but I'd like to set up QNAP Qsync to sync to Amazon S3 with some variations that may not have been tried before. I'd like to lay out my plan and invite any input that EE users may have that would steer me away from digging myself into a pit. Here is the plan:
1. Move data from a shared folder on a AD domain controller to a QSync folder on that same server. In theory this would require no more disk space on that server. Those folders could then be re-shared as before but would sync to the QNAP located on the LAN.
2. Sync the files on the QNAP to an Amazon S3 Cloud Folder
3. Share out the S3 files to remote users via a URL. (is this possible or will users need to use the QNAP utility and connect to the "private QNAP Cloud"?)
4. Set up Active Directory on the QNAP (very simple) and assign AD permissions to specific folders in the QSync area. (This step may not be necessary)
5. Provision Amazon's Active Directory service and sync the local AD domain to site to Amazon.
Assuming that the preceding steps were all possible, would it be necessary to assign user-level permissions in step 3?
If permissions were assigned on the Qsync level on the QNAP could those permissions be automatically replicated if AD is synced to the Amazon service?
As I said, I don't know if this plan is feasible due to any technical limitations, but if it is doable I think it would be a great platform for remote file access. LAN users would still access their mapped network drive as before but that data would sync to S3 for remote access. If this can all be done without even needing a NAS please let me know.
