Throwing this open to the brains trust..!
My current NAS setup is a DS918+ which runs a weekly Shared Folder Sync to a second DS918+ unit at the same location, and an offsite backup performed monthly to a DS718+. This has worked flawlessly since inception. My usage is mainly storage and some VMs/docker apps, Plex, with probably an 80% read / 20% write ratio. Roughly 20TB of data, of which less than 50GB changes from month to month. I have 7 shares, of which 4 are effectively archive/read-only, and user home folders are in use heavily on the main NAS.
Due to a change in my working environment, I now have a requirement to run a NAS in two locations. I am thinking about moving to a setup with a DS918+ in each location, using a better synchronization method for the two DS918s, and use the offsite DS718+ NAS for backup. Most of my shares are relatively static, with a couple that I would ideally like to have two-way syncing for. I will work from both locations, so ideally I would like to upload data in each location and let the NASes handle the syncing.
My main location has an RT2600ac, the second site has an MR2200ac. Both sites have 50Mbps down / 20Mbps Internet connection, so effectively a 20Mbps pipe, though I'd consider limiting replication traffic during daytime hours. I'm thinking a Site-to-site VPN may be the go here, both devices have a synology.me DDNS and Quickconnect enabled.
What I'm struggling with is deciding the best method (or methods, if multiple methods would work best):
1) Can I run HA over two sites? Can I run HA over a site-to-site VPN? or is HA overkill for this context?
2) Would Snapshot Replication work better than HA? (ideally with bidirectional sync).
3) Can I use Drive to manage file upload tasks for both locations, or is it a single-NAS solution only?
4) Is Drive ShareSync better than Snapshot Replication for my use case?
I'm happy to continue using Shared Folder Sync between primary NAS/secondary NAS for now, but I'm thinking this may be a great opportunity to tie down a better usage paradigm.
All suggestions welcome!
