Hello, i plan to suggest a proxmox solution to my client but im not sure of one thing about DRBD, and before i outline it to him i would like to ask for some pointers.

Here's a really basic outline what i want to do. Two identical servers in two places running same hardware and setup. My first plan was to replicate ZFS periodically (once a day probably) but then i heard about DRBD. Can i use DRBD as a replication service and not as a redundancy service? My plan for redundancy in case of main server failure was to let someone drive to the second site, grab the replicated server and replug everything back on the main site. I cannot use DRBD as a failover because i plan to use the server as a router too so if server fails, connectivity in the main site also fails. Separate router is probably not an option due to cost associated with another server needed for that (unless you know how to do it on the cheap).
I know this is quite janky solution but the business of my client is quite small atm. (around 12 devices 8 users) and cost constraints are quite high.
Main site internet is around 125Mbits symmetric and second location hasn't been decided on yet but expect home location with limited bandwith around 30/10 down/up. No data caps. Daily data throughput wouldn't be big 10gb at most with occasional larger spikes up to 50gb every few weeks.
For the servers i plan to use refurbished poweredge dell servers, i haven't decided on the exact hardware but don't expect something spectacular 2x quad core Xeons, 32+ gb of ECC ram, 3-4 gigabit network ports. ZFS pools will be around 10TB (space needs werent discussed yet) and i plan to keep VM data of Zentyal and pfsense on freenas and keep proxmox and freenas data on mirrored sata dom 32gb (also replicated onto zfs pool).
I already discussed it with few of my colleagues and general setup seems okay but if you spotted some major flaw please tell me.
Also to recap my main concern:
Can DRBD be used as a replication service so when main server fails and someone brings second server and replugs everything will it work plug and play?
Thanks !
