I also run a couple Synology units for ages but have had hiccups. I've had the OS fail requiring reinstall but all
MY data/drives were restored easily using their Hyper Backup app.
However, system settings and most app configs were not backed up as I had hoped and I did spend a day redoing all that annoying stuff.
BTRFS was an upgrade/default right before DSM version 7 IIR and I see it as a good upgrade. Snapshots and stuff make for easy backups especially on my VM's. The only bug I've experienced is with BTRFS and Plex in a Docker container. The tmp folder and btrfs didn't behave together and created a 5TB container that was a bit hard to track down because you have to SSH with admin to access the entire directory. After finding the rogue data, it was a simple fix.
Docker has a few quirks, but it is getting better. The DSM 6 version didn't have IPv6, but DSM 7 does. I consider it beta at this point because updates change/break things occasionally. Still, you get lots of functionality the official app store doesn't. There is no docker compose, and lots of crap doesn't install/work with the GUI tools. I've had the most success installing by script. Plex in a container works better than the package center version which is always out of date. Portainer seems to work better for me than the native app. Oh, even have had a minecraft container running for a few years.
Virtualization does take a bunch or resources. The CPU isn't... well it works for a NAS but loading an OS loading an OS takes some sweeeeet time. I run DSM 6 running DSM 7 in a VM. There are some app features I like that are no longer supported in DSM 7 and others that didn't exist in DSM 6. But once its up and running, Its nice and snappy. I upped the RAM myself from factory. It uses pretty available modules. There are CPU limitations so watch out for those. You can install more RAM than the CPU can address (if memory serves) and once it hits that threshold, weird things happen.
The Hyper backup app also has rsync destination capability along with cloud services like google too. Encrypted optional.
I used to use Cloudstation to sync data, but they converted to a app called Drive which didn't behave as I needed. I swapped everything to Syncthing and find that superior for syncing.
Hope this helps!
