So I have a NUC with Proxmox as the primary OS and OPNsense in a VM for my home network. I've been trying to move away from Google services but would still like to use them as a back up solution. Would it make sense to use Nextcloud in a VM as a replacement and use Rclone to encrypt and backup my files to Google Drive? Or should I use a NAS OS like Open Media Vault instead?
I'll also mention that I have an empty SSD that I can passthrough and that my primary draw to Nextcloud is that they have a Windows desktop syncing app like Google Drive does which makes things familiar and convenient. I don't plan on having my Nextcloud instance exposed to the web but might setup a Wireguard tunnel into the local network in the future.
If you are doing just local syncs the simplest solution might be rsync.
As for a solution with nice software clients, I use Seafile. Nextcloud is nice but it’s incredibly slow to sync files in my experience.
Another local option might be syncthing.
As for backup I use Rclone to do encrypted backups to GCPs Archive Srorage tier. The price is really good at $0.0012 USD / GB. 1TB of backups is like $1.25 USD per month. Be warned though retrieval costs are high.
Thanks for the recommendation. I'll look more into Seafile. It's much closer to what I want than Nextcloud since I don't need all the extra services, but the downside from what I've read is that it doesn't allow for file access from the host OS and that parts of the code is proprietary.
I was also choosing between seafile and nextcloud for a syncing and sharing solution. The no host access to files was a deal breaker for me. Having settled in with nextcloud for a year I would say it's still worth a test drive. The web ui is sluggish, but syncing seems fine. It definitely hits the ceiling for read/write speed in my environment, and the windows app picks up changes in the sync directory in seconds. I haven't methodically tested how long it takes for a change made on Android to propagate to the PC, but going on memory from real world use it would be a few minutes at most.
You could also consider a lesser known product, Duplicati. It creates encrypted 50MB chunks of data and maintains a database of what's in it. Have those chunks in Google Drive, and you have your encrypted backups in the cloud.
Duplicati looks very promising, but from a cursory glance it's more for backups? Since the files are split into chunks, I would still need to use a NAS or local cloud storage and have Duplicati do the final upload to GDrive.
I ultimately did go with Syncthing and uploading my files encrypted to Google Drive for backup. It's been working great for months. I've also been using Zeroteir to make this work with my laptop too while on the go.
Try Resilio Sync. Running it for 5+ years now and did not have a single synchronization issue. Syncing around 5 devices flawlessly, instantly and error free (not sponsored)
