Hello, I am going to migrate from synology and researching options.

My family heavily use following applications. So it is important for me to substitude them properly.

synology quickconnect, synology drive which provides file syncing similar to syncthing but one can download if needed automatically etc. synology photos 2fa authentication

I personally use notification (without personal smtp provider) hyperbackup antivirus snaphots and replication.

What are the comparable well established alternatives in unraid?

It all comes down to what you want it to do and how you want to interact with it. I persaonly don't like synolgy software, os eco systems... there HD caddy are ok but its a bare min nas nothing more... Simlar to the unifi UNAS... ITs for this one specfic use case...

unraid would implement dockers VMs and LXC to esental run the equilven software. We could use user script plugin and bash scripting to implament a greate deal of things.

Per your list here is a general Table of dockers one would implement on Unraid...

Synology feature	Unraid-native / plugin	Well-established alternatives (Docker on Unraid)	Notes / when to pick
QuickConnect (easy remote access, no port-forwarding)	WireGuard VPN (built into Unraid)	Tailscale (mesh VPN, 1-click on most devices), ZeroTier, Cloudflare Tunnel (no open ports)	For “just works” family access: Tailscale. For self-hosted VPN: WireGuard. For public URLs without opening ports: Cloudflare Tunnel.
Drive (sync + on-demand fetch)	—	Nextcloud (desktop client supports Virtual Files/placeholder sync), Seafile (fast delta sync), Syncthing (pure P2P, no server), Resilio (proprietary, robust)	If you want a “Drive + web suite”, pick Nextcloud. If you care most about sync performance, Seafile. If you want zero server and LAN-smart, Syncthing.
Photos (family gallery, face recognition)	—	Immich (best-in-class mobile backup + face/places), PhotoPrism, LibrePhotos, Nextcloud Photos	Immich is the current favorite for families migrating from Synology Photos. Store originals on a ZFS/Btrfs pool.
2FA authentication (for admin & apps)	Unraid GUI 2FA (TOTP)	Authelia or Authentik in front of your apps (with Nginx Proxy Manager or Caddy)	Unraid itself can do TOTP. For all app UIs, put a single-sign-on/2FA gateway (Authelia/Authentik) in front. Supports TOTP/WebAuthn.
Notifications (no personal SMTP)	Settings → Notifications (multiple agents)	Apprise (sends to 70+ services), ntfy, Pushover, Telegram, Discord	Unraid can notify via non-SMTP channels. If you want one tool to fan out to many, run Apprise and point jobs at it.
Hyper Backup (versioned backups to local/remote)	Appdata Backup/Restore (plugin for Docker configs)	Kopia, Restic, Borg (Vorta GUI), Duplicati, UrBackup, rclone (copy/sync to S3/Backblaze/Wasabi)	“Set-and-forget” + dedupe/encryption: Kopia/Restic. Windows/Mac endpoints: UrBackup. Simple mirror/tiers: rclone. many rsync scripts exist on the forum as well...
Antivirus	—	ClamAV container (clamd + clamscan), ICAP/ClamAV with proxy, client-side AV on PCs	Schedule clamscan against shares or scan on-upload behind a proxy. Most home setups rely on endpoint AV + periodic ClamAV.
Snapshots	ZFS pools (Unraid 6.12+), Btrfs (cache/pools)	Sanoid/Syncoid (ZFS snapshots + replication), zrepl, znapzend; for Btrfs: btrbk, snapper	Unraid’s parity array has no snapshots. Put important data on ZFS (recommended) or Btrfs pools to get snapshots/replication. Depends on how you setup your uraid disks....
Replication	—	ZFS send/recv via Sanoid/Syncoid or zrepl; rclone/rsync for file-level	ZFS is the closest feel to Synology’s snapshot-replication. For cloud/object storage, use rclone or Kopia/Restic backends.

A sane starter stack (mirrors Synology feel)

• Remote access: Tailscale (family devices) or WireGuard (built-in) + Cloudflare Tunnel for public links without port-forwarding.

• Drive + Photos: Nextcloud (files, sharing, web) plus Immich (phone auto-backup, face/places). Many folks keep media in Immich and documents in Nextcloud.

• Reverse-proxy + SSO/2FA: Nginx Proxy Manager (easy) or Caddy (auto-TLS) + Authelia/Authentik (enforce login + 2FA for all app UIs).

• Backups:

  • Kopia or Restic to Backblaze/Wasabi/S3 (encrypted, deduped, versioned).

  • Appdata Backup/Restore plugin for Docker configs.

  • Optional UrBackup for PC images/file versioning.

• Snapshots/replication: Use a ZFS pool for important shares → Sanoid/Syncoid for scheduled snapshots + push to another server/NAS.

• Notifications: Configure Unraid Notifications to Pushover/Telegram/Discord, or centralize with Apprise.

• AV: Run ClamAV weekly over shared folders or rely on endpoint AV + upload-time scanning if you proxy.

Practical tips migrating from Synology

• Data layout: Put “needs snapshots” data on ZFS. Keep bulk, cold data on the Unraid array if you like its expandability; you can still cache it via ZFS/Btrfs pools.

• Shares: Export via SMB/NFS as before. Unraid’s Users/Shares UI maps cleanly.

• Photos import: Point Immich at your existing library; it will (re)index faces/places. Keep originals immutable via ZFS readonly snapshots.

• Drive clients: Nextcloud desktop supports Virtual Files (on-demand), close to Synology Drive’s behavior.

• No-ports remote: Prefer Tailscale for family; if you need public links, add Cloudflare Tunnel to just the reverse proxy.
  

Alot of people migrate off synology for unraid abilty to run dockers and systems. If it exsit on docker hub and will most likley run on unraid. Quite a bit of content exist in the unriad CA

https://hacktobeer.eu/posts/synunraid/

I use unraid no disk 1 array setup Pool devices only.

I implement a sinlge nvem/ssd cache disk for docker appdata.
I implement a raid z1 pool for main data stores.

I run quite a bit of service systems and applications.

I've settled with sftp and fail2ban for file sharing and access
I've use plex for media shaing and access
I've use immich for phone backups and sahring

I've implemented tail scale where i can conect and access all my content

Each may require some fiddling setup and configs but once up that's it no more fus and it works / lasts.

2fa totp can be a bit trickey to implement and honestly its not worth the fight for some....

I would recommend checking out the CA
