Synology shows up everywhere in the client sites MSPs and repair shops support — file shares, small offices, practices that outgrew external drives. A NAS is great storage. By itself, it is not cloud backup for Synology workloads done right.
If you sell or manage backup for clients, the winning pattern is straightforward: branded backup agents on Windows and macOS endpoints, Synology C2 (or another cloud backend you choose) for offsite protection, and an optional local vault — on the machine, a fast USB drive, or a NAS the client already owns — for quick file restores. That is how most WholesaleBackup partners run cloud backup for Synology today: cloud offsite, local speed when you need it, your brand on the installer.
Why Cloud Backup for Synology Beats "NAS Only"
RAID on a Synology box handles disk failure. It does not handle ransomware hunting connected shares, admin mistakes, fire, or theft. The 3-2-1 rule still wins in 2026:
- Production data on workstations and servers
- A local copy for fast recovery (local vault or LAN target — often a NAS the client already has)
- An offsite cloud copy isolated from the production network
Cloud backup for Synology in an MSP stack usually means Synology C2 Object Storage as that offsite layer — S3-compatible, priced for backup workloads, familiar if the client already runs Synology gear. You are not trying to rank for Synology's own sync apps; you are offering your backup service, with your retention and monitoring, storing data in your C2 bucket.
How Partners Deploy Cloud Backup for Synology
Step 1 Your branded client
Build a white-label installer in the Backup Ops Web Console. Deploy to client endpoints via your RMM, silent install, or a one-off link. Same agent supports Windows and macOS; SQL, Exchange, imaging, and bare metal restore are in the base platform — not add-on modules.
Step 2 Synology C2 as the offsite vault
Point the brand at Synology C2. Our getting started guide walks through bucket setup: create a C2 bucket (name it wsbu-), generate read/write API keys, enter credentials in the brand build form, download the installer, run a test backup.
WholesaleBackup does not mark up C2 storage. You pay Synology directly; you set what you charge clients. Most partners see storage in the ~$6–7/TB range alongside a fixed per-endpoint software fee — workstations and servers priced the same, month-to-month, no per-restore fees.
Step 3 Local vault (where the NAS fits)
Enable a local vault on the endpoint or target a network share / NAS the client can reach on the LAN. On restore, the client pulls from local first, then from C2 for anything missing — fast day-to-day recovery without giving up offsite ransomware protection.
This is what "bulletproof backup hub" means for most shops: the Synology (or any NAS) is part of the local speed layer, while cloud backup for Synology via C2 is the offsite insurance. You can also run C2 alongside Wasabi, Backblaze B2, or AWS S3 per brand if you standardize on a different cloud — the platform is storage-agnostic.
What Happens During Backup
Under the hood, the client scans selections, then processes changes with a block differential engine:
- Files split into 1MB blocks
- Each block AES-256 encrypted, compressed, and checksummed
- Only new or changed blocks upload over SSL
- Restore reassembles, decrypts, and verifies
That design keeps bandwidth and cloud storage bills down — important when you price backup per seat, not per gigabyte. Status and health feed to Backup Ops so you see missed jobs, not just failed ones.
Recovery and Ransomware
Backups only count if restores work.
- Set retention and versions per client
- Test restores on a schedule
- Treat offsite backup as ransomware insurance: data encrypted before it leaves the endpoint, stored in a bucket production credentials do not touch
Local vault + C2 offsite is the combination our partners use after infections: last good version from before the event, without paying ransom.
Self-Hosted Option (Brief)
Some partners prefer to run everything on their own metal. WholesaleBackup Server on Windows Server is available for that model — popular with dedicated self-hosters who want full control of the vault on their LAN or SAN. Most new deployments we see go cloud-first (C2, Wasabi, B2) plus local vault; Server remains there when the business case fits.

Your response time to any and all my request is far superior to any customer service I’ve ever received my ENTIRE CAREER.
I am very impressed with the level of customer care and communication you have put forth into making sure that our setup with you guys goes smoothly. It is rare nowadays to find vendors that take pride in their products as well as show concern for a client’s well-being.
We were able to quickly restore our clients data without any issues using their last good backup – saving them from total data loss and stopping their business!
After trying multiple name brand backup vendors, we finally Partnered with WholesaleBackup and couldn’t be happier with the functionality and cost.
After using another white-label cloud backup solution for years, switching to WholesaleBackup has been a lifesaver. MUCH less maintenance, cost, bandwidth, and the U.S. based support is the stellar. The software and interface is SO much simpler and easy to use. I would recommend WholesaleBackup to any MSP looking to streamline their cloud backup system.
