Storage needs rarely grow in a straight line. A server that shipped with 2 TB of NVMe runs fine for a year, and then backups, logs, media files and application data quietly fill the disk faster than anyone planned for. The usual reflex — order another server, configure RAID, install an OS, start maintaining another piece of hardware — is a lot of infrastructure to solve what is, fundamentally, a capacity problem. And if what you're actually solving for is backups specifically, storing them on the same server they're meant to protect defeats the purpose: if that server fails or gets compromised, the backup goes with it. This is exactly the gap that mountable, offsite cloud storage is built to close.
10 TB Storage Without Buying Another Server
Here's the problem in its most common form. A company is running:
Dedicated Server
├── 2 TB NVMe
├── applications
├── databases
└── websites
That 2 TB is fully allocated to what the server is actually doing. Now the company needs another 10 TB — for backups, archives, or a growing media library. The traditional path looks like this:
That's a full second system to provision, patch, monitor and eventually replace — just to hold data, not to run anything. For backup and archive use cases, none of that operational overhead is actually necessary.
The alternative:
Enterprise Storage attaches to a server you already have — in any region, on any provider — as an additional mounted disk, over a standard protocol. There's no operating system to install, no RAID to configure, and no hardware to monitor on your end. Mount it, and it behaves like local storage from the application's point of view:
The same storage can also be mounted over SMB or NFS on macOS and Linux, or accessed via SFTP, FTPS or WebDAV directly from Windows, backup software, or NAS devices — whichever protocol your existing tooling already speaks.
Why Offsite Storage Matters for Backups Specifically
If backup storage is the primary use case, the placement matters as much as the capacity. The standard reference point is the 3-2-1 rule: three copies of your data, on two different types of media, with at least one copy offsite. A second disk or partition on the same server satisfies none of that — it's still one machine, one power supply, one point of failure. A ransomware event or hardware failure that takes down the server takes the "backup" with it.
Offsite storage on separate infrastructure removes that shared failure domain. For businesses operating in or serving the EU, keeping that offsite copy within Europe also matters for data residency and GDPR compliance — an offsite backup stored outside the EU can introduce the same compliance questions as your primary data.
What Can You Use 10 TB of Storage For?
10 TB covers a wide range of practical use cases, and most organizations end up using it for more than one at the same time:
- Server backups — scheduled, automated backups from physical or virtual servers
- Proxmox backups — offloading VM and container backup targets outside the hypervisor host
- NAS replication — a second copy of Synology, QNAP or TrueNAS data outside your local network
- Synology backup — Hyper Backup or similar jobs writing to an external, secure destination
- Website backups — full site and database dumps kept separate from the production server
- Video & media libraries — footage, renders and production assets too large for local disks
- Photography — full-resolution archives and client delivery files
- Business documents — company files accessible across workstations and offices
- Application data — storage for automation tools, pipelines and custom software
- Long-term archives — files that must stay accessible but don't need to sit on fast local disks
How Much Backup Storage Do You Actually Need
Sizing isn't about matching your server's total disk size — it's about your retention policy multiplied by what actually needs to be retained.
1 TB typically covers a single website with database, application config, and a few weeks of retained daily backups — the common case for small business sites and single-application servers.
5 TB fits a small-to-mid dedicated server running multiple applications or databases, several weeks of retained snapshots, or a NAS replication job for a home or small-office Synology/QNAP setup.
10 TB is the practical starting point for Proxmox or VMware backup targets (VM images are large and retention adds up fast), multi-server environments backing up to one central location, or a media-heavy business needing both backups and archive storage in one place.
A rough sizing method: take your current data size, multiply by your retention count (how many backup generations you keep), and add 20–30% headroom for growth. That number, not your server's raw disk size, is the capacity to actually buy.
Connecting Your Existing Backup Tools
The value of offsite storage depends on how painless it is to push backups to it. Enterprise-grade storage should support the protocols your existing tooling already uses, rather than requiring new software.
Proxmox can add remote storage as a backup target directly, letting scheduled VM and container backups write offsite without any change to the backup jobs themselves.
Synology and QNAP NAS systems support SFTP and WebDAV destinations natively through Hyper Backup or equivalent apps — pointing an existing backup job at offsite storage instead of a local external drive.
cPanel, Plesk and custom scripts can write to a remote destination over SFTP/FTPS or an SSHFS-mounted path, the same way they'd write to local disk.
In every case, the setup is the same shape: point your existing backup job at a new destination. No new backup software to learn, no agents to install on the server being backed up.
Pricing
Storage is billed monthly based on the capacity assigned to your service, with no setup fee and no long-term commitment. 1 TB starts at €50/month. 5 TB runs €90/month — €18 per TB. 10 TB runs €140/month — €14 per TB. As the examples show, the price per TB drops meaningfully as capacity increases, which is the usual pattern with storage-as-a-service pricing.
For environments that need more than 10 TB — multiple servers backing up to one pool, long retention windows, or large media archives — custom configurations scaling up to 100 TB are available on request, priced against the same per-TB curve.
Capacity can be increased at any time without migrating existing data or backups to a new destination — the mount point and connection details stay the same as capacity grows. The price per TB drops as capacity increases, but the more relevant comparison is against the alternative: a second server, its hardware cost, its power and rack space, and the ongoing time spent keeping it patched and monitored. Ten terabytes of pure storage capacity almost never justifies that overhead.
Who This Is For
Businesses running a dedicated server or VPS that's filling up — where the constraint is capacity, not compute, and buying more compute to get more disk space doesn't make sense.
Teams running Proxmox or VMware that need an external backup target so VM snapshots aren't competing for space with the VMs themselves.
NAS owners (Synology, QNAP, TrueNAS) who want an offsite copy of their data without building or renting a second physical NAS elsewhere.
Agencies and studios with growing media libraries — video, photography, design files — that need a shared, mountable location accessible from multiple workstations.
Anyone whose current backup strategy is "on the same server it's backing up" — which technically works until the day that server has a problem, at which point it doesn't.
Frequently Asked Questions
Is this a backup service, or just storage?
It's the storage destination — you point your existing backup software or scripts (Proxmox, Synology Hyper Backup, rsync, cPanel, etc.) at it. This keeps you in control of retention policy and scheduling rather than locking you into a specific backup product.
Can multiple servers back up to the same storage?
Yes — unlimited simultaneous connections mean multiple servers, NAS devices or workstations can write to the same storage service, each to its own directory.
What happens if a backup is accidentally deleted or overwritten?
Daily snapshots allow recovery of previous file versions, adding a layer of protection beyond whatever retention your backup software itself manages.
Do I need to migrate data if I need more than 10 TB later?
No. Capacity can be increased on the existing service without rebuilding the mount point or moving data to a new instance.
Where is the data physically stored?
In EWADC's data center infrastructure in Warsaw, Poland — keeping offsite backup data within the EU for businesses with data residency requirements.
