Your data is stored with us –
and stays there.

Your data is encrypted before it leaves your premises, stored in data centres in Germany, and every backup run is monitored. In an emergency we bring back individual files or your entire data set. We operate the backup ourselves, as a processor under the GDPR; a cloud connection is set up only at your express request.

Encrypted from your server onwards

Data is encrypted on your own system. On our backup server it is stored in encrypted form only.

Stored in Germany

Your backups are kept in data centres in Germany. We run the service ourselves, as a processor under the GDPR.

Every run monitored

Every backup is logged and checked. If a run fails, we investigate the cause.

Quickly back in an emergency

Individual files, whole folders or a server's complete data set – to a different location if you wish, so that nothing is overwritten.

01

Two routes, one promise

How we back up
Route A

Servers in our data centre

Backup with Proxmox Backup Server

  • Incremental backup with deduplication: only what has changed is backed up, and identical data is stored only once.
  • Fast restore of entire virtual servers and of individual files.
  • Regular verification of the backups.
Route B

Systems at your premises and databases

for example practice and office servers, MS SQL Server or MariaDB

Backup with Bacula

  • Data is encrypted on your system before it is transferred securely to our data centre.
  • Running databases are backed up consistently and can be restored individually.
  • Retention in several generations; on request, an additional backup in a second data centre.
What we promise, on both routes
  • Stored in Germany: Your backups are stored in data centres in Germany – a cloud connection is set up only at your express request.
  • Operated by us: Netsource Data Systems operates the backup itself.
  • Data processing under the GDPR: We process your data as a processor under the GDPR.

What it gives you

Systems at your premises and databases

For systems at your premises and for databases we use Bacula, an open-source backup solution proven for more than 20 years. What you get:

Encrypted before the data leaves your premises

Your data is encrypted on your own system, with a separate key for each customer. Only encrypted data is stored on our backup server.

No open ports at your site

Your system opens the connection to us itself, secured by TLS (an encrypted connection). No inbound access has to be opened in your firewall.

Generations following the grandfather-father-son scheme

An incremental backup every day, a differential one every week and a full backup every month. We keep daily backups for 30 days, weekly ones for 8 weeks and monthly ones for 12 months, plus one annual backup.

Built for databases

We back up running databases consistently, that is in a coherent state: on Windows via the Volume Shadow Copy Service (VSS), and for MS SQL Server and MariaDB additionally via database exports. Individual databases can be restored selectively.

Every run monitored

Every backup run produces a log with result, data volume and duration. We see failed or unusual runs and follow them up.

Restore when you need it

From individual files to a server's entire data set, to a different location if you wish so that nothing is overwritten. If you like, you can restore yourself via a web portal with two-factor sign-in.

Restore verified

Before going live, we carry out a test restore. A documented restore test with a report, for example once a year, is available as an option, charged by effort.

Compressed and checksummed

Data is stored compressed. For every file we record a checksum that allows us to verify that backed-up and restored data match.

Clean client separation

Every customer has a separate, isolated area with its own storage and its own key.

Option: backup in a second data centre

On request, we additionally copy your backups to a second data centre at another location. We quote the price in our offer.

Grows with you

We add further servers or more data without rebuilding anything. You pay for the storage actually occupied.

Open source, proven for more than 20 years

No licence fees per device and no tie to a vendor. In use with us for Windows Server and Linux.

What about the cloud? Technically, Bacula can also be connected to S3 storage such as AWS. We set this up at your express request. We do not recommend it: for the sake of data sovereignty, your backups are best kept where we operate them ourselves — in data centres in Germany.

Process in four steps

4 steps
01

Initial consultation

We clarify which servers, systems and databases are to be backed up and which route suits them.

02

Setup

We set up the backup, either in our data centre or on your systems on site.

03

Test restore

Before the backup goes into operation, we carry out a test restore. This shows that the restore works.

04

Operation

We monitor every backup run, test restores regularly and restore data for you when needed.

FAQ

Frequent questions

6 questions
Q.01 Where are my backups stored?
We run the backup ourselves, in data centres in Germany. We ourselves do not use a US hyperscaler; a cloud connection is set up only at your express request. We process your data as a processor under the GDPR.
Q.02 Which software backs up my system?
We back up servers in our data centre with Proxmox Backup Server. Systems at your premises, such as practice and office servers, and databases such as MS SQL Server or MariaDB we back up with Bacula. The promise stays the same: your data is stored with us and stays there.
Q.03 How is it billed?
A monthly flat fee per backup job plus the occupied backup storage, per GB and month. We discuss setup and support in the initial consultation and set them out in your quote.
Q.04 What is a backup job?
The scheduled backup of one system, for example a server with its data and databases, on a fixed schedule and retention plan. If we back up several servers, each server is one job.
Q.05 Can you also back up to a cloud such as AWS?
Technically, Bacula can also be connected to S3 storage such as AWS. We set this up at your express request. We do not recommend it: for the sake of data sovereignty, your backups are best kept where we operate them ourselves — in data centres in Germany.
Q.06 Can I restore data myself?
With the Bacula backup, yes — if you wish, via a web portal with two-factor sign-in. Otherwise we restore for you, from individual files to an entire server.
