Security & Reliability

We are subject to German law. Our backup servers are located in a data center with a large number of GB peerings with all major network carriers. See more information at
The backup servers are running with a double-parity RAID-Z configuration, which means that one or two device failures can be sustained respectively, without any data loss.
Transport security by SSH, authentication by SSH keys. Optionally limit access to your accounts by networks/IPs/hostname restrictions. Optionally use a One-Time-Password to register at the web interface besides username and password.
  • pre-notification by email if estimated required backup space is running out
  • optional notification if there was no backup for x hours
No cancellation of running backups: TrustedSpace uses soft quotas before hitting hard quota limits. This allows overuse of the reserved backup storage to assure the completion of a running backup.
The web interface login is blocked for some minutes on login mistrials and you are notified about the problem. Optional additional usage of One-Time-Passwords.
SSH keys to secure the login for backup system users. Deletion protection: no write access to snapshotted backup data by backup credentials.


Just diffs have to be transferred after the initial full backup. E.g. add a rsync job in a system shutdown script to quickly backup the last changes of your working session before your system terminates. Or run rsync multiple times during the day to get more snapshots without locking down the system.
Diffs are stored after compression by lz4, backed by the ZFS filesystem.

Imagine you backup a system with 100 GB of data the first time and lz4 compression reduces the data by factor 2. So you need a 50 GB backup space for this initial backup.

Say, per nightly backup 1 GB of changed data is transferred by rsync to TrustedSpace. A snapshot is created after completion of the backup and therefore you would be instantly able to access the 100 GB of data from today, 100 GB from yesterday, 100 GB from the day before … and so on.

Still there is only 1 GB of data added by each snapshot to the backup space. And considering the compression factor of 2 you would only need 50 GB backup space and 0.5 GB for every additional snapshot in this sample.

You book a fixed storage volume for a fixed price. There are no costs depending on temporary overuse.
Consider all decisive factors:

  • compressed storage
  • only diffs between snapshots are being stored after the initial backup
  • effort to setup conventional backups at an offsite location plus addition of usability and security features
  • platform independence
  • fast restore capabilities

This makes TrustedSpace extremely cost effective in comparison to competing products.
