- account setup in just 4 simple steps
- backup snapshots are created after a backup completed successfully
- deletion protection: no write access to snapshotted backup data by backup credentials
- GUI supported command line generation for fast restore of single directories/files
- direct access to snapshots/directories/files without waiting
Security & Reliability
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.
- pre-notification by email if estimated required backup space is running out
- optional notification if there was no backup for x hours
SSH keys to secure the login for backup system users. Deletion protection: no write access to snapshotted backup data by backup credentials.
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.
- 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.
