Frequently asked questions
What is the most common cause of data loss?
Hardware failure and human error account for the majority of incidents — drives wear out, controllers fail, and files or volumes get deleted, reformatted or overwritten by mistake.
Can data lost to ransomware be recovered without paying?
Sometimes. Recovery depends on the strain, whether shadow copies survived, and whether clean backups exist. Professional recovery focuses on intact backups, partial decryption, and unencrypted artefacts left on the system.
What is the single best prevention measure?
A tested 3-2-1 backup strategy: three copies of the data, on two different media, with one copy off-site. Untested backups regularly turn out to be unusable when needed.
