Are you sure that your systems and your data are backed up regularly? Have you ever simulated a system failure in order to restore a full back-up?
Most companies are not aware about their IT infrastructure and especially about their back-up system.
Different back-up systems
Our engineers work on different types of back-up system (tape, external drive, externalised server etc.). We use different software vendors such as Microsoft, Symantec and others.
We regularly check our customers' backup systems to ensure that they are always available without any faults to the data. This requires that various types of back-ups are implemented: daily, weekly, monthly, remotely.
Back-ups should be made on removable media, with a copy being placed outside the company.
We also offer recoveries in case of crashes every 6 months or year, by restoration trial-runs of back-ups.
