NetWorker is one of the most advanced backup storage solutions on the market. As with other solutions, the migration of an existing NetWorker system to another product is extremely problematic.
The best approach to such a project is to get access to the data stored inside NetWorker with the built-in recovery function. In doing so, the compressed NetWorker files will be extracted to another storage space from where you can import the data into the new system. Normally, it is nearly impossible to import the metadata managed by NetWorker into the new hardware and backup solution. In most cases, you have to build the metadata of the new system from scratch and import the content into the appropriate folders or archives. Furthermore, NetWorker has a lot of features integrated into the system which makes it - if problems arise during the migration process - difficult to recover the backup.
Whether the NetWorker backup system is based upon tapes or hard disks, or a combination of both, the integration of deduplication and virtualisation of backup files when recovering a NetWorker backup is a complicated task. Only specialised professionals can - if a backup is damaged - recover the backup and rescue the data inside. In such a case, we review the accessible data and search for references, which lead to the original structure of the underlying and compressed data files, whether they were stored in virtual machines or deduplicated for faster use and file size reduction.
