Archive migration – if archives need to go looking for a new home

What should you do if your archives are on a storage system the support and maintenance of which will no longer be provided in the near future? Recently, experts for database archiving from CSP GmbH & Co. KG accompanied such a case at a large corporation in the energy sector


Chronos DB archive migration

The storage system EMC Centera will soon be switched off by its operator Dell. For this reason, the energy giant needed to find a new, reliable archive storage system. But how is it possible to migrate archives quickly and, what’s more important, in an unaltered form, as stipulated by the lawmakers, from one server to another?


This is how the migration to a new storage system works


The possibility to migrate archives, as provided by the database archiving software Chonos, provided the means for the energy company to easily switch to a new storage system. In a migration analysis prior to migration, it was established which and how many archives needed to be migrated, that is, relocated to a new storage system, and which was the target server. This enabled a smooth archive migration. The integrated hash-code check, which takes place during migration, guarantees that the archives will not be changed during the migration process. Revision-proof storage of the archives is thus continuously ensured.


These storage systems are currently supported by Chronos


With Chronos, it is possible to store archives on various storage technologies over the course of migration. Currently, these are, among others, AmazonS3, EMC ECS, FastLTA Silent Cubes and local file systems. Thanks to the dynamic structure of the database archiving software, depending on the customer’s requests, storage systems may also be connected with the help of an adapter.


When it’s time to think about archive migration


Migrating an archive always makes sense when a storage system is turned off. If maintenance and support are still ensured, a relocation to a second storage system should nevertheless be considered at an early point in time. Otherwise, bottlenecks as to the capacity for subsequent archiving projects are very well possible. Thinking about the relocation of the archive might also be a good idea if the costs for the used storage system are too high.
