The ITMZ provides two different storage technologies designed and intended for digital longterm preservation of scientific data. The ITMZ only provides the service as bitstream preservation. In addition depending on the chosen technologie some metadata may be added to the stored digital artefacts (files/objects).

This object storage system is physical high redundant and distributed over three locations. Access is provided via an Amazon S3 compatible REST-API. The API may be used direct using a user-developed software or using compatible third party software. The intended field of use is for longterm archives which require live access on the preserved data. Files represented as objects in this case should only be written once and not modified again. Those files may be read in relative high frequency. A usecase for example is a online repository of the scientific data accessed by different users.

This object storage is based on a tape library as physical media for the bitstream. Access is provided via an Amazon S3 compatible REST-API. The API may be accessed direct using a user-developed software or using compatible third party software. The intended field of application is for preserving scientific data that does not need to be frequently accessed. Beeing aware of the access latency due to the process of loading, moving and copy of the data to a cache disk the data can be accessed at any time. Additionally it is possible to remove tape media physically and store it at a different location. The data is stored in LTFS on the tapes. Intended field of application are data repositories where the data is accessed never or at least less frequent but has to be preserved for a long period. Due to the possibilitie of removing tapes an export of a copy is possible as well. Additional application may be the requirement of moving data to different scientific facilities and import them there.
