The Digital preservation plan for research data and media related at LIB includes collection based research data, biodiversity monitoring, biobanking, and DNA sequencing data. This preservation plan is reviewed at last once a year, updates are done on change of one of the components.
Responsible for data storage is the Biodiversity informatics section, backup and archiving is in the responsibility of the IT department at LIB.
The primary storage for data is the curated storage level, i.e. storage that is accessible by clients for management of their data and consists of relational databases and files. Copies, database dumps and backups are stored on secondary storage, which is hard disk-based and on servers other than primary storage. For long-term archiving, the data is archived on tape. These tapes are stored with two identical copies at two different locations in the LIB.
The data and files are copied and archived on the following schedule:
Primary and secondary storage is done by the biodiversity section, long-term archiving by the IT department at LIB.
The funding for purchasing storage media comes from institutional budget plus additional funding from third parties. Responsible for setup and maintenance of storage media at LIB is the IT department.
The archiving workflow at LIB is setup according to OAIS standard. SIPs are preserved as they are received. AIPs are created from the curated original data on a regular basis. Both SIPs and AIPs are preserved long term.
The disaster planning covers following scenarios:
Responsible for assessment and recovery: the responsible departments for the different storage types are also responsible for the recovery. IT department: tape and hardware at LIB, Biodiversity informatics: hardware at Computing Center University of Bonn and software for primary and secondary storage.
Recovery of files on failure:
In case of file format obsolescence, i.e. unreadability of backup copies by the system in use, the data are restored from the backup text files.
Plans for obsolescence:
Responsible for integrity of digital files is the Biodiversity Informatics section at the LIB. Fixity checks are planned for the future with the setup of Tripwire to monitor file changes.
