Archiving Techniques Frank Klaproth EMANI – Project Meeting February 14th - 16th, 2002 Springer-Verlag Heidelberg Göttingen State and University Library(SUB) emani@mail.sub.uni-goettingen.de
General Remarks, Definition • What is archiving? • hold a: Digital copy, digital version, part of the digital original • make permanent accessible • „transport“ digital information lossless EMANI Project Meeting SUB Göttingen
The Situation at Göttingen ... • Using ADSM/TSM with HSM for archiving digitized materials (math journals, travel literature, spec. collections) in the GDZ • Cooperation with University Computer Center (GWDG) EMANI Project Meeting SUB Göttingen
... • 25 TB EMANI Project Meeting SUB Göttingen
... • Cooperation with GWDG / MRZ / VZG / SUB / MPG • Planned 2nd Data archive with 200 TB (up to 5.500 TB) • Testing LOCKSS EMANI Project Meeting SUB Göttingen
Environment - Hardware • processing units • x86, VC20, MIPS, RISC, ... • storage media • RO hardware (CD ROM, DVD) • RW hardware (CDRW, hard disk, floppy, tape, ...) EMANI Project Meeting SUB Göttingen
Environment - Software • Operating Systems • Unix (AIX, SiNIX, Solaris, Linux, FreeBSD, ...) • MS DOS, MS WinX, ... • MAC OS, ... • CPM • Applications • Text-, Graphic, Multimedia production tools • Reader, Presentation tools EMANI Project Meeting SUB Göttingen
Methods - Migration • Reasons for migration • Minimize variety • Time • („end of live“ of hard- and software) • emerging standards • Using standards makes migration possible • Different document formats and different hardwareenvironments EMANI Project Meeting SUB Göttingen
Methods - Emulation • emulation can follow migration • example: data on floppy disk migrates into a online storage medium (hard disk) • software can be emulated in a processing unit environment which handels data format from migrated floppy disk • VMWare (runs on Unix, MS WinX, MAC) • multiple OS with multiple software environments on one hardware environment EMANI Project Meeting SUB Göttingen
Other • access • handling and using URNs, persistent identifiers • signatures for documents • signatures for service /server provider • Trust Center EMANI Project Meeting SUB Göttingen
