Intermediate Archive

With the "Intermediate Archive", ZIH is closing the gap between a normal disk-based file system and Longterm Archive. The Intermediate Archive is a hierarchical file system with disks for buffering and tapes for storing research data.

Its intended use is the storage of research data for a maximal duration of 3 years. For storing the data after exceeding this time, the user has to supply essential metadata and migrate the files to the Longterm Archive. Until then, she/he has to keep track of her/his files.

Some more information:
  • Data will be stored in two copies on tape.
  • The bandwidth to this data is very limited. Hence, this file system must not be used directly as input or output for HPC jobs.

How to access the "Intermediate Archive"

For storing and restoring your data in/from the "Intermediate Archive" you can use the tool Datamover. To use the Datamover you have to login to Taurus (taurus.hrsk.tu-dresden.de).

Store data

dtcp -r /<directory> /archiv/<project or user>/<directory> # or
dtrsync -av /<directory> /archiv/<project or user>/<directory>

Restore data

dtcp -r /archiv/<project or user>/<directory> /<directory> # or
dtrsync -av /archiv/<project or user>/<directory> /<directory>

Examples

dtcp -r /scratch/rotscher/results /archiv/rotscher/ # or
dtrsync -av /scratch/rotscher/results /archiv/rotscher/results
