Basic information on archive migration

Kurzinformation

In the second half of 2021, archive data will be migrated to an S3 storage infrastructure. Due to changes in technology and funding landscape, the archived data will be assigned to the future storage destinations Research Data Storage (RDS) - the research data repository and the digital archive.

The advantages of this storage infrastructure over the formerly used tape robot system are easier and faster retrieval of data via the S3 protocol, as well as easier access to the archived data. The retrieve of archived data that used to be quite time-consuming will become more convenient and efficient in the future. With the changeover, users will no longer be tied to a specific client or program. Programs that support the S3 protocol can then be used. These are, for example, Cyberduck or WinSCP.  In addition, security against data loss is significantly increased due to the geographical distribution of storage locations (geo-redundancy).


Detailinformation

Preparation of archive nodes

To prepare for the migration of archive nodes to the RDS and the digital archive, please refer to the menu item "Classification of archive nodes" for instructions and assistance.

Please note that the archive must be set to "Read Only" before entering the metadata. This is necessary to technically ensure that the archived data can be migrated completely.

All preparations and changes to archive nodes must therefore be made before "Read Only" is set. You will be informed in time about the archive access change to "Read Only".

More information about archive migration is available on the IT Center blog.

Viewing and categorizing archive nodes

Archive node contacts will receive an automatic email prior to the start of migration that includes a prompt to enter metadata. By entering the metadata, archive node contacts determine the future destination.

To assign archived data to the correct destination (Coscine or digital archive), it may be necessary to restore the files and directories from the archive.

Once the metadata has been entered, archive nodes can no longer be changed or edited. This is the only way to technically ensure that the archived data is migrated completely. For this reason, it is recommended that you review and edit the archive data before entering the metadata.

The following instructions describe how to restore files from the archive in order to check and edit them if necessary.

Recovering files from the archive

Please make sure that the client version you are using is up-to-date. Technically, versions newer than 7.18 and 8.1.2 will work.

This information can be found in the basic notes on the archive.
